Why wait for government redux: US food companies protecting against several forms of E. coli

The New York Times reports this morning that two major American companies, Costco Wholesale and Beef Products Inc., have gotten tired of waiting for regulators to act on non-O157 STECs (shiga-toxin producing E. coli) and are proceeding with their own plans to protect customers.

Last month, Costco, one of the nation’s largest food retailers, quietly began requiring its suppliers of bagged produce, including salad greens and mixes, apple slices and baby carrots, to test for a broad range of toxic E. coli.

“We know this is where we have to go and there’s no reason to wait,” said Craig Wilson, the food safety director of Costco. In the last two weeks, he said, most produce suppliers have added a test that can detect the strain from the European outbreak as well (E. coli O104).

The company also plans to test all of the ground beef sold at its warehouse stores. Costco operates a large ground beef plant in Tracy, Calif., and Mr. Wilson said the plant recently began evaluating testing procedures to detect the broader range of E. coli in the hamburger it makes and the beef trimmings that go into it.

As an added step, the company plans to ask suppliers of the trimmings to do their own testing, starting later this summer, he said.

Costco’s new testing requirements come as the federal government continues to drag its feet on what to do about the expanding E. coli threat. After four years of study, the United States Department of Agriculture finished drafting rules in January for how the industry should handle the “Big Six” E. coli in ground beef.

But the proposal has been stalled within the Office of Management and Budget, which reviews most federal regulations before they are released. Details of the proposal are confidential, but many in the industry expect that the rules would require testing or even make it illegal to sell ground beef that contained the additional strains of toxic E. coli.

The landscape is changing partly because tests created by U.S.D.A. scientists that can quickly pinpoint the presence in food of the “Big Six” E. coli are now being developed for commercial sale by test-kit companies. Some kits are already on the market.

12 sick: multistate outbreak of Salmonella Panama infections linked to cantaloupe

Cantaloupes are once again making people sick with salmonella.

An updated table of U.S. salmonella-in-cantaloupe outbreaks and recalls is available at:
http://bites.ksu.edu/cantaloupe-related-outbreaks

“The U.S. Centers for Disease Control is collaborating with public health officials in a number of states, including Oregon, Washington, California, and Maryland and the U.S. Food and Drug Administration (FDA) to investigate a multistate outbreak of Salmonella Panama infections. Investigators are using DNA analysis of Salmonella bacteria obtained through diagnostic testing to identify cases of illness that may be part of this outbreak.

“As of March 22, 2011, 12 persons infected with the outbreak strain of Salmonella Panama have been reported from Oregon (5 cases), Washington (4 cases), California (2 cases), and Maryland (1 case). Reported dates of illness onset range from February 5, 2011 to February 23, 2011. Ill persons range in age from less than 1 year old to 68 years old, with a median age of 12 years old. Sixty-six percent are male. Among ill persons, two have been hospitalized and no deaths have been reported.

“Collaborative investigative efforts of state, local, and federal public health and regulatory agencies have linked this outbreak to eating cantaloupe. Eleven of 12 ill persons reported eating cantaloupe in the week before illness. Ten of these 11 ill persons purchased cantaloupes before becoming ill at seven different locations of a national warehouse clubs. Information gathered with patient permission from membership card records helped determine that ill persons purchased cantaloupes sourced from a single farm. Product traceback information indicates these cantaloupes were harvested from single farm in Guatemala. FDA is working closely with CDC, authorities in states where illnesses have occurred and the firms involved to investigate the source of the contamination.

“On March 22, 2011, Del Monte Fresh Produce N.A., Inc. voluntarily recalled 4,992 cartons of cantaloupes, because they have the potential to be contaminated with Salmonella Panama. The cantaloupes were distributed through warehouse clubs in Alaska, California, Colorado, Idaho, Montana, Oregon, and Washington.

The recalled products consist of cartons of cantaloupes, each containing 4 plastic mesh sleeves with 3 cantaloupes per sleeve that were available for sale between March 10 and March 21, 2011. The cantaloupes, grown in and shipped from Del Monte Fresh’s farm Asuncion Mita in Guatemala, have a light brown color skin on the exterior with orange flesh. The recalled cartons of cantaloupes are dark brown cardboard with the “Del Monte” logo in red lettering and “cantaloupes” in yellow lettering on a green background. The cantaloupes have the lot codes: 02-15-24-10, 02-15-25-10, 02-15-26-10 and 02-15-28-10. No illness has been linked to cantaloupes from other sources.”

In farm-to-fork food safety, the idea is to minimize levels of contaminants throughout the system – salmonella should not be entering food service or home kitchens through cantaloupe. But if it does, here are ways to further minimize the spread and growth of salmonella.

The most important thing to do is to minimize the chances of contaminating the interior of the fruit. This is done by preventing the rind from contaminating the inside of the cantaloupe, either by direct contact or by cross-contamination. There are different methods used for preparing a cantaloupe, but there is disagreement over which is the most effective technique.

Blessed are the cheesemakers: feds arrest cheese that sickened 38

An outbreak of E. coli O157:H7 first became public in Nov. 2010, and would eventually sicken at least 38 people in several U.S. states. Investigators believe the source was Dutch Style Gouda Cheese produced by Bravo Farms of Traver, California from raw milk and sold primarily at Costco and Whole Foods Market stores.

The artisan cheese maker temporarily shut down.

Bravo was forced to quarantined stockpiles of cheese, and — no real surprise – of the 24 unpasteurized cheese samples investigators took, 15 tested positive for listeria and one tested positive for E. coli O157:H7.

According to the L.A. Times today, state and federal investigators found at least 50 live flies flitting around a processing area at Bravo. They also reported that a rabbit hopped out of a storage room, and a dairy worker scratched his chin then handled milled cheese with his bare hands.

On Thursday, U.S. marshals and Food and Drug Administration agents arrived at the cheesemaker and seized the Gouda, along with piles of Edam and blocks of white cheddar. All told, investigators have locked up more than 80,000 pounds of cheese. Prosecutors say it is all headed for the garbage disposal.

Worried that the cheese would somehow reach the public, and acting to shift the case from state to federal jurisdiction, the Justice Department used a civil legal mechanism to arrest a product — food — and essentially impound it.

Prosecutors filed a civil complaint in federal court in Sacramento last week that lists the cheese — not the farmers who made it — as defendants.

John Sheehan, director of the FDA’s dairy division, said the inspections came from concerns "about raw-milk cheese made under artisanal conditions" and a flurry of nine artisan cheese recalls last year. As of October, the FDA had inspected 102 facilities, some big, some small. Of the 147 samples taken, 32 tested positive for listeria. The inspections continue.

Bravo, which is cooperating with federal officials, has been cleared to make cheese again. It’s using pasteurized milk.

Bravo chesse now pasteurizing milk after making 38 barf

There is a disconnect between people who produce food, and those they sicken.

Three months after she sampled gouda cheese at a Costco and got sick, a Colorado teenager and her family have decided:

• no more ground beef;
• no more sharing friends’ lunch food at school; and,
• no more tasting cheese, salmon or any other morsels that food stores offer to entice customers.

Madisyn Kirby, 15, who lives in Castle Rock, said the illness that doubled her over in October "was the scariest, worst time of my life. I never want it to happen again."

Madisyn’s family has filed a lawsuit in Douglas County Court claiming Bravo Farms-brand Dutch Style Gouda Cheese she sampled at a Costco store near Park Meadows mall was contaminated by E. coli.’’

Federal and state health authorities linked Bravo Farms cheese to an E. coli outbreak last fall that caused 38 illnesses in Colorado and other Western states.

Yesterday, Bravo Farms co-owner Jonathan Van Ryn said the company’s back in business and last fall’s E. coli outbreak apparently resulted from "an isolated instance of one day’s production."

Madisyn probably doesn’t feel like an isolated case.

Alicia Cronquist, director of foodborne illness investigations at the Colorado Department of Public Health and Environment said a state health team detected "way too many E. coli cases being reported in the Denver metro area. … One thing that stood out was that many had sampled cheese at a large warehouse store. Home visits and lab tests pin-pointed gouda and other cheese samples as the source.

Jon Van Ryn estimated shutdown and recall costs at around $1.5 million and that Bravo, which has specialized in making raw-milk cheeses, is now pasteurizing its milk.

Duh.
 

33 sick in multistate outbreak of E. coli O157:H7 infections associated with cheese

The U.S. Centers for Disease Control has issued an alert to consumers and health professionals about an outbreak of E.coli O157:H7 in five states: Arizona, California, Colorado, New Mexico and Nevada. Based on current information, there is a link with the consumption of one of several cheeses offered for sampling and sale at the “cheese road show” that was held at Costco Warehouses in these states. This cheese—Bravo Farms Dutch Style Gouda Cheese (Costco Item 40654) manufactured by Bravo Farms, Traver CA—was sold and offered as free samples for in-store tasting from October 5 to November 1.

Consumers who have any of this cheese should not eat it. Instead, they should return the cheese to the place of purchase or dispose of it in a closed plastic bag placed in a sealed trash can. This will prevent people or animals, including wild animals, from eating it.

Thirty-three persons infected with the outbreak strain of E. coli O157:H7 have been reported from five states since mid-October. The number of ill persons identified in each state with this strain is as follows: AZ (15), CA (3), CO (10), NM (3) and NV (2). There have been 15 reported hospitalizations, 1 case of hemolytic uremic syndrome (HUS), and no deaths.

This is a rare strain of E. coli O157:H7 that has never been seen before in the PulseNet database. PulseNet is the national subtyping network made up of state and local public health laboratories and federal food regulatory laboratories that performs molecular surveillance of foodborne infections.

E. coli outbreak linked to Costco cheese samplers; 25 sick

In 2004, I spent a week at a cottage with a couple of my children in Eastern Ontario near Sandbanks Provincial Park on Lake Ontario. Lovely spot.

One rainy day, we toured around and ended up at a cheese shop. They produced the cheese in the factory at the back, and had a charming market outlet that seemed to trap tourists like bees on sap.

Upon entering the store, a sign declared, “HACCP – A food safety program; Hazard Analysis Critical Control Pont.” Cool. I asked one of the staff what it meant. She said she didn’t know. ??But beside the HACCP proclamation was a sign that read, “Public bathroom is out of order; for your convenience there is a blue Johnny on the spot behind the building.”?

No handwashing facilities or sanitizer. I watched people go to the porta potty and then come into the cheese shop and do what people do at quaint cheese shops: stick their unwashed hands into shared samples of curds (that’s one of my daughters looking disgusted in the middle, right, not because of the practice, but because I have to take pictures and be a food safety geek everywhere we go). HACCP really doesn’t mean much unless there is a culture of food safety amongst the employees and everyone involved in making a product, like cheese or deli meat.??

These public sampling stations can be cross-contamination nightmares. But the best hygiene won’t prevent food safety foul-ups when the product itself is contaminated.

Multiple sources are reporting tonight that Arizona and four other states reported cases of E. coli O157 in cheese products sold in Costco stores in October.

Twenty-five cases of Escherichia coli were confirmed by officials, 11 in Arizona lone, according to a statement issued Thursday by the Arizona Department of Health Services.

The outbreak appears to have been associated with cheese available for purchase at Costco "Cheese Road Shows," and Costco was working with state officials to remove the tainted product from its stores.

Early data from health officials suggests that Dutch-style Gouda cheese is the culprit. Costco is cooperating with the investigation: they have removed all suspect products from shelves and are notifying customers who purchased cheese from the road show.

A U.S. Food and Drug Administration press release states:]

• Bravo Farms Dutch Style Gouda cheese, (Costco item 40654) offered for sale and in cheese sampling events at Costco Wholesale Corporation (Costco) locations is preliminarily linked with an outbreak of E.coli O157:H7 infections.

• Consumers who have any of this cheese should not eat it. They should return the cheese to the place of purchase or dispose of it in a closed plastic bag and place in a sealed trash can to prevent people or animals, including wild animals, from eating it.

• Most people infected with E. coli O157:H7 develop diarrhea and abdominal cramps, but some illnesses may last longer and can be more severe. While most people recover within a week, some may develop a severe infection. Rarely, as symptoms of diarrhea improve, a type of kidney failure called hemolytic uremic syndrome (HUS) can occur; this can happen at any age but is most common in children under 5 years old and in older adults. People with HUS should be hospitalized immediately, as their kidneys may stop working and they may be at risk for other serious health problems.

• As of Thursday, November 4, 2010, 25 persons infected with the outbreak strain of E. coli O157:H7have been reported from five states since mid-October. The number of ill persons identified in each state with this strain is as follows: AZ (11), CA (1), CO (8), NM (3) and NV (2). There have been 9 reported hospitalizations, 1 possible case of hemolytic uremic syndrome (HUS), and no deaths.

Costco may need to check its suppliers. Again.
 

Lousy food safety auditors put public and brands at risk

The voluntary quality control system widely used in the nation’s $1 trillion domestic food industry is rife with conflicts of interest, inexperienced auditors and cursory inspections that produce inflated ratings, according to food retail executives and other industry experts.

I’ve been saying that for a long time, but this is the Washington Post version, published this morning. I especially like the pictures of the Montgomery Burns Awards for Outstanding Achievement in the Field of Excellence, courtesy of AIB, the Manhattan, Kansas-based audiots that gave a stellar rating to PCA and Wright Eggs just prior to terrible food safety outbreaks and revelations of awful production conditions (see below).

The system has developed primarily because large chain stores and food producers, such as Kellogg’s, want assurances about the products they place on their shelves and the ingredients they use in making food. To get that, they often require that their suppliers undergo regular inspections by independent auditors. This all takes place outside any government involvement and without any signals – stamps of approval, for instance – to consumers. (That’s four-year-old Zoe Warren, right, of Bethesda, who was hospitalized in 2007 after contracting salmonella poisoning after eating a chicken pot pie. The photo is by Susan Biddle for the Washington Post.)

The third-party food safety audit scheme that processors and retailers insisted upon is, in many cases, no better than a financial Ponzi scheme. The vast number of facilities and suppliers means audits are required, but people have been replaced by paper.

In fact, most foodmakers, even those with problems, sail through their inspections, said Mansour Samadpour, who owns a food-testing firm that does not perform audits. "I have not seen a single company that has had an outbreak or recall that didn’t have a series of audits with really high scores.”

Third-party food audits, like restaurant inspection, are a snapshot in time. Given the international sourcing of ingredients, audits are a requirement, but so is internal food safety intelligence to make sense of audits that are useful and audits that are chicken poop.

Industry experts say some "third-party" inspections can be rigorous. Those that audit using internationally recognized private benchmarks "are much more thorough," said Robert Brackett, former senior vice president of the Grocery Manufacturers Association. "But they’re less likely to be used because they are much more expensive."

Audits, inspections, training and systems are no substitute for developing a strong food safety culture, farm-to-fork, and marketing food safety directly to consumers rather than the local/natural/organic hucksterism is a way to further reinforce the food safety culture.

Will Daniels, who oversees food safety for Earthbound Farm, the folks who brought E. coli O157:H7 in bagged spinach in 2006 that sickened 199 and killed four, said, Earthbound regularly received top ratings in third-party audits, including one exactly a month before the tainted spinach was processed, adding,

"No one should rely on third-party audits to insure food safety."

“… if the incentive is to pass with flying colors, it creates a disincentive to air your dirty laundry and get dinged and lose a customer over it.”

After the E. coli outbreak, Earthbound put in place an aggressive testing and safety program that includes outside audits but also requires Earthbound’s own inspectors to show up unannounced to check suppliers. The company tests its greens for pathogens when they arrive from farms and again when they are packaged.

Too bad Earthbound didn’t figure all this out after the 28 other outbreaks involving leafy greens prior to the deadly 2006 outbreak.

Cost is another factor.

Food companies often choose the cheapest auditors to minimize the added expense of inspections, which range from about $1,000 to more than $25,000.

The foodmakers can prepare for audits because they often know when inspectors will show up.

And auditors have a range of experience and qualifications, from recent college graduates to retired food industry veterans. They sometimes walk through a plant, ticking off a checklist to produce a score, Samadpour said. Basic inspections do not typically include microbial sampling for bacteria.

In a written response to questions, Brian Soddy, AIB‘s vice president of marketing and sales, said company audits are intended to give food manufacturers "guidance and education for improvement."

Producers have the ultimate responsibility, he said, adding that the audits are voluntary and not intended to replace any FDA regulatory inspections.
AIB said last week that it is reevaluating its "superior" and "excellent" rating systems because they "have led to confusion in the wake of recent incidents," Soddy wrote.

Some retailers include inspections as just one piece of their safety programs.

Costco, for example, has its own inspectors but also requires its estimated 4,000 food vendors to have their products inspected according to a detailed 10-page list of criteria. Private auditors must X-ray all products for "sticks and stones, bones in seafood – anything you can think of that might be in hot dogs, baked goods, outside of produce," said Craig Wilson, Costco’s assistant vice president for food safety and quality assurance.

Costco maintains an approved list of about nine audit firms. The list does not include AIB.

Wal-Mart requires suppliers of private-label food products sold in its stores and Sam’s Club to be audited using private internationally recognized standards.

In addition to conducting its own product testing, Giant Food requires its vendors to be audited from a list of about a dozen approved firms.

Costco and Wal-Mart – doing food safety right

Retired Jack-in-the-Box food safety guru David Theno, told hundreds of tree fruit growers at the 105th annual meeting of the Washington State Horticultural Association in Wenatchee on Monday, Dec. 7 that regarding food safety,

"It doesn’t necessarily cost more to do it right. Costco and Wal-Mart are huge drivers of food safety and are willing to spend a little more."

 

Costco, Tyson, reach new deal on testing for dangerous E. coli

The N.Y. Times is reporting in tomorrow’s editions that retail giant Costco has struck a new accord on testing for the pathogen E. coli.

Costco’s food safety director and seemingly decent dude, Craig Wilson, said the company would begin buying beef trimmings for making hamburger from Tyson, one of the largest beef producers, after an agreement reached with Tyson this week that allows Costco to test the trimmings before they are mixed with those from other suppliers.

The United States Department of Agriculture has encouraged such testing as a way to make hamburger safer, but some of the largest slaughterhouses have resisted the added scrutiny for fear that one grinder’s discovery of E. coli will lead to expanded recalls of beef sent to other grinders, The New York Times reported Sunday.

Costco is one of the few large grinders to test ingredients for the pathogen as they arrive at its plant, and Mr. Wilson said Tyson had declined to sell trimmings to the company, citing its testing.

A Tyson spokesman has declined to respond to the accusation, but said that the company did not prohibit grinders from testing and that some of its customers did conduct some of their own testing, beyond the testing that Tyson performs.
