FSIS has just issued the Verification Testing for Non-O157 STEC for Beef Trimmings. While this new wrinkle in the E. coli-Beef trim issue has caused a lot of concern, the anticipated outcome may not come anywhere close to the hype.
Domestic product http://www.fsis.usda.gov/OPPDE/rdad/FSISNotices/29-12.pdf
Imported http://www.fsis.usda.gov/OPPDE/rdad/FSISNotices/30-12.pdf
Background - On June 4th, FSIS will begin testing for six non-0157 serogroups (O26, O45, O103, O111, O121, and O145) in addition to O157:H7. Like E. coli O157:H7, these E. coli serogroups are viewed as adulterants in non-intact raw beef products and product components (raw ground beef and beef trim).
A few interesting notes:
1) FSIS does not expect establishments to reassess their HACCP plans because of this testing implementation. (Facilities should address non-O157 STEC in their Hazard Analysis.)
2) FSIS will not schedule a for-cause FSA in response to a non-O157 positive sample result. Outside of that, FSIS will follow Directive 10,010.3 Rev 3 including resampling. (And corrective action for positive product, which will include holding and dispositioning of positive product). http://www.fsis.usda.gov/OPPDE/rdad/FSISDirectives/10010.1Rev3.pdf
3) “FSIS recognizes that establishments will begin taking steps to address non-O157 STECs in their HACCP systems and performing activities to gather data to validate that their food safety systems are adequately designed to control non-O157 STECs. Establishments are to document and identify in their initial validation activity plans the time frame in which they will have accumulated sufficient data to conclude that their food safety systems are demonstrated to be adequate to control for the relevant non-O157 STECs”.
4) FSIS will not require establishments to adjust their existing testing programs for non-O157 STEC.
5) A confirmed positive is an isolate that has stx and eae genes and one or more of the target serogroup genes (O45, O26, O113, etc.). A positive is not just a positive for the genes, but the bacterium must be isolated and biochemically confirmed, so establishments should be prepared to deal with false positives.

FDA's Reportable Food Registry Report Provides Important Insight into Food Supply Issues
The FDA just released the second annual report for the Reportable Food Registry, RFR.
http://www.fda.gov/Food/FoodSafety/FoodSafetyPrograms/RFR/ucm200958.htm?source=govdelivery
The Reportable Food Registry is an electronic portal where food companies report issues with a food where that food is likely to cause illness. So if Company A ships nuts to Company B, and Company B tests those nuts and finds Salmonella, then by law, Company B must report this incident to the FDA via the Reportable Food Registry.
This has been a great tool in keeping unsafe food out of commerce. It allows FDA to use industry information to police the food supply chain.
Industry professions can see an important aspect of this RFR report is that it indicates where in the food system issues have occurred. Accordingly, companies who purchase products can look at this list and find issues with products or ingredients they use and then ensure these items are addressed through HACCP or a supplier control program. Here are some examples (Table 6) – undeclared allergens in bakery products, Salmonella in nuts, spices/seasonings, and produce, Listeria in prepared foods and dairy. Reports on Imported foods (Table 13) shows a slight increase from year 1 to 2 in total recalls, but certainly an increase in the number of Salmonella related issues coming in on imported foods.
It is also important to note that the RFR can put companies at risk of being pulled into a recall. This was the case last year when Salmonella was discovered in hydrolyzed vegetable protein. And even with companies whose process rendered the ingredient as no risk (these companies were going to put the HVP into a product that was to be cooked), they still recalled product. Traceability is paramount in being able to quickly respond to a supplier issue that gets reported to FDA by another company.

Case of BSE, or Mad Cow, found in California
A cow in California was diagnosed with BSE, or Mad Cow. This is the fourth documented case of BSE in a cow in the US.
It poses no real risk to the US food supply.
The cow, more than 30 months old of age, had died and was to be rendered. Because the cow died, it was tested for BSE. Analysis resulted in what is being called an atypical case, and thus is believed to have occurred spontaneously through a mutation.
BSE is a neurological disease causing brain and spinal cord degeneration. It is caused by a prion which is misfolded protein, that aggregates in the brain to form plagues. These prions can arise in animals that have a specific gene variant, and then this disease can be transmitted to other animals that come in contact with infected tissue of the diseased animal. This transmission occurs because the infectious prion causes a protein in the normal animal’s brain to deform into the infectious state.
BSE in cows has been a problem in the past when animal byproducts were used to supplement animal feed. In the UK more than 180,000 cows may have been infected (starting in 1986) and resulted in as many as 165 people dying within 10 years afterward (up to 2009). In humans, the CJD variant can occur when people consume infected tissue.
The practice of feeding animal by-products to ruminants is banned in the United States. Additionally, the US has an active monitoring system for all suspect animals and older animals as well as controls for the removal of SRMs (specific risk materials), including spinal and brain tissue, during slaughter.
New case of mad cow disease in California

WASHINGTON - The first new case of mad cow disease in the U.S. since 2006 has been discovered in a dairy cow in California, but health authorities said Tuesday the animal never was a threat to the nation's food supply.
The infected cow, the fourth ever discovered in the U.S., was found as part of an Agriculture Department surveillance program that tests about 40,000 cows a year for the fatal brain disease.
No meat from the cow was bound for the food supply, said John Clifford, the department's chief veterinary officer.
"There is really no cause for alarm here with regard to this animal," Clifford told reporters at a hastily convened news conference.
Mad cow disease, or bovine spongiform encephalopathy (BSE), is fatal to cows and can cause a fatal human brain disease in people who eat tainted beef. The World Health Organization has said that tests show that humans cannot be infected by drinking milk from BSE-infected animals.

Update - Salmonella linked to tuna used in sushi
Update 5/3/12
CDC reports that there is now close to 260 people infected with two different strains of Salmonella.
CDC Release 5/2/12
http://www.cdc.gov/salmonella/bareilly-04-12/index.html
Based on an epidemiologic link and results of
laboratory testing, CDC has combined this Salmonella Bareilly investigation with an ongoing
multistate outbreak investigation of Salmonella serotype Nchanga infections. The two
associated PFGE patterns have been grouped together as the "outbreak strains."
A total of 258 persons infected with the outbreak
strains of Salmonella Bareilly (247 persons)
or Salmonella Nchanga (11 persons) have been
reported from 24 states and the District of Columbia.
4/17/12
According to the CDC, the Salmonella Bareilly that caused close to 150 illnesses has been linked to tuna used in sushi. The raw tuna served was frozen, but of course, was not cooked. While freezing will eliminate parasites, it will not eliminate Salmonella. The majority of tuna linked to this outbreak was from India. The US importer, Moon Marine, has begun recalling close to 59,000 lbs of tuna.
When producing a ready-to-eat food such as sushi grade tuna, the highest degree of sanitation and operating cleanliness must be maintained. This requires that the producer maintain tight production controls and procedures each and every day. This tuna meat, or tuna scrape, is a lower grade product and is essentially meat that was scrapped from the backbone of the tuna and had the look of a ground product.
A lawsuit has already been filed against the importer. As an importer, they have the responsibility for ensuring the processing plants they purchase from have adequate quality and safety systems in place.
Multistate Outbreak of Salmonella Bareilly Infections Associated with a Raw Scraped Ground Tuna Product
http://www.cdc.gov/salmonella/bareilly-04-12/index.html
CDC Release 4/17/2012
A total of 141 persons infected with the outbreak strain of Salmonella Bareilly have been reported from 20 states and the District of Columbia.
The number of ill persons identified in each state is as follows: Alabama (2), Arkansas (1), Connecticut (6), District of Columbia (2), Florida (1), Georgia (6), Illinois (13), Louisiana (3), Maryland (14), Massachusetts (9), Mississippi (2), Missouri (4), New Jersey (8), New York (28), North Carolina (2), Pennsylvania (6), Rhode Island (5), South Carolina (3), Texas (4), Virginia (8), and Wisconsin (14). 21 ill persons have been hospitalized, and no deaths have been reported.
Collaborative investigation efforts of state, local, and federal public health agencies indicate that a frozen raw yellowfin tuna product, known as Nakaochi Scrape, from Moon Marine USA Corporation is the likely source of this outbreak of Salmonella Bareilly infections. Nakaochi Scrape is tuna backmeat that is scraped from the bones of tuna and may be used in sushi, sashimi, ceviche, and similar dishes. The product looks like raw ground tuna.
Consumers should not eat the recalled product, and retailers should not serve the recalled raw Nakaochi Scrape tuna product from Moon Marine USA Corporation.
This investigation is ongoing. CDC and state and local public health partners are continuing surveillance to identify new cases.

NY Times reports E. coli on Chicken...oh noooooo
What would we do without the occasional ‘shocking’ story about raw meat containing bacteria, in this case, a study that E. coli was found on chicken? Yes, raw meat, including chicken, can and will have E. coli associated with it, as well as some pathogens such as Salmonella and Campylobacter. This will occur whether it is conventionally processed, organic, or even farm raised. Those processing chicken put in steps to help reduce the level of bacteria, but it is nearly impossible to eliminate all bacteria on a raw product (one that you would still want to buy). I don’t want a farmer or processor treating my chicken to a point that eliminates all of the bacteria, and neither should you. It would not be a chicken that you would want to buy.
Have we become such germaphobes that we cannot longer tolerate the thought that E. coli might be on a raw chicken or raw beef. What, you don’t think that soon after you put on your underwear that you have a few E.coli on them? Or on our hands after we use the restroom? And what do we do, we wash them. And for raw meat and poultry products…..we cook them (and keep our kitchen counter clean as well).
A few problems with this study, one pointed out by our own Dr. Cutter in the NY Times article below. (You can link to the published report http://www.pcrm.org/health/reports/fecal-contamination-in-retail-chicken-products.)
They constantly refer to the E. coli contamination as feces. Although linked, these are two different images. Yes, there may be a few E.coli in your underwear, or even on your hands after you use the restroom, but would you call it feces? Have you ever seen feces on a raw chicken breast? Does your chicken breast smell like poop? E. coli is of fecal origin, and it can cross contaminate onto food and surfaces such as your hands, but to what degree are feces particles present…microscopic at best. And if that thought still concerns you, then you better live in a bubble with your colon direct linked to the sewer pipe.
Another issue is that the study does not look at actual levels of E. coli per bird, just the absence or presence. Therefore, it is possible that there may only be an extremely low level of E.coli there…and based upon real scientific studies, we know that this is the case. So we start with a bird where there are billioins and billions of E. coli present in the intestine, the bird is eviscerated, cleaned, and packaged. Now, there only has be a few organisms present for the test to show a positive. I am surprised the number isn’t even higher….but that would be no more concerning.
Is it surprising that the person who conducted the study is a vegan? So what is the agenda? I have no problems with those people who choose not to eat meat. But please don’t push that agenda onto others through the use of ill designed studies.
The real take away…cook your food….and use a thermometer to verify.
48% of Chicken in Small Sample Has E. Coli
By STEPHANIE STROM
NY Times Published: April 11, 2012
A recent test of packaged raw chicken products bought at grocery stores across the country found that roughly half of them were contaminated with the bacteria E. coli.
E. coli, which the study said was an indicator of fecal contamination, was found in 48 percent of 120 chicken products bought in 10 major cities by the Physicians Committee for Responsible Medicine, a nonprofit group that advocates a vegetarian diet among other things. The study results were released Wednesday.
“Most consumers do not realize that feces are in the chicken products they purchase,” said Dr. Neal D. Barnard, president of the group. “Food labels discuss contamination as if it is simply the presence of bacteria, but people need to know that it means much more than that.”
Food safety specialists said the findings were a tempest in a chicken coop, particularly because the test was so small and the E. coli found was not a kind that threatened public health.

Seven more people have been confirmed as victims of a nationwide salmonella outbreak, including one more person in Chicago, state and federal health officials announced today.
In all, 100 people across the country and nine in Illinois have been made ill in the outbreak, whose source has still not been determined, officials with the Centers for Disease Control said.
The outbreak, which was first confirmed Wednesday, involves salmonella bareilly, an unusual strain of the salmonella bacterium, CDC officials said.
It has been connected to reported illnesses that have occurred between Jan. 28 and March 25 in 19 states, plus the District of Columbia. Those affected said they had eaten sushi, sashimi or similar foods in the week before their symptoms began, according to the CDC.

FDA releases 2nd edition of Bad Bug Book
FDA has recently released the second edition of the Bad Bug Book.
http://www.fda.gov/downloads/Food/FoodSafety/FoodborneIllness/FodborneIllnessFoodbornePathogensNaturalToxins/BadBugBook/UCM297627.pdf
This is a great online reference for foodborne pathogens and toxins (bacteria, viruses, parasites, and natural toxins). There are 5 new chapters in this book – below is a quick summaries of each (as well as grayanotoxin). Each chapter also has an insert – For Consumers: A Snapshot – that provides an overview of each pathogen.
Cronobacter - Causes illness, including bacteremia and meningitis, primarily in infants and immocompromised adults. Can survive in low moisture foods, and has been an issue in powdered infant formulas. “The illness it causes is rare, but when it occurs, infants younger than 2 months old are at highest risk. The death rate is high, from 10 percent to 80 percent… It can then multiply after liquid is added to the formula, especially if the formula is stored at an incorrect temperature, and cause illness in babies who drink it..” To avoid illness in infants, it is important to follow food safety instructions when preparing infant formula.
Enterococcus, “Anyone can become infected with the Enterococcus bacterium, but the people most likely to suffer serious problems are those who already have other serious illnesses. In otherwise healthy people, it may cause diarrhea, cramps, nausea, vomiting, fever, and chills, starting 2 to 36 hours after they eat contaminated food. Enterococcus can be passed to people in different ways, and not much is yet known about how often it’s transmitted by food. But it is known that meat and milk that aren’t processed or cooked properly or that are handled in unsanitary ways are among the foods that can transmit it. A major concern about Enterococcus is that it has become resistant to some antibiotics that were used to treat it – that is, those antibiotics no longer kill it. You can help protect yourself from getting foodborne illness from this and other bacteria or viruses by following basic food-safety tips; for example, by not using unpasteurized (“raw”) milk or certain cheeses and other food made from it, by thoroughly cooking meat or food that contains meat, and by washing your hands, kitchen equipment, and other surfaces before and after you handle food.”
Francisella tularensis, “The bacterium Francisella tularensis causes a disease called tularemia (nicknamed “rabbit fever”). Tularemia can take different forms, depending on how the bacterium enters the body. If it enters through the mouth when a person eats or drinks contaminated food or water, it can cause tularemia that affects the throat or intestines, although this is an uncommon form of the disease. Symptoms of this type range from mild to severe in otherwise healthy people, and it rarely causes death. In the more serious cases, untreated throat infection may spread to vital organs (such as the lungs, brain, or liver), and may cause extensive bowel damage, with bleeding and infection of the bloodstream, especially in people with weak immune systems. People can develop tularemia of the throat or intestines by eating undercooked meat from an infected animal (particularly rabbits) or drinking contaminated water. Eating food or drinking water contaminated by animal waste, such as rodent droppings, also can cause this form of tularemia and many other diseases. Cooking food well is one of the safety tips that can help protect you from getting this form of tularemia, especially if you eat the kind of wild animals known to be carriers, such as rabbits.”
Phytohaemagglutinin, “Eating undercooked bean can cause you to have extreme nausea, severe vomiting, and diarrhea. They contain a protein that’s found naturally in many plants (and animals, including humans), where it performs important functions. But when it reaches high levels in some plants, particularly kidney beans, the protein can act as a toxin. Cooking the beans properly destroys the toxin. Don’t use slow cookers (the kinds of pots that you plug in and that cook food at low temperatures for several hours) to cook these beans or dishes that contain them. Slow cookers don’t get hot enough to destroy the toxin in kidney beans. Studies done by British scientists suggest that beans should be soaked in water for at least 5 hours, the water poured away, and the beans boiled in fresh water for at least 30 minutes.”
Venomous fish, “lionfish (Pterois volitans), a known venomous species from the Pacific Ocean, recently has become invasive and over-abundant along the U.S. south Atlantic coast and in the waters surrounding several Caribbean island countries, presenting new opportunities for human consumption.”
Grayanotoxins – “If bees make their honey from the pollen and nectar of flowers from some types of rhododendron, the honey may contain grayanotoxin, a substance poisonous to humans. Other plants from the same family that may contain it, in the Eastern part of the U.S., include mountain laurel and sheep laurel. Sickness that results from eating honey that contains grayanotoxin is sometimes called “mad honey” poisoning. It has occurred in the past in the U.S., but now appears to be very rare here. Nausea and vomiting are common symptoms of grayanotoxin poisoning. A rarer symptom is burning, tingling, and numbness around the mouth. The toxin affects nerve cells, including not only the nerves that affect the brain, but also those that affect the heart and other muscles. For this reason, grayanotoxin poisoning causes not only problems like dizziness, weakness, confusion, vision disturbances, and heavy sweating and saliva flow, but also irregular or very slow heartbeat, low blood pressure, and fainting. These poisonings are rarely fatal.”

This is a great online reference for foodborne pathogens and toxins (bacteria, viruses, parasites, and natural toxins). There are 5 new chapters in this book – below is a quick summaries of each (as well as grayanotoxin). Each chapter also has an insert – For Consumers: A Snapshot – that provides an overview of each pathogen.
Cronobacter - Causes illness, including bacteremia and meningitis, primarily in infants and immocompromised adults. Can survive in low moisture foods, and has been an issue in powdered infant formulas. “The illness it causes is rare, but when it occurs, infants younger than 2 months old are at highest risk. The death rate is high, from 10 percent to 80 percent… It can then multiply after liquid is added to the formula, especially if the formula is stored at an incorrect temperature, and cause illness in babies who drink it..” To avoid illness in infants, it is important to follow food safety instructions when preparing infant formula.
Enterococcus, “Anyone can become infected with the Enterococcus bacterium, but the people most likely to suffer serious problems are those who already have other serious illnesses. In otherwise healthy people, it may cause diarrhea, cramps, nausea, vomiting, fever, and chills, starting 2 to 36 hours after they eat contaminated food. Enterococcus can be passed to people in different ways, and not much is yet known about how often it’s transmitted by food. But it is known that meat and milk that aren’t processed or cooked properly or that are handled in unsanitary ways are among the foods that can transmit it. A major concern about Enterococcus is that it has become resistant to some antibiotics that were used to treat it – that is, those antibiotics no longer kill it. You can help protect yourself from getting foodborne illness from this and other bacteria or viruses by following basic food-safety tips; for example, by not using unpasteurized (“raw”) milk or certain cheeses and other food made from it, by thoroughly cooking meat or food that contains meat, and by washing your hands, kitchen equipment, and other surfaces before and after you handle food.”
Francisella tularensis, “The bacterium Francisella tularensis causes a disease called tularemia (nicknamed “rabbit fever”). Tularemia can take different forms, depending on how the bacterium enters the body. If it enters through the mouth when a person eats or drinks contaminated food or water, it can cause tularemia that affects the throat or intestines, although this is an uncommon form of the disease. Symptoms of this type range from mild to severe in otherwise healthy people, and it rarely causes death. In the more serious cases, untreated throat infection may spread to vital organs (such as the lungs, brain, or liver), and may cause extensive bowel damage, with bleeding and infection of the bloodstream, especially in people with weak immune systems.

60 Minutes segment "Is Sugar Toxic?"
In case you missed it, here is the 60 Minutes segment on sugar, ‘Is Sugar Toxic?’.
http://www.youtube.com/watch?v=B56Gpf1f5_A
Too much sugar is bad, that is hard to deny. But with consumers having made it such a big component of their diet, will they be willing to change their diet? Hopefully segments like this will get people to think about their diet with the goal of reducing sugar….significantly.

FDA will not ban BPA at this time
The controversy will continue as FDA has decided not to ban BPA from food packaging materials at this time (due to inconclusive evidence). A ban would have had a huge impact on the food supply, as companies rushed to find suitable replacements. Continued study will occur.
U.S. Denies Request to Ban Chemical in Food PackagingBloomberg
By Jack Kaskey - Mar 30, 2012 6:07 PM ETFri Mar 30 22:07:58 GMT 2012
http://www.bloomberg.com/news/2012-03-30/u-s-denies-request-to-ban-chemical-in-food-and-drink-packaging.html
The U.S. Food and Drug Administration rejected a request to ban a contested chemical from cans and other packaging because opponents didn’t provide enough data to support a rule change.
Continued study of bisphenol A, known as BPA, including completion of federal studies currently in progress, is the most appropriate course of action, the agency said in an e-mail today. The chemical has been used in epoxy linings since the 1960s to extend the shelf life of canned foods and beverages.
Manufacturers of baby bottles and cups have stopped using polycarbonate containing BPA in response to consumer concerns it may affect children. Campbell Soup Co. (CPB) is among food makers phasing out the use of BPA, while beverage companies such asCoca-Cola Co. (KO) have kept the chemical, saying it’s safe.
“The information provided in your petition was not sufficient to persuade FDA, at this time, to initiate rulemaking to prohibit the use of BPA in human food and food packaging,”David H. Horsey, an acting associate FDA commissioner, said today in a letter to the Natural Resources Defense Council.
NRDC, a New York-based environmental advocacy group, petitioned the FDA in 2008 to ban its use in food and drinks packaging. BPA, produced by combining phenol and acetone, mimics the female hormone estrogen and may affect the brain and prostate gland in fetuses and young children, according to theNational Institutes of Health.
Quickly Processed
A ban would hurt profits at can-maker Silgan Holdings Inc. (SLGN)and others in the $60 billion industry, Ghansham Panjabi, an analyst at Robert W. Baird & Co., said before the FDA announcement. The biggest U.S. producer of BPA is Saudi Basic Industries Corp. (SABIC), followed by Bayer AG (BAYN) and Dow Chemical Co. (DOW)
About 4.7 million metric tons of BPA valued at about $8 billion will be produced this year, according to a report by GlobalData, a London-based publisher of business intelligence. Three times as much BPA goes into polycarbonate plastics, used in items ranging from plastic bottles to DVDs, as is used in epoxy resins.
The FDA plans to complete an updated safety review of BPA this year and will make any changes to the chemical’s status based on the science, Douglas Karas, an agency spokesman, said in an e-mail. People of all ages metabolize and rid their bodies of BPA faster than rodents used in studies, he said.
Federally funded research confirms that the human body quickly processes and eliminates BPA, making it “very unlikely” that the chemical causes harm, the American Chemistry Council, a Washington-based industry group, said in a statement today.
‘Dangerously Off Course’
Sarah Janssen, a senior scientist at the NRDC, said the FDA’s denial of a ban shows “a major overhaul” of chemical regulation is needed. The Environmental Working Group, a Washington-based advocacy group, said consumers can no longer trust the FDA to protect the health of their families.
“The agency has veered dangerously off course,” Jane Houlihan, the group’s senior vice president for research, said today in a statement. “Pregnant women and new parents should no longer think FDA has their backs.”
The North American Metal Packaging Alliance, a Washington-based industry group, praised the FDA’s decision.
“A ban without conclusive scientific evidence of risk would compromise the safety of canned foods and beverages,” John Rost, the alliance’s chairman, said in an e-mailed statement.

2 cases of botulism linked to tofu
Tofu, sold in NY City, has been linked to 2 cases of botulism. The tofu was purchased by a couple in a NY City store. The tofu was displayed in a non-refrigerated, water filled bin. This is the first cases of botulism in NYC in more than 15 years.
‘Tofu is made by coagulating soy milk and pressing the resulting curds. The process begins by soaking, grinding, boiling and straining dried or fresh soybeans. Coagulation of the protein and oil (emulsion) suspended in the boiled soy milk is the most important step in the production of tofu. This process is accomplished with the aid of coagulants. Two types of coagulants (salts and acids) are used commercially. The third type of coagulant, enzymes, is not yet used commercially but shows potential for producing both firm and "silken" tofu’. (adapted from Wikeapedia).
Clostridium botulinum spores would survive the boiling and then be able to grow in the non-refrigerated product (in the absence of a secondary inhibitor. Tofu products vary greatly, even in terms of inclusion of antimicrobial parameters.) The spores will germinate and grow in the protein rich, non-refrigerated product. The product sitting in water would ensure a sufficient water activity as well as help support an anaerobic environment, both essential for C. botulinum. As C. botulinum grows, it produces a neurotoxin. If ingested, the neurotoxin enters the bloodstream and shuts down muscle function, potentially leading to death through the inability of the victim to breath.
Tofu is a considered a potentially hazardous food (TCS food) and thus requires refrigeration during distribution, at retail, and by the consumer.
