Marler Listeria Blog

The USDA announced that 18th Street Deli Inc., a Hamtramck, Mich., establishment, is recalling approximately 118 pounds of julienne salad products with turkey, ham and hard-boiled eggs. The salads contain eggs that are the subject of an FDA recall due to contamination with Listeria monocytogenes.

E.coli O104 Strikes Again

Food Safety News

A group of French tourists returned home from Turkey last autumn with diarrheal illnesses, and two of them developed a life-threatening kidney disease linked to the foodborne pathogen E. coli.

Now French health officials have completed an investigation into this illness cluster and say the two women were infected with a strain of E. coli similar to the rarely seen bacteria that caused the devastating European outbreak linked to sprouts grown from Egyptian fenugreek seeds.
 
And they conclude this is “further evidence” that Shiga toxin-producing E. coli (STEC) serogroup O104 circulates in Turkey, along with Afghanistan, Egypt and Tunisia. “Public health authorities and clinicians should be vigilant for possible STEC O104 infection in individuals returning from these areas who present with post-diarrhoeal HUS,” the article advises.

EFSA – Scientific Opinion on Norovirus

EFSA

NoV is highly infectious, and there is no threshold infectivity limit for NoV detected by PCR. The probability of becoming infected increases with the dose but depends also on the characteristics of the organism, the food matrix and the host factors. The relationship between the number of infectious virus particles and the number of virus genome copies detected by quantitative PCR is not a constant, and it is important to realise that the infectious risk associated with low level positive oysters as determined by real-time PCR may be overestimated.

Quantitative data on viral load from areas compliant with current EU legislative requirements (E. coli standards) during January-March 2010 in 3 selected member states, show that a viral limit of 100, 200, 500, 1000 or 10.000 NoV PCR copies would result in 33.6-88.9%, 24.4-83.3%, 10.0-72.2%, 7.7-44.4% or 0-11.1% of non-compliant batches, respectively. Compliance with any of the above NoV limits would reduce the number of contaminated oysters placed on the market and therefore the risk for consumers to become infected. It is currently not possible to quantify the public health impact of different limits.

Microbiological criteria for NoV in oysters are useful for validation and verification of HACCP-based processes and procedures, and can also be used by competent authorities as an additional control to improve risk management in production areas, during processing and retail. The Panel recommended that risk managers should consider establishing an acceptable limit for NoV in oysters to be harvested and placed on the market. NoV testing of oysters (standardized CEN method) should be used to verify compliance with the acceptable NoV limit established.

The most effective public health measure to control human NoV infection from oyster consumption is to produce oysters from areas which are not faecally contaminated, particularly given the ineffectiveness of current depuration and relaying procedures.

FDA – Mock Salt Recall – Salmonella

FDA

It is quite interesting to see where pathogenic organisms can be found, I spend quite some time telling clients to be aware of control statements such as organisms will not grow below this pH, Temperature, aW etc. There is always a difference between growth and persistence and the organisms do not always know about the limits and tolerance they are supposed to have.

January 23, 2012 – University Place, Washington- Jones’ Seasoning Blends LLC announced a voluntary recall of Jones’ Mock Salt Original as well as Jones’ Mock Salt Spicy Southwest Blend due to the potential contamination of Salmonella.

No illnesses have been reported to date in connection with this voluntary recall.
