CDC Issues Warning About Vibrio in Crab Meat From Venezuela

CDC issued a news release about an outbreak of Vibrio parahaemolyticus linked to fresh Crab Meat imported from Venezuela. CDC warns consumers to avoid crab meat from Venezuela, including confirming that crab meat is not from there before consuming.   Twelve people infected with Vibrio parahaemolyticus who ate fresh crab meat have been reported from Maryland, Louisiana, Pennsylvania, and the District of Columbia.

Cooking food will destroy the organism, so illness occurs when seafood is eaten raw/undercooked or the product is recontaminated after cooking.

Vibrio parahaemolyticus is a Gram-negative, curve-shaped rod frequently isolated from the estuarine and marine environments of the United States and other tropical-to-temperate coastal areas, worldwide.  Cases are more often seen in the warmer months when the water temperature is greater than 15C (59F).  One study showed that Vibrio infections maybe increasing with global warming and rising water temperatures.

The symptoms of a Vibrio infection from contaminated food include watery diarrhea and the following signs and symptoms within 24 hours (4 to 90 hours) including stomach cramping, nausea, vomiting, fever.  Symptoms usually lasts about 3 days (2 to 6), and most people recover without treatment.  However the illness can lead to septicemia in susceptible people (diabetes, liver disease, kidney disease, cancer, AIDS, or other illnesses that result in an immunocompromised state, and those on immunosuppressive medications).

McDonalds Pulls Salads After Being Linked To Cyclospora Outbreak

McDonald's restaurants in the mid-west have pulled their salads after being linked to a large outbreak of Cyclospora.  This comes after last month's outbreak linked to Del Monte's trays of sliced vegetables.

The reference below lists some of the difficulties of this parasite...one is that it may be more resistant to sanitizers and the other is the ability to attach to produce.

So basically, the parasite gets into water used for irrigation.  The source being fecal contamination from someone who became ill.  Once on the crops, it may not be easy to get rid of it.

Not a lot is know about cyclospora, one of the issues being is that humans are the only known reservoir.  This makes studying using animal models impossible.

Update on Cyclospora cayetanensis, a Food-Borne and Waterborne Parasite
Yne´s R. Ortega* and Roxana Sanchez
University of Georgia, Center for Food Safety, Griffin, Georgia 30223-1797

"Individuals with Cyclospora infection excrete unsporulated oocysts in their feces (Fig. 1). These oocysts require 7 to 15 days to sporulate under ideal conditions (23 to 27°C) and presumably become infectious to a susceptible host. When food or water contaminated with infectious oocysts is ingested
by a susceptible host, the oocysts excyst and sporozoites are released to infect epithelial cells of the duodenum and jejunum."

"Cyclospora is highly resistant to disinfectants commonly used in food and water processing. This resistance may also be enhanced by the apparent higher binding affinities of the parasite for certain fresh produce. In the case of raspberries, which have been implicated in several outbreaks, the topography of the fruit is characterized by fine hair-like projections that facilitate the entrapment of the “sticky” Cyclospora oocysts. The microenvironment of the berry provides a favorable environment for parasite retention on the fruit. The stickiness of Cyclospora oocysts seems to be stronger than that of Cryptosporidium or Giardia oocysts. The adhesins responsible for this strong attachment to produce are unknown."

McDonald’s Salads Linked to Intestinal Parasite Outbreak in Midwest

Recalled Sugar Smacks Cereal Still on Shelf, Still Causing Illness

FDA released an update on the Salmonella outbreak associated with Kellogg's Honey Smacks Cereal.  Although a recall was issued in mid June, FDA learned that some retailers are still selling recalled product.  There are now 100 people in 33 states who have become ill.

The outbreak strain of Salmonella has been found in the contract manufacturing facility by FDA during their environmental swabbing analysis.  The facility has discontinued making product.

This cases demonstrates the difficulty in getting recalled product off the shelf, and with that, getting consumers to look in their pantry for recalled product.

Also of note is that this was contract manufactured product.  As a RTE product with post-leathality exposure (from the time it is extruded until it is packaged), environmental control is critical.  The fact that FDA was able to find Salmonella in the environment would indicate this this co-manufacturer's environmental program was not adequate.

This Week in Mislabeled Product for Week Ending July 14, 2018

Wrong Kind of Nuts - AZ is voluntarily recalling 148 units of the Superfood Salads due to misbranding and undeclared peanuts.  The product contains peanuts which are not declared on the product label as packages of peanuts were mistakenly included in the kits instead of cashews.

Food for thought: Eight tips for making good choices at farmers markets

June 28, 2018

UNIVERSITY PARK, Pa. — Traveling throughout Pennsylvania in the summer and fall, you don't have to go far to find a roadside stand or farmers market touting baskets of colorful fruits and vegetables.

However, as with any food purchase, a little know-how can go a long way in keeping you and your family safe from foodborne illness, advises a food safety educator with Penn State Extension.

"Farmers markets are undoubtedly an important — and historical — part of agriculture," said Sharon McDonald, senior extension educator and food safety specialist, when referring to the 310 markets in the state. "As these food venues continue to blossom – fueled by demand for locally grown and produced foods – so does the need to educate consumers about potential food safety hazards."

Raw Meat Cat Food Recalled Due to Pathogens

Radagast Pet Food, Inc. of Portland, OR is recalling raw cat food after internal testing found pathogens present on the product. 

  • Three lots of Rad Cat Raw Diet Free-Range Chicken Recipe because testing results indicate they have the potential to be contaminated with Listeria monocytogenes. 
  • One lot of Rad Cat Raw Diet Pasture-Raised Venison Recipe because testing results indicate it has the potential to be contaminated with Shiga Toxin producing E. coli O121. 
  • The Company discovered these lots were potentially contaminated during enhanced quality testing it conducted as a follow-up to its March 2018 recall.

As for the chicken, it appears the company is using HPP treated chicken as an ingredient.  While the HPP will reduce the level of pathogens associated with the raw chicken - Salmonella and Campylobacter,  the product is still subject to contamination after the bags are opened, mixed, and then packed.  The concern of course will be Listeria monocytogenes contamination as an environmental contaminate.

Venison meat is a risk for  STEC E. coli. Trim can be a concern and may be surface treated by the venison processor.  Even if so, not a guarantee to eliminate venison.

As with any raw pet food, there is the risk of pathogen contamination.  It would be best to consider using a HPP process on the finished product as a pathogen reduction step.  Instead, the company is relying on ingredient control as well as environmental control.  Monitoring is good for verification, but may not catch low level contamination.

EU - Frozen Vegetables Linked to Listeria Outbreak with Nine Deaths

In Europe, frozen vegetables, primarily corn, from a Hungarian processing facility have been linked to a Listeria outbreak where 47 have become infected including 9 deaths.

It appears that the same strain of Listeria has persisted in this plant for at least the last three years.

While corn has been the primary food associated with illness, it can be likely that more products are contaminated especially when similar equipment is used to pack the product.  Perhaps there was more of a tendency to under-cook the corn before eating or using frozen corn in ready-to-eat applications, such as using it in a salad or fresh salsa.
