CDC Report on Foodborne Illness Associated with Fish

Each year people become ill from eating contaminated fish.  CDC issued a report on data from their surveillance system on the agents and the types of fish in the period 1998 to 2015.  Table 2 from that report (ref below) provides a nice summary of those findings that link agent and the source of fish:

Scombrotoxin is the leading agent of foodborne illness associated with fish and it is found in tuna and mahi-mahi.  Scombrotoxin is due to histamine formation as a byproduct of microbial activity as that fish meat spoils when it is temperature abused.   The symptoms are similar to what you would have during an allergic reaction.  This toxin is not destroyed by heating.

Ciquatoxin is found associated with tropical predator fish such as grouper and barracuda when those fish eat smaller fish that have eaten a particular types of dinoflagellate (type of plankton).  The toxin bioaccumulates in the predator fish.  There are gastrointestinal issues, but the biggest issue are the neurological affects  that include headaches, muscle aches, numbness, and cold allodynia -  a burning sensation on contact with cold.  These symptoms can persist for weeks to months.  The toxin is heat stable.

Pew Releases Report on Making Meat and Poultry Safer

Pew Charitable Trusts, a non-profit organization dedicated to encourage responsive government and support scientific research on a wide range of issues including food safety, released a report on making meat and poultry safer.  A few of their recommendations:

• Government agencies should fund research into how to best manage herds or flocks to maintain animal health and keep harmful bacteria out, including the use of clean feed, vaccines, and prebiotics and probiotics.
• Regulatory agencies should provide incentives for the implementation of pre-harvest food safety interventions
• Industry should consider individual pre-harvest interventions within the larger context of managing the health of the herd or flock and implement adequate controls to protect animal health and keep pathogens out,
• All stakeholders should develop information technology infrastructure and capacity to encourage sharing of efficacy and safety data among industry, academia, governmental researchers, and regulatory agencies

Good for them.  Now just need some funding to make it more of this happen.

The full report can be found here.  Good reference information on pre-harvest interventions.

NY Establishment Recalls 7.2 Million Pounds of Hot Dog Product After Complaints of Bone Material

  A NY establishment is recalling approximately 7.2 million pounds of hot dog products after complaints of bone material were received.  This covers about 3.5 months of production.  According to the USDA recall notice, "The problem was discovered through FSIS’ Consumer Compliant Monitoring System (CCMS) on July 10, 2017. Complaints stated that extraneous material, specifically pieces of bone, were found within the product.    There has been one reported minor oral injury associated with consumption of this product. FSIS has received no additional reports of injury or illness from consumption of these products."

The brand of product, Sabrett, is sold in the locally in the NY area to deli's and foodservice operations, but in large part to street vending carts.

CDC Report - Two Outbreaks of Trichinosis Linked to Consumption of Walrus Meat

If you ever have the opportunity to eat walrus meat, make sure it is cooked well.  There were two recent outbreaks of trichinosis or trichinellosis (five cases each) in Alaska that were associated with consumption of walrus meat.  The disease is caused by the parasite trichinella and is acquired when the larvae of the worm in ingested when consuming contaminated meat of animals including bear, cougar, wild boar and walruses.  Domestic pigs were once a source, but not really any more since controls were put in place by the industry to improve farming conditions.

Initial infection leads to nausea, diarrhea, vomiting, fatigue, fever, and abdominal discomfort. This is followed within a few weeks by headaches, fevers, chills, cough, swelling of the face and eyes, aching joints and muscle pains, as the larvae get into the blood stream and start to encyst into the muscles.. "If the infection is heavy, patients may experience difficulty coordinating movements, and have heart and breathing problems. In severe cases, death can occur."

Cooking wild meat to an internal temperature of 160ºF will take care of the issue.  Canning wild meat is another alternative to consider.

CDC Report - 2016-2017 E.coli non-O157 Outbreak in Canada Associated with Flour

CDC issued a field note on the 2016-2017 E. coli non-O157 outbreak in Canada associated with flour.  In all, 29 people were infected in Canada and one in the US.   Robin Hood flour was the identified brand.  According to the report, "Eleven of these sixteen patients reported they ate or probably ate raw dough during their exposure period."  "Eight patients were hospitalized, and one developed hemolytic uremic syndrome. Clinical isolates were typed as E. coli O121:H19."

Energy Bars Recalled After Complaints of Nut Allergic Reactions

Clif Bar is recalling certain varieties of its energy bar products after receiving 'a small number' of consumer complaints of peanut or tree nut allergic reactions, although these were not confirmed.

This is the type of issue where good allergen verification records are needed.  Are there other products run in the facility with peanuts and tree nuts, and if so, were good sanitation and other allergen procedures followed.   What about supplier control?  Do any of the suppliers handle peanut and tree nuts that could have accidentally made their way into a non-nut ingredient.

Results of Sampling Retail Foods for Listeria

USDA led a multiyear study to look at Listeria in foods at retail.

• Six broad groups were tested - seafood, produce, dairy, meat, eggs, and combination foods) 
• Samples were collected weekly at large national chain supermarkets and independent grocery stores between December 2010 and March 2013.
• 27,389 total samples were taken with 
• 116 samples tested positive by the BAX PCR system for L. monocytogenes, and the pathogen was isolated and confirmed for 102 samples (0.3%)
• 571 samples that tested positive for Listeria-like organisms

A few takeaways

• Screening samples used a 25 gram sample. If a larger sample size was used, would the percent positive be higher?
• Sampling ended over 4 years ago.  If sampling and testing were conduced today, would we expect lower numbers?
• Cut raw vegetables were the highest at 1%., but the scariest is the pre-made salads - seafood salad and deli-type salads (and pre-made sandwiches) since those would be consumed without any preparation and the numbers/gram were generally lower.
• While the percentage of cheese samples that were positive are low, there where some high numbers on those that tested positive.

Penn State Extension educators develop plan to educate plain sect on food safety

UNIVERSITY PARK, Pa. — Technology has changed the way we communicate and learn. Computers, video conferencing and online courses are just a few of the tools educators commonly use to impart knowledge.

But what if you normally use technology to teach but can't?

That was the challenge Penn State Extension food-safety educators like Jeff Stoltzfus, who is based in Lancaster County, faced earlier this year when asked to use today's technology to educate Amish and Mennonite farmer — some of whom reject modern ways — about new food-safety regulations.

Chicken Salad Recalled for Being Tuna Salad - Allergen Mislabeling

Whole Foods is recalling chicken salad product that contains...tuna salad.  While this mislabeling issue may seem small and easy to make, it is reason for a Class I recall due to undeclared allergens, in this case, fish in the product but not on the label.  The issue was discovered at store level as store employees were unpacking the product.

According to the report, this company had a similar issue in the past.  In January of 2017, they shipped egg salad labeled as chicken salad.  Again, this is a allergen mislabeling issue.  This would be where one would want to have an Allergen Preventive Control or a Critical Control Point to ensure the labels match the product produced.

It seems that Jessica Simpson made the same mistake...thinking Chicken of the Sea was chicken.  Don't be like Jessica Simpson, control your labels!
