Yesterday’s international edition of USA Today (I picked it up at Heathrow) carried a full-page ad from the Ad Council, which donates its services to worthy causes every now and then.  This one, entirely in grey and white, displays logos from the Ad Council, USDA, and the Department of Health and Human Services (DHHS), the parent agency of FDA.

In inch-high letters, all caps: DO YOU WANT THAT SAFE OR MEDIUM-SAFE?

In quarter-inch letters, also caps: USE A FOOD THERMOMETER TO MAKE SURE YOU COOK RAW MEAT AND POULTRY TO A BACTERIA-KILLING TEMPERATURE.

The ad also displays the Cook, Clean, Chill, Separate logo and the admonition to “Keep your family safer from food poisoning.  Check your steps at foodsafety.gov.”

Mind you, I’m highly in favor of following food safety procedures at home.

But most food safety problems are not due to the failure of home cooks to use thermometers.

They are caused by failures to observe food safety procedures during commercial production and preparation.

Shouldn’t meat and poultry be safe when you buy it in the supermarket?

This ad implies that the principal responsibility for food safety lies with the end user—you.

If you get sick it’s your fault because you didn’t use a meat thermometer?

USDA and DHHS:  how about getting the Ad Council to encourage meat and poultry producers to make sure their products are safe in the first place.

In response to my post on tuna scrape, Professor Alan Reilly, Chief Executive, Food Safety Authority of Ireland (the equivalent of our FDA) sent this photograph of an actual tuna scrape label.

After I forwarded it to Bill Marler, he noticed that it is one of several photographs posted on the FDA’s tuna scrape recall web page).

The type is too small to read so I’ve done some cropping:

Professor Reilly asks:

What is puzzling me is why this product “minced tuna” was used in sushi products. The label (copy attached) clearly states that the product must be cooked before consumption and it is for industrial uses only (labelled not for retail).

Those are good questions, but here’s another, equally alarming.  What’s that strangely formatted Nutrition Facts label? It does not precisely follow FDA design or content requirements.

This is a red flag.  If the company is not following labeling rules, it might not be  following other rules either—safety, for example.

Safety?  Uh oh.

Bill Marler reports that the FDA “483 Inspection Report” on the Indian tuna processing facility is now available.  Read these quotes and shudder:

• Tanks used for storage of process waters have apparent visible debris, filth and microbiological contamination.
• There is no laboratory analysis for water used in ice manufacturing at the [redacted] facility to show the water used to make ice is potable.
• Apparent bird feces were observed on the ice manufacturing equipment at Moon Fishery; insects and filth were observed in and on the equipment.
• Tuna processed at your facility, which is consumed raw or cooked, comes in direct contact with water and ice.

I draw several lessons from this episode:

• Food is safer when cooked.
• Labels need to be read—and followed—carefully.
• Raw sushi is a high risk product, especially if it doesn’t cost much.
• The FDA needs to be doing a lot more inspecting of overseas facilities, and before they cause problems.

All of this means that we need a better food safety system, one that can address the enormous proportion of our food supply that comes to us from countries with weaker food safety standards.

Addition, May 17: Ben Embarek, a food safety scientist at the World Health Organization notes that the 483 report reveals that Moon’s HACCP plan did not list appropriate critical control points.  Anyone auditing the plan should have picked up the problems on paper, which is easier and less expensive to do than an on-site inspection.  But the FDA does not pre-audit international HACCP plans.  They are supposed to be cleared by exporting companies registered by FDA.  Comment: it’s hard to imagine that the current system can work, and it clearly does not.

The Government Accountability Office is complaining again about the inadequacies of the American food safety system, and with good reason.

Its 2012 Annual Report, Opportunities to Reduce Duplication, Overlap and Fragmentation, Achieve Savings, and Enhance Revenue, says that the food safety system is:

fragmented and results in inconsistent oversight, ineffective coordination, and inefficient use of resources.

In 2007, GAO added food safety to its list of high-risk areas that warrant attention by Congress and the executive branch.

More recently GAO found that this fragmentation extends to the responsibilities across multiple agencies to defend food and agricultural systems against terrorist attacks and natural disasters…Many of these activities are everyday functions or part of the broader food and agriculture defense initiative and would be difficult for the agencies to separately quantify.

This report repeats what the GAO has been saying since the early 1990s:

there is no centralized coordination to oversee the federal government’s overall progress in implementing the nation’s food and agriculture defense policy.

Because the responsibilities outlined in this policy (HSPD-9) are fragmented and cut across at least nine different agencies, centralized oversight is important to ensure that efforts are coordinated to overcome this fragmentation, efficiently use scarce funds, and promote the overall effectiveness of the federal government.

Reminder: the present food safety system is mainly divided between two agencies: USDA (meat and poultry) and FDA (everything else).

Centralized oversight of food safety?  What a concept.

The FDA has just released a classy new report on Global Engagement, summarizing its efforts to deal with issues raised by the globalization of drugs, medical devices, and foods.

This is a big deal.  In 2009, 300,000 foreign facilities in more than 150 countries exported $2 trillion worth of FDA-regulated products to the United States.

Given these numbers alone, the FDA has some challenges.

In 2011, one out of every six FDA-regulated food products in the U.S. came from abroad.  Imports of fresh fruits, vegeta­bles, coffee, tea, and cocoa have more than doubled since 2000.

We import:

• 80 percent of seafood
• ~50 percent of fresh fruit
• ~20 percent of fresh vegetables

As the report explains,

• Many products entering the United States are made or grown in countries that lack the necessary regulatory over­sight to ensure their quality and safety.
• Greater numbers of suppliers, more complex products, and intricate multinational supply chains introduce risks to product safety and quality, including more oppor­tunities for economic adulteration and the spread of contaminated products.
• FDA can only realistically inspect a small percent­age (less than 3 percent) of the enormous volume of food products arriving at U.S. ports of entry, making it crucial that the Agency focus on ensuring that food products meet U.S. standards before they reach the United States.

To deal with this problem, the FDA has opened offices in:

• China: Beijing, Shanghai, and Guangzhou
• India: New Delhi and Mumbai
• Latin America: San Jose, Costa Rica; Santiago, Chile; and Mexico City, Mexico
• Europe: Brussels, Belgium; London, United Kingdom; and Parma, Italy
• Asia-Pacific: FDA headquarters
• Sub-Saharan Africa: Pretoria, South Africa
• Middle East and North Africa: Amman, Jordan

The FDA seems seriously concerned about its global initiatives and the safety problems posed by our globalized food supply.

The volume seems impossible to manage.  Let’s hope the FDA’s efforts do some good.

My Q and A column in the San Francisco Chronicle appears on the first Sunday of every month.  This one is about safety problems with tuna scrape.

Q: I had no idea that the tuna in my sushi roll was scraped off the bones in India, ground up, frozen, and shipped to California. Is this another “slime” product? Can I eat it raw?

A: No sooner did the furor over lean, finely textured beef (a.k.a. “pink slime”) die down than we have another one over sushi tuna. On April 13, the Food and Drug Administration said Moon Marine USA, an importing company based in Cupertino, was voluntarily recalling 30 tons of frozen raw ground yellowfin tuna, packaged as Nakaochi scrape.

Centers for Disease Control and Prevention investigations linked consumption of Nakaochi scrape sushi to about 250 diagnosed cases and an estimated 6,000 or so undiagnosed cases of illness caused by two rare strains of salmonella. Among the victims who were interviewed, more than 80 percent said they ate spicy tuna sushi rolls purchased in grocery stores or restaurants.

Scrape refers to the meat left on fish skeletons after the filets are cut off. This is perfectly good fish, but difficult to get at. I once visited an Alaskan salmon packing plant and asked what happened to the delicious looking meat between the bones. The answer: pet food. (Lucky cats.)

A hot commodity

But tuna is too valuable to leave behind, and companies in India use special devices to scoop out the meat, combine it with scrapings from many other fish, chop the mixture, freeze it in blocks, and ship it to importers in the United States. Unlike “pink slime,” tuna scrape is not treated with ammonia or anything else to kill harmful bacteria.

Nevertheless, it is supposed to be safe. The FDA requires producers of imported foods to follow established safety plans. Although the United States imports about 80 percent of seafood sold domestically, the FDA only inspects 1 or 2 percent.

This means we have to rely on the diligence of international food producers in following safe-handling procedures, and of U.S. importers in verifying safety through pathogen testing. But even well-intentioned producers can make safety errors, especially when dealing with high-risk foods.

Tuna scrape is very high risk. Its supply chain is long, complicated and international, leaving many opportunities for contamination. And it is eaten raw.

This tuna scrape came from a single processing plant in India owned by Moon Marine International of Taiwan. Tuna are plentiful off the Indian coast, and the tuna processing industry is expanding rapidly. India has dozens, perhaps hundreds, of fish processing facilities, but most are relatively small and their number, size and geographical dispersion make monitoring difficult.

Safe handling issues

The frozen scrape blocks are supposed to be held at subzero temperatures throughout shipping. Even so, they pose a safety risk. They combine the scrapings from many fish. One contaminated scraping can contaminate the entire lot.

And subzero freezing may kill some salmonella, but large fractions can survive, remain viable, and multiply when the blocks are thawed.

Once the tuna scrape arrived in America, I’m guessing it was trucked to Cupertino and from there to retailers and distributors who further trucked them to restaurants and grocery stores. There, sushi chefs thawed the scrape and used it to make spicy tuna rolls.

Tuna scrape is used in supermarket-grade sushi, not the fancy stuff. Sushi used to be – and still is, in places – an art form requiring exceptional skills. In Japan, sushi chefs can train for as many as 10 years to learn how to recognize the freshest, safest and most delicious fish. Sushi served by such chefs is made to order. It is never pre-prepared. It can be breathtakingly expensive.

But in America, sushi has gone mainstream. You can find prepackaged sushi rolls at practically any supermarket or convenience store, at a cost equivalent to hamburger.

Cheap sushi is made with cheap ingredients – hence, Nakaochi scrape – by chefs with far less training. A typical certification program for sushi chefs in this country can be completed in two or three months. Some offer certification online. Although these programs address safe food-handling procedures, the training is necessarily superficial.

What are the odds?

Sushi aficionados argue that while raw fish is never perfectly safe, the safety odds are much better when the chef is well trained, and the fish are freshly caught and cut to order in front of you. By their standards, tuna scrape is suitable only for pet food, which is at least cooked to kill pathogens.

If anything, the tuna scrape outbreak teaches why it is so important to know where food comes from and how it is made. Caveat emptor.

Addition, May 14:  Bill Marler reports that the FDA “483 Inspection Report” on the Indian tuna processing facility is now available.  Here are excerpts from the most revealing section:

Tanks used for storage of process waters have apparent visible debris, filth and microbiological contamination…There is no laboratory analysis for water used in ice manufacturing at the [redacted] facility to show the water used to make ice is potable…Apparent bird feces were observed on the ice manufacturing equipment at Moon Fishery; insects and filth were observed in and on the equipment…Tuna processed at your facility, which is consumed raw or cooked, comes in direct contact with water and ice.

Politics does indeed make strange bedfellows. 

The American Enterprise Institute, a conservative (to say the least) think tank, has just issued a report on reforming the farm bill to ensure a safer food system.  Its stunning conclusion:

More feasibly, in the short to medium term, changes in food safety regulation should aim at correcting inconsistencies or loopholes that exist in US food safety laws.

For example, policymakers could merge the FSIS and the FDA to allow for a better allocation of resources and exploit potential return to scales.

Standardizing states’ detection systems for food-borne illnesses and collecting better data about the incidence of food-borne illnesses would make firms more accountable and help construct better food safety policies.

Merge the food safety functions of USDA and FDA?  This, of course, is precisely what food safety advocates and the Government Accountability Office have been urging since the early 1990s. 

Now, maybe, it has a chance?

Apparently as a result of a need to cut costs, the USDA is changing the way its inspectors oversee chicken processing.

As Dana Milbank of the Washington Post puts it, this is

a proposal to allow chicken slaughterhouses to inspect themselves — eliminating those pesky federal monitors who have the annoying habit of taking diseased birds out of the food supply.

Even if the Obama administration were inclined to bring down capitalism with an orgy of overregulation, there isn’t enough money in the budget to enforce the rules on the books.  That’s what the chicken fight is about: Spending cuts…are a form of de facto deregulation (my emphasis).

The New York Times account of this policy change notes that inspectors:

had observed numerous instances of poultry plant employees allowing birds contaminated with fecal matter or other substances to pass. And even when the employees try to remove diseased birds, they face reprimands….

The Agriculture Department proposal allows poultry plants to speed up their assembly lines to about 200 birds per minute from 140, hampering any effort to examine birds for defects.

But that’s not all.  The Center for Livable Future at Johns Hopkins  reports that meal made from chicken by-products (in this case, feathers) contains arsenic and antibiotics such as fluoroquinolones that have been banned by the FDA for use in poultry.

A study published in Environmental Science & Technology found fluoroquinolone antibiotics in 8 of 12 samples of feather meal collected from six states and China.

A second study found arsenic in every sample of feather meal tested.

These findings indicate that poultry producers are using these drugs, even though they are not allowed to.

The U.S. poultry industry raises about 9 billion chickens and 80 million turkeys for human consumption each year.  Meal made from their feathers is commonly added to feed for chickens, pigs, cattle, and fish.  This could be a reentry route into the human food supply for such drugs.

Nicholas Kristof explains in the New York Times that these studies also found feather meal to contain

an antihistamine that is the active ingredient of Benadryl…[and] acetaminophen, the active ingredient in Tylenol.  And feather-meal samples from China contained an antidepressant that is the active ingredient in Prozac.

Poultry-growing literature has recommended Benadryl to reduce anxiety among chickens, apparently because stressed chickens have tougher meat and grow more slowly. Tylenol and Prozac presumably serve the same purpose.

Such findings indicate some of the worst problems with industrial poultry production.  They result from pressures to produce chickens cheaply.  The faster chickens can be pushed to grow, the less feed they consume and the cheaper they are to raise.

I don’t know what the best system for inspection might be, but I’m quite sure that leaving food safety oversight to the discretion of the packers is not a good idea.  Neither is speeding up the line.  And neither is feeding chickens drugs that can affect human health.

Here is even more evidence for the need for an overhaul of our food safety system.

A single food safety system anyone?

Dr. Michael Osterholm, the director of the University of Minnesota’s Center for Infectious Disease Research and Policy, and a well known advocate for safe food, has asked for a correction to my post of several days ago.

He thinks the post can be interpreted as suggesting that he has financial ties to Beef Products, Inc (BPI), the maker of the ingredient.

In reading over the post, I can see how that interpretation is possible.  That was certainly not my intention.

Dr. Osterholm tells me that neither he nor his University of Minnesota Center have financial, consultative, or political ties to BPI or to Cargill (which also makes the ingredient).

His concerns about the issue have to do with facts about food safety and with correcting misinformation.

I did not mean to suggest otherwise, have personally apologized to him, and have edited the post accordingly.
