Drug-Testing Company Tied to N.C.A.A. Draws Criticism

KANSAS CITY, Mo. — A wall in one of the conference rooms at the National Center for Drug Free Sport displays magazine covers, each capturing a moment in the inglorious history of doping scandals in sports.

Don Catlin, formerly of U.C.L.A.’s Olympic Analytical Lab, has raised questions about drug testing at colleges.

The images show Ben Johnson, the sprinter who lost his 1988 Olympic gold medal after testing positive; and Barry Bonds, the tarnished home run king; and Lyle Alzado, one of the first pro football players to admit to steroid use.

“People always assume that it’s the athletes at the top of their sport or the top of their game that are using,” said Frank Uryasz, Drug Free Sport’s founder and president. “But I can assure you that’s not the case. There’s always that desire to be the best, to win. That permeates all level of sport — abuse where you just wouldn’t expect it.”

Over the past quarter-century, athletes like Johnson, Bonds and Alzado stirred widespread concern about doping in sports.

Professional leagues without drug-testing programs have put them in; leagues with drug-testing programs have strengthened them. Congress and medical experts have called on sports officials at all levels to treat doping like a scourge.

It was in this budding American culture of doping awareness that Uryasz found a niche business model. He has spent the past decade selling his company’s services to the country’s sports officials.

The company advises leagues and teams on what their testing protocols should look like — everything from what drugs to test for to how often athletes will be tested to what happens to the specimens after testing. It also handles the collection and testing of urine samples, often with the help of subcontractors.

Drug Free Sport provides drug-testing programs for high school, college and professional leagues.

A privately held company with fewer than 30 full-time employees, it counts among its clients Major League Baseball, the N.F.L., the N.B.A., the N.C.A.A. and about 300 individual college programs.

Many, if not all, of the players on the field Monday night for the Bowl Championship Series title game between Alabama and Notre Dame have participated in a drug-testing program engineered by Drug Free Sport.

Uryasz says his company’s programs provide substantial deterrents for athletes who might consider doping.

Critics, however, question how rigorous the company’s programs are. They say Drug Free Sport often fails to adhere to tenets of serious drug testing, like random, unannounced tests; collection of samples by trained, independent officials; and testing for a comprehensive list of recreational and performance-enhancing drugs.

The critics, pointing to a low rate of positive tests, question Drug Free Sport’s effectiveness at catching athletes who cheat. Since the company began running the N.C.A.A.’s drug-testing program in 1999, for example, the rate of positive tests has been no higher than 1 percent in any year — despite an N.C.A.A. survey of student-athletes that indicated at least 1 in 5 used marijuana, a banned substance. (The N.C.A.A. tests for marijuana at championship competitions but not in its year-round program.)

Uryasz said the rate of positive tests was not meaningful. “I don’t spend a lot of time on the percent positive as being an indicator of very much,” he said.

Independent doping experts contend that having a contract with Drug Free Sport allows sports officials to say they take testing seriously without enacting a truly stringent program.

Don Catlin, the former head of U.C.L.A.’s Olympic Analytical Lab, best known for breaking the Bay Area Laboratory Co-operative doping ring, oversaw the testing of many of Drug Free Sport’s urine samples when he was at U.C.L.A. He said the work by Drug Free Sport and similar companies could be used to mislead fans.

“The problem with these schools is they all want to say they’re doing drug testing, but they’re not really doing anything I would call drug testing,” he said.

A Company’s Origins

Uryasz said he became interested in working with student-athletes while tutoring them as an undergraduate at Nebraska. After he graduated, he earned an M.B.A. from Nebraska and worked in health care administration in Omaha. He said he heard about an opening at the N.C.A.A. through a friend.

Driven in part by scandals in professional sports, the N.C.A.A. voted at its 1986 annual convention to start a drug-testing program.

Chinese Newspaper, Southern Weekend, Challenges Censors

Pool photo by

Xi Jinping at a meeting in Beijing in December. Unrest at an influential newspaper, Southern Weekend, has caught the public’s attention.

BEIJING — Turmoil at one of China’s leading newspapers is posing an early challenge to the measured political program of the new Chinese leader Xi Jinping, pitting a pent-up popular demand for change against the Communist Party’s desire to maintain a firm grip.

The unrest at the influential newspaper Southern Weekend began last week when censors appeared to have toned down the paper’s New Year’s letter to readers — traditionally a call for progress in the new year. That caused journalists and their supporters — including students at nearby Sun Yat-sen University — to issue open letters expressing their outrage.

“Our yielding and our silence has not brought a return of our freedom,” the students said in their petition on Sunday, according to a translation by Hong Kong University’s China Media Project. “Quite the opposite, it has brought the untempered intrusion and infiltration of rights by power.”

By Sunday night, the protests had transformed into a real-time melee in the blogosphere — a remarkable development in a country where protests of all kinds are tightly controlled and the media largely know the boundaries of permissible debate.

In this case, the newspaper’s economics and environmental news staffs appeared to declare that they were on strike, while editors loyal to the government shut down or took control of the paper’s official microblogs. One widely distributed staff declaration with 90 signatures said the publication’s microblogs were no longer authentic.

“I don’t know whether it will be a full strike, but I do know the joint statement about the confiscation of the Weibo account has widespread support,” said one former editor, referring to a microblogging site and speaking on the condition of anonymity.

The turmoil at the Guangzhou-based newspaper resonates especially strongly among politically aware Chinese because Mr. Xi chose southern China for a tour after taking power in November. He made a pilgrimage to nearby Shenzhen, where the father of China’s economic reforms, Deng Xiaoping, initiated them two decades ago.

Indeed, Mr. Xi seems to be casting himself in the mold of Deng, who was known for bold economic reforms but who also brooked no opposition to the rule of the Communist Party.

The latest indication was a speech Mr. Xi made that also was published in newspapers on Sunday. Speaking to senior leaders, Mr. Xi repeatedly invoked Deng, especially on the need to adhere to “socialism with Chinese characteristics,” a phrase often used to mean a combination of pragmatic policies and one-party rule. He also praised the prereform era, in what appeared to be an effort to appeal to harder-line Communists.

But part of the reason for the clamor for reforms are hopes that Mr. Xi himself has raised. So far he has won praise by calling for China’s constitutional protections to be put in effect, ordering officials to cut pomp and setting in motion an anticorruption campaign.

These actions seem to have prompted the calls for even bolder reforms.

Beyond the unrest at Southern Weekend, editors of the edgy historical journal Yanhuang Chunqiu published a cover article last week arguing that the existing Constitution offered a basis for political reform and that the party’s failure to abide by it was a central cause of political instability. On Friday, the magazine’s Web site was shut down, with officials claiming that it had failed to update its registration.

A message posted by the journal about the shutdown was forwarded 31,000 times, provoking many scathing criticisms of the government. The chief editor, Wu Si, said the journal’s staff had filed the paperwork and could be back online in 10 days.

Optimists say they hope the measures against the two publications were the result of recalcitrant officials appointed by the departing team of Hu Jintao and Wen Jiabao, whose decade in power was marked by an overriding desire for stability. Many members of Mr. Xi’s team will not take office until the annual meeting of the National People’s Congress in March, and it could take years for Mr. Xi to put allies into important positions of power.

“If Xi does not remove people and promote some officials, his new policies — if he has any — will be sunk by the old people,” said a senior editor at a top party newspaper who asked to remain anonymous because of the delicacy of the subject. “The conflicts between the old and the new have just emerged.”

Chinese politics since Deng’s time have been defined by similar tensions between liberalization and reaction. But Mr. Xi also confronts millions of increasingly outspoken Internet users whose outpourings can confound even China’s heavy censorship.

Zhan Jiang, a professor of media at the Beijing Foreign Studies University, said the public anger showed how expectations had risen. “Currently in China people are unusually sensitive to developments like this, and so the reaction has been quite intense,” Mr. Zhan said.

Some are less sure that the atmosphere is more open, saying the media shutdowns have occurred because Mr. Xi has avoided taking a clear position.

“There are still no clear rules on the media, and so officials stick to using their habitual ways to control the media,” said Li Datong, a prominent Chinese newspaper editor fired for his views. “There won’t be any change until Xi Jinping enunciates any ideas about major change.”

Other commentators doubt this will happen. They note that in previous jobs Mr. Xi upheld the status quo and that now that he has reached the pinnacle of his career he is unlikely to support systemic reform.

“This is a traditional viewpoint: if you change the emperor you’ll have a change of policy and maybe some new, hopeful things,” said the exiled Chinese political commentator Zhang Ping, who goes by the pen name Chang Ping. “But I don’t think this is likely, because you still have an emperor.”

New High for Tuna at Tokyo Fish Sale

TOKYO — Tokyo’s main fish market ushered in the new year with an auction on Saturday that resulted in the highest price paid here, and probably anywhere, for a tuna.

A Tokyo-based sushi restaurant chain owner paid 155.4 million yen, or about $1.76 million, for a 488-pound bluefin, or about $3,600 per pound.

The record price was offered at the year’s first auction at the Tsukiji fish market, which provides Tokyo with much of its fresh fish. Restaurant owners from Japan and elsewhere in Asia compete annually for the prestige of buying the year’s first tuna, whose meat is prized by sushi fans. Conservationists warn that bluefin has been severely overfished.

The winning bidder was Kiyoshi Kimura, president of the company that runs the Sushi Zanmai chain. The bluefin was caught by a fisherman from Oma, a town renowned in Japan as the source of the most delicious tuna.

Slipstream: Legislation Would Regulate Tracking of Cellphone Users

THERE are three things that matter in consumer data collection: location, location, location.

E-ZPasses clock the routes we drive. Metro passes register the subway stations we enter. A.T.M.’s record where and when we get cash. Not to mention the credit and debit card transactions that map our trajectories in comprehensive detail — the stores, restaurants and gas stations we frequent; the hotels and health clubs we patronize.

Each of these represents a kind of knowing trade, a conscious consumer submission to surveillance for the sake of convenience.

But now legislators, regulators, advocacy groups and marketers are squaring off over newer technology: smartphones and mobile apps that can continuously record and share people’s precise movements. At issue is whether consumers are unwittingly acquiescing to pervasive tracking just for the sake of having mobile amenities like calendar, game or weather apps.

For Senator Al Franken, the Minnesota Democrat, the potential hazard is that by compiling location patterns over time, companies could create an intimate portrait of a person’s familial and professional associations, political and religious beliefs, even health status. To give consumers some say in the surveillance, Mr. Franken has been working on a locational privacy protection bill that would require entities like app developers to obtain explicit one-time consent from users before recording the locations of their mobile devices. It would prohibit stalking apps — programs that allow one person to track another person’s whereabouts surreptitiously.

The bill, approved last month by the Senate Judiciary Committee, would also require mobile services to disclose the names of the advertising networks or other third parties with which they share consumers’ locations.

“Someone who has this information doesn’t just know where you live,” Mr. Franken said during the Judiciary Committee meeting. “They know the roads you take to work, where you drop your kids off at school, the church you attend and the doctors that you visit.”

Yet many marketers say they need to know consumers’ precise locations so they can show relevant mobile ads or coupons at the very moment a person is in or near a store. Informing such users about each and every ad network or analytics company that tracks their locations could hinder that hyperlocal marketing, they say, because it could require a new consent notice to appear every time someone opened an app.

“Consumers would revolt if this was the case, and applications could be rendered useless,” said Senator Charles Grassley, the Iowa Republican, who promulgated industry arguments during the committee meeting. “Worse yet, free applications that rely on advertising could be pushed by the consent requirement to become fee-based.”

Mr. Franken’s bill may seem intended simply to protect consumer privacy. But the underlying issue is the future of consumer data property rights — the question of who actually owns the information generated by a person who uses a digital device and whether using that property without explicit authorization constitutes trespassing.

In common law, a property intrusion is known as “trespass to chattels.” The Supreme Court invoked the legal concept last January in United States v. Jones, in which it ruled that the government had violated the Fourth Amendment — which protects people against unreasonable search and seizure — by placing a GPS tracking device on a suspect’s car for 28 days without getting a warrant.

Some advocacy groups view location tracking by mobile apps and ad networks as a parallel, warrantless commercial intrusion. To these groups, Mr. Franken’s bill suggests that consumers may eventually gain some rights over their own digital footprints.

“People don’t think about how they broadcast their locations all the time when they carry their phones. The law is just starting to catch up and think about how to treat this,” says Marcia Hofmann, a senior staff lawyer at the Electronic Frontier Foundation, a digital rights group based in San Francisco. “In an ideal world, users would be able to share the information they want and not share the information they don’t want and have more control over how it is used.”

Even some marketers agree.

One is Scout Advertising, a location-based mobile ad service that promises to help advertisers pinpoint the whereabouts of potential customers within 100 meters. The service, previously known as ThinkNear and recently acquired by Telenav, a personalized navigation service, works by determining a person’s location; figuring out whether that place is a home or a store, a health club or a sports stadium; analyzing weather and other local conditions; and then showing a mobile ad tailored to the situation.

Eli Portnoy, general manager of Scout Advertising, calls the technique “situational targeting.” He says Crunch, the fitness center chain, used the service to show mobile ads to people within three miles of a Crunch gym on rainy mornings. The ad said: “Seven-day pass. Run on a treadmill, not in the rain.”

When a person clicks on one of these ads, Mr. Portnoy says, a browser-based map pops up with turn-by-turn directions to the nearest location. Through GPS tracking, Scout Advertising can tell when someone starts driving and whether that person arrives at the site.

Despite the tracking, Mr. Portnoy describes his company’s mobile ads as protective of privacy because the service works only with sites or apps that obtain consent to use people’s locations. Scout Advertising, he adds, does not compile data on individuals’ whereabouts over time.

Still, he says, if Congress were to enact Mr. Franken’s location privacy bill as written, it “would be a little challenging” for the industry to carry out, because of the number and variety of companies involved in mobile marketing.

“We are in favor of more privacy,” Mr. Portnoy says, “but it has to be done within the nuances of how mobile advertising works so it can scale.”

A SPOKESMAN for Mr. Franken said the senator planned to reintroduce the bill in the new Congress. It is one of several continuing government efforts to develop some baseline consumer data rights.

“New technology may provide increased convenience or security at the expense of privacy and many people may find the trade-off worthwhile,” Justice Samuel Alito wrote last year in his opinion in the Jones case. “On the other hand,” he added, “concern about new intrusions on privacy may spur the enactment of legislation to protect against these intrusions.”

The New Old Age: Murray Span, 1922-2012

One consequence of our elders’ extended lifespans is that we half expect them to keep chugging along forever. My father, a busy yoga practitioner and blackjack player, celebrated his 90th birthday in September in reasonably good health.

So when I had the sad task of letting people know that Murray Span died on Dec. 8, after just a few days’ illness, the primary response was disbelief. “No! I just talked to him Tuesday! He was fine!”

And he was. We’d gone out for lunch on Saturday, our usual routine, and he demolished a whole stack of blueberry pancakes.

But on Wednesday, he called to say he had bad abdominal pain and had hardly slept. The nurses at his facility were on the case; his geriatrician prescribed a clear liquid diet.

Like many in his generation, my dad tended towards stoicism. When he said, the following morning, “the pain is terrible,” that meant agony. I drove over.

His doctor shared our preference for conservative treatment. For patients at advanced ages, hospitals and emergency rooms can become perilous places. My dad had come through a July heart attack in good shape, but he had also signed a do-not-resuscitate order. He saw evidence all around him that eventually the body fails and life can become a torturous series of health crises and hospitalizations from which one never truly rebounds.

So over the next two days we tried to relieve his pain at home. He had abdominal x-rays that showed some kind of obstruction. He tried laxatives and enemas and Tylenol, to no effect. He couldn’t sleep.

On Friday, we agreed to go to the emergency room for a CT scan. Maybe, I thought, there’s a simple fix, even for a 90-year-old with diabetes and heart disease. But I carried his advance directives in my bag, because you never know.

When it is someone else’s narrative, it’s easier to see where things go off the rails, where a loving family authorizes procedures whose risks outweigh their benefits.

But when it’s your father groaning on the gurney, the conveyor belt of contemporary medicine can sweep you along, one incremental decision at a time.

All I wanted was for him to stop hurting, so it seemed reasonable to permit an IV for hydration and pain relief and a thin oxygen tube tucked beneath his nose.

Then, after Dad drank the first of two big containers of contrast liquid needed for his scan, his breathing grew phlegmy and labored. His geriatrician arrived and urged the insertion of a nasogastric tube to suck out all the liquid Dad had just downed.

His blood oxygen levels dropped, so there were soon two doctors and two nurses suctioning his throat until he gagged and fastening an oxygen mask over his nose and mouth.

At one point, I looked at my poor father, still in pain despite all the apparatus, and thought, “This is what suffering looks like.” I despaired, convinced I had failed in my most basic responsibility.

“I’m just so tired,” Dad told me, more than once. “There are too many things going wrong.”

Let me abridge this long story. The scan showed evidence of a perforation of some sort, among other abnormalities. A chest X-ray indicated pneumonia in both lungs. I spoke with Dad’s doctor, with the E.R. doc, with a friend who is a prominent geriatrician.

These are always profound decisions, and I’m sure that, given the number of unknowns, other people might have made other choices. Fortunately, I didn’t have to decide; I could ask my still-lucid father.

I leaned close to his good ear, the one with the hearing aid, and told him about the pneumonia, about the second CT scan the radiologist wanted, about antibiotics. “Or, we can stop all this and go home and call hospice,” I said.

He had seen my daughter earlier that day (and asked her about the hockey strike), and my sister and her son were en route. The important hands had been clasped, or soon would be.

He knew what hospice meant; its nurses and aides helped us care for my mother as she died. “Call hospice,” he said. We tiffed a bit about whether to have hospice care in his apartment or mine. I told his doctors we wanted comfort care only.

As in a film run backwards, the tubes came out, the oxygen mask came off. Then we settled in for a night in a hospital room while I called hospices — and a handyman to move the furniture out of my dining room, so I could install his hospital bed there.

In between, I assured my father that I was there, that we were taking care of him, that he didn’t have to worry. For the first few hours after the morphine began, finally seeming to ease his pain, he could respond, “OK.” Then, he couldn’t.

The next morning, as I awaited the hospital case manager to arrange the hospice transfer, my father stopped breathing.

We held his funeral at the South Jersey synagogue where he’d had his belated bar mitzvah at age 88, and buried him next to my mother in a small Jewish cemetery in the countryside. I’d written a fair amount about him here, so I thought readers might want to know.

We weren’t ready, if anyone ever really is, but in our sorrow, my sister and I recite this mantra: 90 good years, four bad days. That’s a ratio any of us might choose.

China Says Reporter for The Times Was Not Expelled

BEIJING — Responding for the first time publicly to the case of a reporter for The New York Times who was forced to leave mainland China, the country’s Foreign Ministry said on Friday that he had not been expelled but that his visa application had simply been filed incorrectly.

Speaking at the Foreign Ministry’s daily news briefing, Hua Chunying, a spokeswoman, said foreign news organizations were to blame for the departure on Monday of Chris Buckley, a 45-year-old Australian who had been a correspondent for Reuters until September, when he rejoined The Times.

Ms. Hua said the ministry had not been properly informed of his changed status.

“So far, we have neither received any notice of resignation (from Reuters), nor has the press card, which was issued by the information department (of the Foreign Ministry), been returned by Chris Buckley,” Ms. Hua said, according to the Xinhua news agency. “So, we do not know who his real boss is now.”

When Mr. Buckley’s visa, which had been issued while he worked for Reuters, ran out on Dec. 31, he and his family were forced to fly to Hong Kong, despite repeated requests from The Times for a new visa to be issued.

Ms. Hua said Mr. Buckley had not been expelled.

“There has been no such thing as a rejection of a visa extension, and there is no such thing as Chris being expelled,” Ms. Hua said, according to The Associated Press.

On a related matter, The Times is also waiting for the visa of its new Beijing bureau chief, Philip P. Pan, to be issued. Mr. Pan first requested a visa last March. The English- and Chinese-language Web sites of The Times have been blocked in China since October, when it published an investigative article about the finances of the family of China’s premier, Wen Jiabao.

This article has been revised to reflect the following correction:

Correction: January 4, 2013

An earlier version of this article misstated the job title of Philip P. Pan. He is the new Beijing bureau chief of The New York Times, not the China bureau chief.

Media Decoder Blog: Hulu's Chief Is Leaving, Raising Questions About Its Future

8:39 p.m. | Updated
Jason Kilar, the Web wizard who turned Hulu from a punch line into a popular source of online video, said on Friday that he would step down as the site’s founding chief executive in the next three months.

The announcement is certain to turn up the volume on something that’s a constant hum in the media industry: speculation about the future of Hulu — and if it has one at all. Its owners, the Walt Disney Company, Comcast and the News Corporation, also run the ABC, Fox and NBC networks, and they do not agree about what to do with the Web site. Perversely, the more popular Hulu becomes, the more of a problem it is for the owners, since it may be taking viewers and advertising dollars away from their core television businesses.

Mr. Kilar never saw it that way, however. He was Hulu’s best advocate, sometimes clashing with the network executives on Hulu’s board and arguing that they had to keep investing in the site, since television’s future will surely involve Internet distribution.

For many Americans, that future is already here: Hulu’s streams of TV shows attract 30 million unique visitors a month via computers and untold millions more via tablets and Internet-connected television sets. Three million pay for Hulu Plus, its subscription arm — not bad for a start-up once ridiculed as “ClownCo.”

Mr. Kilar declined an interview request on Friday. In an e-mail message to employees, he gave no indication why he was moving on or what he might do next. “My decision to depart has been one of the toughest I’ve ever made,” he said.

He said his departure would take effect within the first quarter of the year. No successor was named.

Mr. Kilar, a former executive at Amazon, has in the past been mentioned for a number of prominent jobs in Silicon Valley. He was a top candidate last year for the chief executive position at Yahoo, but Hulu said he declined to be considered. The job later went to Marissa Mayer, a longtime Google employee.

His departure comes just several months after the only independent owner of Hulu, Providence Equity Partners, sold its 10 percent stake, originally bought for $100 million, for $200 million. Mr. Kilar and other employees also sold their stakes in the company at that time, netting Mr. Kilar about $40 million, according to an executive with knowledge of the transaction.

On Friday, there was widespread praise for Mr. Kilar for steering Hulu through sometimes turbulent seas. “He defied enormous odds, built from scratch one of the top five digital video brands, created two viable and growing businesses (free and pay) and got his well-deserved payday — not bad for five years’ work,” J. B. Perrette, who used to help oversee NBC’s investment in Hulu and now runs Discovery Communication’s digital operations, said in an e-mail.

That said, Mr. Kilar’s announcement did not entirely surprise many in the industry. During his tenure, he sometimes clashed with the owners on Hulu, exemplifying the divide between new, disruptive modes of distribution like the Internet and the more traditional operations at major media companies. As the parent companies pulled back on the amount of ABC, Fox and NBC programming provided to Hulu, the Web site invested in original content to fill the gaps and attract attention. That investment effort continues, led by one of Mr. Kilar’s deputies, Andy Forssell, but many in the industry say they believe that Hulu’s future remains fuzzy.

An internal memo obtained by Variety in August showed that the owners may want to change their agreements with Hulu so that it is no longer the exclusive distributor of repeats of television shows like “The Office” and “Family Guy.” That way, the owners could also sell repeat rights to online video services like YouTube, Netflix or Amazon.

Some of the owners also wanted more advertisements on the site, which had revenue of about $700 million last year but is not yet believed to be profitable. Much of the revenue came from Hulu Plus, and therein lies another fault line: the owners may concentrate on the paid part to the detriment of the free streaming part.

The owners had no comment about any of that on Friday, though. Robert Iger, Disney’s chief executive, called Mr. Kilar an integral part of the Hulu story and said in a statement, “We are proud of his achievements, we appreciate what he’s built, and we share his confidence in his team’s ability to drive Hulu forward from here.”

Rich Tom, the site’s chief technology officer, will also depart in the first quarter.

This month, Richard Greenfield, an analyst at BTIG Research, predicted that News Corporation would seek to acquire its competitors’ stakes in Hulu in 2013. Comcast, he said, has no managerial control of Hulu and Disney “appears increasingly less interested” in the site.

In August, News Corporation said that Jonathan Miller, the company’s chief digital officer since 2009 and a vocal champion of Hulu, would leave the company. Mr. Miller represented News Corporation on the Hulu board and had helped the media company broker a stake in Roku. News Corporation has had some high-stakes stumbles in technology with both Myspace and its tablet-only publication, The Daily, which has led some analysts to expect the company to tread cautiously with future digital investments like Hulu. And Chase Carey, the No. 2 to the chief executive of News Corporation, Rupert Murdoch, is said to be less enamored with the service.

Mr. Murdoch, however, praised Mr. Kilar for “building Hulu into one of the leading online video services available today.” He added, “It’s incredibly well positioned for the road ahead.”

F.D.A. Offers Rules to Stop Food Contamination

The Food and Drug Administration on Friday proposed two sweeping rules aimed at preventing the contamination of produce and processed foods, which has sickened tens of thousands of Americans annually in recent years.

A new rule imposed by the F.D.A. would establish different standards for ensuring the purity of water that touches fruits and vegetables.

The proposed rules represent a sea change in the way the agency polices food, a process that currently involves taking action after contamination has been identified. It is a long-awaited step toward codifying the food safety law that Congress passed two years ago.

Changes include requirements for better record keeping, contingency plans for handling outbreaks and measures that would prevent the spread of contaminants in the first place. While food producers would have latitude in determining how to execute the rules, farmers would have to ensure that water used in irrigation met certain standards and food processors would need to find ways to keep fresh food that may contain bacteria from coming into contact with food that has been cooked.

New safety measures might include requiring that farm workers wash their hands, installing portable toilets in fields and ensuring that foods are cooked at temperatures high enough to kill bacteria.

Whether consumers will ultimately bear some of the expense of the new rules was unclear, but the agency estimated that the proposals would cost food producers tens of thousands of dollars a year.

A big question to be resolved is whether Congress will approve the money necessary to support the oversight. President Obama requested $220 million in his 2013 budget, but Dr. Margaret Hamburg, commissioner of the F.D.A., said “resources remain an ongoing concern.”

Nonetheless, agency officials were optimistic that the new rules would protect consumers better.

“These new rules really set the basic framework for a modern, science-based approach to food safety and shift us from a strategy of reacting to problems to a strategy for preventing problems,” Michael R. Taylor, deputy commissioner for foods and veterinary medicine, said in an interview. The Food and Drug Administration is responsible for the safety of about 80 percent of the food that Americans consume. The rest falls to the Agriculture Department, which is responsible for meat, poultry and some eggs.

One in six Americans becomes ill from eating contaminated food each year, the government estimates; most of them recover without concern, but roughly 130,000 are hospitalized and 3,000 die. The agency estimated the new rules could prevent about 1.75 million illnesses each year.

Congress passed the Food Safety Modernization Act in 2010 after a wave of incidents involving tainted eggs, peanut butter and spinach sickened thousands of people and led major food makers to join consumer advocates in demanding stronger government oversight.

But it took the Obama administration two years to move the rules through the regulatory agency, prompting complaints that the White House was more concerned about protecting itself from Republican criticism than about public safety.

Mr. Taylor said that the delay was a function of the wide variety of foods and the complexity of the food system. “Anything that is important and complicated will always take longer than you would like,” he said.

The first rule would require manufacturers of processed foods sold in the United States to come up with ways to reduce the risk of contamination. Food companies would be required to have a plan for correcting problems and for keeping records that government inspectors could audit.

An example might be to require the roasting of raw peanuts at a temperature guaranteed to kill salmonella, which has been a problem in nut butters in recent years. Roasted nuts would then have to be kept separate from raw nuts to further reduce the risk of contamination, said Sandra B. Eskin, director of the safe food campaign at the Pew Charitable Trusts.

“This is very good news for consumers,” Ms. Eskin said. “We applaud the administration’s action, which demonstrates its strong commitment to making our food safer.”

The second rule would apply to the harvesting and production of fruits and vegetables in an effort to combat bacterial contamination like E. coli, which is transmitted through feces. It would address what advocates refer to as the “four Ws” — water, waste, workers and wildlife.
