Homemade Mexican-style cheese results in numerous cases of salmonellosis

There appears to be a Salmonella outbreak in Illinois from what we would call 'homemade'  or 'black market' Mexican-style cheese.   The cheese is unlabeled and is sold in the untraditional channels...aka street vendors, workplace associates, back streets, etc....

You know the commercial......
Don't buy unlabeled cheese from a back alley vendor named Al  and wind up praying for death while lying on cold bathroom floor tile.

Health officials: Salmonella linked to unlabeled Mexican-style cheese
BY JORDAN OWEN Staff Reporter March 27, 2014 3:26PM



Updated: March 27, 2014 3:32PM

The Illinois Department of Public Health issued a warning Thursday, saying 100 people have contracted salmonella linked to illegally manufactured Mexican-style cheeses.

Health departments in Cook, DuPage, Boone, Fayette, Kane, Lake, LaSalle, Macon, Marion, McHenry, Vermillion, Washington and Will counties have reported about 100 cases of salmonella believed to be associated with the cheese since July 2012, according to a statement from the department.

IDPH is working to identify the manufacturer of the contaminated cheese, according to the department.

Many cases have reported consuming Mexican-style cheese obtained from worksites, including factories, and at train stations, from street vendors and from relatives and friends, the department said. The cheese is not labeled and is often wrapped in aluminum foil.

Canadian company recalls cheesy bread due to Listeria

A Canadian company is recalling breaded items with cheese after the product was found to have Listeria.  There have been no  illnesses associated with the bread items.

This is an interesting case because it is rare that we find a bread item with microbiological pathogen issues, especially Listeria.   However, since this is a bread item with cheese, this is what makes it different than regular bread.  Being that the Canadian recall notice is chock full  of information...not really, we can only guess how the issue occurred.  From looking at the pic, it appears the bread was cooked, sliced, and then layered with cheese.  Then, to fix the cheese to the top of the bread, it was surface heated to a point where the cheese sticks on the bread but the bread is not reheated.   So if this is the case, either the cheese was contaminated before application (either as an incoming ingredient or by the application equipment) and then the organism survived because the fixing heat was no sufficient heat to destroy the organism.  If the cheese did receive sufficient heat, then there could have been a post-process contamination event where the cheese, now on the bread, was exposed to Listeria within the environment.  Perhaps the cheese wasn't heated at all, and was just added to warm bread, making the contamination event easier to  explain.


It is hard to see this as a high risk product from the standpoint that one would expect the water activity (Aw) or available moisture of the cheese to be high enough to support growth.
One question was whether this was frozen or refrigerated?  Freezing will prevent growth of Listeria and would also mean the product would have to probably be heated before eating.  Refrigerated cheesy bread would allow growth, but would also have a limited shelf-life.  
How did they find the contamination...were they testing, and if so, why?
Would love to hear any feedback on this one.

This has implications for retail and foodservice operations who make similar breaded products (or even RTE refrigerated pizza), store it and then sell it

Minnesota Company Recalls Refrigerated Products Due to Listeria

Parkers Farm, a Minnesota company, is recalling a number of refrigerated products, including peanut butter, cheese, salsa, and spreads, after some of the product tested positive for Listeria. No illnesses have been reported.

According to the FDA recall notice, products are distributed nationwide under the Parkers Farm, Parkers, Happy Farms, Central Markets, Hy-Top, Amish Classic, Say Cheez, Win Schuler, and Bucky Badger labels. These products were sold at several retail stores including but not limited to Hy-Vee, Cub, Rainbow, Byerly’s, Lunds, Target, Whole Foods, Price Chopper, Nash Finch, Costco, ALDI, Wal-Mart, and Brookshire stores.

What we can surmise: the company produced a line of refrigerated products including peanut butter – yes, refrigerated peanut butter, and cheese spreads. While it could be expected that Listeria would not grow in peanut butter because of low water activity (Aw), peanut butter could have become contaminated if that product was produced using shared equipment (that was not properly cleaned) or through bad handling and processing practices that led cross contamination. One would guess that the cheese spreads would also be unlikely to support the growth of Listeria (low Aw) and the same could be guessed about the salsa (low pH). But Listeria could be brought into the facility from the ingredients used to make the cheese products, or through other means, and then survived in a niche within the processing environment, especially f there was build-up of residual cheese ‘stuff’ in the processing environment or on the equipment. This notion is supported by the fact that this is the second recall due to Listeria (the last in 2010….of course this begs the question to what degree was the company putting the effort towards control).

It would be interesting to see if this was the same Listeria strain found in both recalls. I would be willing to bet it is the same strain. Work done at Penn State has shown Listeria’s ability to form a resistant state that can survive for long periods of time. In other recall situations, whole genome sequencing has verified that the same organism, outside of a few changes of base pairs in the whole genome, can re-emerge after years within that same processing environment.

So while none of the finished products may be viewed as risky for the growth of Listeria (due to low Aw or low pH), this does not preclude the organism from being present on the product. And here again, we have a scenario where a positive product test triggers a recall on what would probably be viewed as a lower risk product.

Florida company recalls fresh basil due to Salmonella

A Florida company is recalling packaged fresh basil for potential Salmonella contamination.  A product sample was found to positive for Salmonella during FDA routine random sample testing.  Additional product testing conducted at the request of the packer was negative.  The product was shipped to 7 states  in the southeast US and is distributed by Trader Joe's.  There have been no reported illnesses.

It is conceivable that the basil, which is grown outdoors, may come up with that random positive sample of Salmonella while subsequent sampling results are negative.  Decontamination after harvesting is difficult since the product is highly perishable.  Normally the consumer should wash it immediately before use, especially when used in fresh applications.

This is not the first time basil has been found to be positive for Salmonella.  In 2011, an Indiana company recalled basil after FDA testing found a positive sample.

Backyard chickens and the higher risk of Salmonella infection

Research published in Clinical Infectious Diseases (CID) discusses the increase trend of Salmonella cases related to chickens in kept and raised in the home environment or backyard.  Many of these chickens come from mail-order hatcheries.

People, most those who are new to owning chicken, do not realize the risk with regard to the higher prevalence of Salmonella.  People often treat chickens as pets, and this can be problematic  when people fail to wash their hands afterward.  This is especially a problem in young children who are more susceptible and less likely to wash their hands afterwards.

Abstract

Poultry are well recognized as possible carriers of Salmonella species. As part of the local foods movement, backyard poultry flocks have increased in popularity in recent years. Between 1996 and 2012, 45 outbreaks of human Salmonella infections linked to live poultry from mail-order hatcheries were documented. This review examines the history of live poultry–associated salmonellosis in humans in the United States, the current status of the issue, and what can be done to help prevent these illnesses. An integrated One Health approach involving the mail-order hatchery industry, feed stores, healthcare providers, veterinarians, and backyard flock owners is needed to help prevent live poultry–associated salmonellosis.

FDA Shuts Down Delaware Cheese Plant

FDA shut down the Roos Foods cheese plant, that had recently recalled product linked to a Listeria outbreak, after FDA found a number of findings in their investigation.
From the FDA report, the findings included:
  • the roof leaking so badly that water was raining down into the cheese processing room, including onto the cheese processing equipment and storage tanks;
  • standing water on the floor throughout the cheese curd processing room in proximity to the cheese vats and in the storage rooms;
  • metal roof/ceiling and metal supports exhibiting a rusted appearance with metal flaking precluding effective cleaning and sanitizing;
  • food residues found on equipment after cleaning had been performed;
  • openings to milk storage tanks and transfer piping were not capped to prevent contaminants from entering or contaminating food contact surfaces; and
  • floors, wall, and equipment that were deteriorated and in bad repair, including processing equipment and storage vats with rust holes and floors with rough concrete deterioration.
 
The conditions found in the inspection were sure issues for Listeria contamination....leaks contributing to excessive moisture into the processing environment and being a source of contamination, poor cleaning practices that allow for growth of Listeria within that environment, poor operating equipment that allows access of that contamination to the product, and finally the facility was in bad condition which prevented that contamination from being removed.  The
 
In short, Listeria contamination had access into the facility and to the product, the conditions within the plant supported growth of the organism and bad facility conditions prevented good cleanup.
 
It is also important to note that this is the second time that FDA used its new powers granted by FSMA to remove a facilities registration and thus shut down that facility.  The first case was the peanut butter facility that had Salmonella contamination.  After about a number of months of working with FDA, that peanut butter facility ended up closing for good.  If this is an indication, this cheese facility will have a long road to get to the point of reopening, if they survive at all.

FDA News Release
FDA Investigates presence of Listeria in some Hispanic-style Cheeses
Posted March 12, 2014 
 UPDATE
The FDA suspended the food facility registration of Roos Foods Inc.2 of Kenton Delaware on March 11, 2014 after the FDA determined there was a reasonable probability of food manufactured, processed, packed, or held by Roos Foods causing serious adverse health consequences or death to humans.
The FDA ordered the suspension after an investigation by the FDA, Centers for Disease Control and Prevention, and state and local partners linked a multi-state outbreak of listeriosis to cheeses found to be contaminated with Listeria monocytogenes and manufactured by the company. Food facility registration is required for any facility engaged in manufacturing, processing, packing, or holding food for consumption in the United States, and if the registration of a facility is suspended, no person shall introduce food from such facility into interstate or intrastate commerce in the United States. The FDA inspected the company’s facility from February 18 – March 4, 2014. During the inspection, FDA investigators found insanitary conditions including:
  • the roof leaking so badly that water was raining down into the cheese processing room, including onto the cheese processing equipment and storage tanks;
  • standing water on the floor throughout the cheese curd processing room in proximity to the cheese vats and in the storage rooms;
  • metal roof/ceiling and metal supports exhibiting a rusted appearance with metal flaking precluding effective cleaning and sanitizing;
  • food residues found on equipment after cleaning had been performed;
  • openings to milk storage tanks and transfer piping were not capped to prevent contaminants from entering or contaminating food contact surfaces; and
  • floors, wall, and equipment that were deteriorated and in bad repair, including processing equipment and storage vats with rust holes and floors with rough concrete deterioration.
Additionally, the FDA collected environmental samples from different areas of the facility, including the cheese processing room and various pieces of equipment. FDA's testing identified 12 swabs that tested positive for Listeria monocytogenes, and pulsed-field gel electrophoresis (PFGE) analysis showed that 11 of those swabs had the same Listeria monocytogenes "DNA-fingerprint" as the outbreak strain.
In response to evidence collected during the investigation by the FDA, CDC, and state officials, the state of Delaware’s Division of Public Health issued a Cease and Desist Production and Distribution order to the firm on February 28, 2014.
The FDA will vacate the suspension order and reinstate Roos Foods’ facility registration when the FDA determines that food manufactured, processed, packed, or held at the facility no longer has a reasonable probability of causing serious adverse health consequences or death to humans.
