Nacho Cheese Sauce Probable Source of Gas Station Botulism Cases

Public Health officials in CA believe the source of the botulism cases that occurred from eating at a gas station to be the nacho cheese sauce product.  Most cheese sauce products are made to be shelf-stable for distribution, but once opened, most products may need to be stored at the proper temperatures (outside of the temperature danger zone) to prevent growth. Much of this depends on the formulation (pH, Aw, preservatives).  They also have to be protected against cross contamination.

It difficult to tell whether these product were not properly formulated or were improperly held,  One could guess that the cheese sauce was not properly stored or handled after opening, allowing for a small amount of contamination to grow.  It may have been transferred from a pouch to a canister or serving trey.  For Clostridium botulinun, intoxication to occur, the organism would need to grow in number to produce sufficient toxin.  The product itself would need to be formulated to allow growth and that product would also need to be held at improper temperatures, most likely in the upper part of the temperature danger zone (70F to 125F).

With a thick product like this, people may assume it is like ketchup or mustard that can be left at room temperature after opening....not unless it was formulated that way.  Generally cheese sauce have a higher pH and Aw.   Another potential issue can occur if these products are modified in any way.  Adding peppers or other raw ingredients can be an issue.  Adding water to the product can also be an issue....such as might be the case if the product thickened up after sitting on the hot bar all day.

Canadian Firm Recalls Frozen Breaded Chicken Products for Potential Staph Aureus Enterotoxin

A Canadian firm is recalling breaded chicken products for Staphylococcus aureus enterotoxin.  Product was distributed in Ontario.  No illnesses have been reported.

The issue with Staphylococcus is that the organism  can grow in the batter if that batter is temperature abused.  As the organism grows to high numbers, it produced a heat stable toxin.  So once there, the fryer used to set the coasting at the manufacturing facility as well as any cooking done in the home by the consumer will not eliminate that toxin.. It is critical (thus a CCP / Process Preventive Control) for facilities to control batter temperature throughout the day.

Fresh Bagged Spinach Recalled for Listeria Contamination

Frozen Peas Recalled After Sample Tests Positive for Listeria

A Wisconsin frozen food company is recalling frozen peas after product was tested by the State of Florida and found to contain Listeria.

While we would expect that someone would cook frozen peas, which if done according to instructions, would eliminate Listeria, people may not always do that.  Or they may use them as raw in specific applications such as pea salad or in a smoothie.

RTE Burrito Products Recalled for Listeria Contamination.

A New Mexico food company is recalling 252,000 lbs of frozen burrito products after FSIS testing found a Listeria positive product sample.  The product is classified as a ready-to-eat product, and as a ready-to-eat product, the company would need to have an active Listeria control program.   With this much product recalled, it probably was not that 'active'.

The directions are heat-and-serve for both frozen and thawed product.

Home Delivered Meat - Buyer Beware

A recent study conducted by RU and TSU looks at issues involving meat shipped to homes via home delivery systems such as meal kits.   These issues include:

• A wide range of temperatures upon receipt, ranging from (-)23F to 75F.  Much of the issue was related to the type of coolant (dry ice best, gel packs worst) and the amount of insulating packaging material surrounding the product.
• Most home delivery companies did not require receipt upon delivery, which means that product can sit on the front porch until the home owner realizes it is there.  This can be an issue when the product is shipped as a surprise gift, so the recipient is not expecting it.
• Home delivery companies did not have food safety information on their website
• Products were not properly labeled to indicate the type of meat.
• Microbial loads varied greatly. Pathogen loads varied greatly.

The authors stated that the bigger, better known companies did a better job, but with many companies entering the business channel, there may be more concern.

In the end, buyer beware.

CDC Report - 2016 E.coli (STEC) Outbreak Linked to Stream Water Contaminated with Deer Feces

In May of 2016, 4 children became infected with Shiga toxin-producing E. coli (STEC) after playing in a stream in a city park.  After an investigation, the likely source was determined to be deer poop (aka scat).  According to the report, "MLVA profiles were identical for the case-patient, water, and deer scat isolates".

The presence of E. coli in the water varied over time. Coyote scat also had E. coli of similar makeup..but this may be related to the fact the coyote is drinking that same water.  What this does show is that surface water is prone to contamination from animal feces and this contamination can be passed to humans directly through intake of that water or potentially through food irrigated with that water.

Contaminated Stream Water as Source for Escherichia coli O157 Illness in Children

Abstract

In May 2016, an outbreak of Shiga toxin–producing Escherichia coli O157 infections occurred among children who had played in a stream flowing through a park. Analysis of E. coli isolates from the patients, stream water, and deer and coyote scat showed that feces from deer were the most likely source of contamination.
