CDC MMWR - Pet Rats Source of Seoul Virus (a Type of Hantavirus) - 2017

Considering a new pet rat?  Well, as part of the assessment, you may need to consider Seoul virus.  A report in MMWR reviews a 2017 outbreak of Seoul virus that had been linked to pet Norway rats.  In addition to two individuals who became ill and 183 who were serum positive,   "the investigation identified 31 facilities in 11 states with human and/or rat Seoul virus infections; six facilities also reported exchanging rats with Canadian ratteries."

Seoul virus is a type of hantavirus that causes symptoms ranging from mild influenza-like illness to severe disease with kidney failure and even death.  Norway rats are an asymptomatic carriers for the virus and transmit this virus to humans through contact with contaminated rat urine or droppings, or inhalation of virus particles in dust from contaminated bedding.  This is the first known case of pet rats being the source for human infection.

Norway rats, also known as brown rats, are considered a pest for food operations and can be the source of a number of different pathogens.  With a high birth rate and a diet that can consist of most anything, rat issues in a food facility can be an issue, being very difficult to eradicate once the rodents become established.  So the thought of owning a rat, is difficult for many..  And now, if this Seoul virus is not enough to make you think twice, just have to watch Willard.

What is the Likelihood That Salmonella is On Your Chicken...or Beef...or Pork

USDA FSIS released their yearly sampling results that indicate the prevalence, or percent positive samples, for raw meat products.  As FSIS points out, "These calculations may vary significantly from the actual prevalence of the population, but FSIS cannot make a more precise calculation with the data currently available."  It is important to note that this does not evaluate the amount present, only if any are present.

Beef - In ground meat, Salmonella was present in just over 2% of the samples while pathogenic E. coli was present in 0.05% of samples.  While the prevalence of E. coli is low, there is still a risk of it being present, and considering the seriousness of the illness (and the fact that Salmonella could be present as well) it still remains important to cook meat to the proper temperature.

Pork - While there is extremely low to no risk for pathogenic E. coli, there is a higher risk of Salmonella being present in pork compared to beef.  For cuts, the prevalence of Salmonella is over 7%, but in comminuted pork meat (ground, stuff used in sausages), the prevalence is 22 percent.  Cook those brats to the right temperature.

Chicken - as the chicken moves from whole to parts to ground, the prevalence increases for both Salmonella and Campylobacter.   For whole chickens, there is a prevalence of 5.8% for Salmonella and 1.9% for Campylobacter.  In mechanically separated meat, the prevalence is almost 76% for Salmonella and 23% for Campylobacter.

Turkey - the stated prevalence is lower than that for chicken with whole birds at 0.56% for Salmonella and 0.16% for Campylobacter.  Much of difference between whole turkey and chicken may be due in part to how they are sampled, with a sponge being used for turkeys and a whole bird rinse used for chickens.

In the end, the risk is there, so it remains important to properly cook raw meat and poultry products.  And of course, to use a thermometer to verify.

Panera Recalls Cream Cheese Products After Positive Listeria Sample

Panera Bread is conducting a recall of all 2 oz. and 8 oz. cream cheese products sold in its U.S. bakery-cafes. This recall was initiated after samples of one variety of 2 oz. cream cheese from a single production day showed a positive result for the presence of Listeria monocytogenes. The company is recalling all varieties of unexpired 2 oz. and 8 oz. cream cheese products with an expiration date on or before 4/2/18, even though it was found in only one production run.

Recalling all unexpired product is a preemptive move. Too often with Listeria related recalls, companies try to minimize the recall to the one date only to have to recall additional product when they find they did not have sufficient control on Listeria in the processing environment.

Neglected Parasitic Infections of Poverty - Impact on Mental Health

An article in the NY Times brings to light the issue of neglected parasitic infections that may impact mental health.  In this case, Toxocara, a roundworm that lives in the intestines of stray or poorly kept cats and dogs, that can have health impacts on humans who become infected - breathing, liver function, eyesight and even intelligence.  The impact of infection on the brain is not well understood, but "has been linked to lower intelligence and epilepsy".  This is an issue in poorer areas where there are more stray cats and dogs.

Another common parasitic infection, that from Taxoplasmosis gondii, has been linked to cases of schizophrenia.  As we know,  cats are a definitive host for this parasite.

In a 2014 piece sited in the NY Times article, the author discusses a group of parasites that have been linked to mental performance and illness.  The author states,  "These chronic infections may partially account for the achievement gap noted among socioeconomically disadvantaged students."  He further states, "additional information has determined that the neglected infections of poverty also cause important psychiatric and neurological effects on vulnerable populations in the southern United States."  A table from that article summarizes this impact.

Federal Court Upholds Hefty Prison Sentences for PCA Executives in 2008 Salmonella Outbreak

A federal appeals court upheld the sentences handed down in the Peanut Corporation of America case where Salmonella-contaminated peanut butter was allowed to be sold by company executives. 
 - PCA president Stewart Parnell’s 28-year prison term
 - Operation manager - Michael Parnell’s 20-year prison sentence 

 - Quality assurance director - Mary Wilkerson- 5-year prison sentence 

In this 2008/2009 outbreak, over 700 people become infected with Salmonella after eating the contaminated PCA peanut products.  "The outbreak led to one of the largest food recalls in U.S. history, and Peanut Corp. permanently shuttered its operations.  Stewart Parnell had directed PCA to retest products that had tested positive for salmonella until a negative result was obtained, the appeals court said. The company also shipped peanut products before receiving test results and even shipped products after receiving confirmed, positive results."

California - Health Officials Warn People to Be Aware of Poisonous Wild Mushrooms

California officials warn consumers about the risks of eating wild mushrooms that may be poisonous. In over 14 months, there have been 1,038 reported cases where poisonous mushrooms were ingested. Some of these cases resulted in severe health issues including liver failure.

Generally, wild mushrooms are not allowed to be offered for sales. This is because of the difficulty in determining how to approve a 'wild mushroom expert'.

 From the US Food Code - 3-201.16 Wild Mushrooms.

Frozen RTE Meatballs Recalled Due to Listeria Concerns

Rich Products Corporation, a Vineland, N.J. establishment, is recalling approximately 3,420 pounds of RTE beef meatball products produced on Dec 17, 2017 due to the potential for Listeria contamination.  "The problem was discovered on Jan. 24, 2018 when FSIS received notification from the firm that they shipped adulterated product into commerce."

A concern for FSIS is that because this is a frozen product, people may have put into freezers and not check to see if this is the recalled lot.  Another concern may be that if this one lot is positive for Listeria, what about other other production lots.

While it is not indicated how the company determined the product had a Listeria contamination issue, it is important to note that the product was produced over a month prior to issuing the recall.  So either internal testing was delayed or a customer company did the testing.  If the former, then one would expect a test-and-hold procedure for the frozen product.

The risk - although this product will likely be heated before being served, as a fully cooked product, the heating instructions will be for heat and serve rather than fully cooking the product.  The heat-and-serve heating conditions may not be sufficient to eliminate the organisms present.

This Week in Mislabeled Products - Week Ending 1/26/18

Eggs not on Label - Perdue Foods LLC, a Monterey, Tenn. establishment, is recalling approximately 530 pounds of chicken products due to misbranding and undeclared allergens -the product contains eggs which is not declared on the product label. The problem was discovered by the firm while performing routine label verification activities.

Supplier Mislabels Protein Source - Bulletproof 360, Inc. is voluntarily recalling one lot #1017088 of Bulletproof Collagen Protein dietary supplement due to undeclared milk.  This voluntary recall was initiated after we discovered that bulk whey (milk) protein was mis-labeled as collagen protein by our third-party manufacturer during the manufacturing process. 

Wrong Label Applied - Sun Noodle of Carlstadt, NJ is voluntarily recalling one lot of their retail Tonkotsu Ramen because it is mis-labeled. While it is labeled Tonkotsu, the actual flavor packet inside is Assari Shoyu, which contains an additional undeclared allergen of fish (sardines).  The decision to recall this product was initiated after it was discovered that the product had the wrong label applied to the product, and did not accurately represent what was packaged. Subsequent investigation indicated that the problem was caused by mis-labeling of the product at the New Jersey facility.

Allergens and Colors Missing from Label - A Puerto Rico company is collecting the following PACHECO brand products because they may contain undeclared allergens (Wheat, Soy, Egg, Milk) and artificial colors not listed in ingredients (Red # 40, Yellow # 5, Yellow # 6.)

Frozen Green Beans and Mixed Veggies Recalled After Pet Food Customer Test Indicates Listeria

National Frozen Foods Corporation (NFFC) is voluntarily recalling a limited quantity of Not-Ready-To Eat IQF green beans and IQF mixed vegetables because they have the potential to be contaminated with Listeria monocytogenes.  The recall was initiated based on a 3rd party test result of the IQF Green Beans only by a downstream customer that revealed that the finished products may potentially be contaminated with the bacteria.

This customer was a company who manufactured foods for pets using restaurant grade ingredients.  They also issued a recall for the pet foods.  "JustFoodForDogs (JFFD) of Los Alamitos, CA, is voluntarily recalling its Beef & Russet Potato, Fish & Sweet Potato and Turducken dog food meals in all sizes. JFFD uses 100% USDA and other restaurant grade ingredients in all of its pet food, and because the green beans used in these meals may be contaminated with Listeria monocytogenes".  "While testing demonstrates that only several dates of production were affected, out of an abundance of caution, JFFD is recalling all of the above mentioned products made from the dates of November 1, 2017 through January 14, 2018. These represent Best By lot code dates on all three of the JustFoodForDogs’ recalled products of 11/01/18 through 01/14/19."

This is another case of a not-ready-to-eat product being recalled for Listeria.  In this case, a the pet food customer who purchased this product to use  as an ingredient in making another product, tested and found Listeria.  Was this customer considering this a RTE product or did the see that there may be some issue where the product coudl be under-cooked?  Regardless, it then triggered the selling company to issue a recall, and thus affecting product sold to customers that would not have had any issue because they would have followed label instructions for cooking.

For the seller, this information needs to be part of the sales agreement with a realistic understanding of the capabilities of meeting that agreement- how the product is going to be used, what are the microbiological requirements that were stated on the specification,  will there be any testing of the ingredient was going - because as in this case, this can affect the sales of a lot of other product sold to other customers.  And if these customers made product, then we can expect cascading recalls to occur.

It is a dog-eat-dog...scratch that....a dog-eat-human food world...
