E. coli O157:H7 Outbreak Linked to Cucumbers (Colorado, 2013)

A 2013 outbreak of  E. coli O157:H7, where 9 individuals were infected, appears to be linked to eating sandwiches containing cucumbers.  All ill patrons ate at different shops of the same restaurant chain which all used the same lot of cucumbers.

From the report:


Prior to this outbreak, there have been no documented E. coli O157:H7 outbreaks associated with cucumbers in the United States, per a literature search conducted by CDPHE and by searching for outbreaks on CDC’s Foodborne Outbreak Online Database (http://wwwn.cdc.gov/foodborneoutbreaks/), which captures foodborne outbreak reports generated by local and state health departments and the CDC from 1998 through 2012. An outbreak of E. coli O157:H7 associated with consumption of cucumber salad (consisting of cucumbers, hard-boiled egg, and vinaigrette dressing) affected school-age children from England who were visiting France in 2002 (5). The investigators hypothesized that the cucumbers became contaminated in the growing field. There is evidence that cucumbers can support the growth of E. coli O157:H7 based on a 1993 study by Abdul-Raouf et al (6). The researchers inoculated sliced cucumbers with E. coli O157:H7 and found that the bacteria load increased when storage temperatures were at 21 degrees Celcius (69.8 degrees Fahrenheit). Mukherjee et al conducted microbiological analyses of fresh cucumbers produced by organic and conventional farmers in Minnesota and were not able to isolate E. coli O157:H7 but did find that cucumbers are often contaminated with coliforms, an indicator of fecal contamination (7).

For this particular investigation, it is not clear how the cucumbers could have been contaminated. It is very unlikely that contamination occurred within the 3 implicated Jimmy John’s locations, as no major food handling violations were noted during the environmental assessments and no ill food handlers were discovered. It is more likely that the implicated stores received contaminated cucumbers. Our investigation found no evidence that would support that the cucumbers became contaminated at the Denver-based produce distributor (Colo-Pac Produce, Inc.) or during shipment to the implicated Jimmy John’s locations. 


But it is easy to see that cucumbers can be a source. They are on the ground when harvested, and if not washed sufficiently, that contamination can be transferred to the slice when cut.

 Outbreak #2013-00-006 - Escherichia coli O157:H7 Outbreak Associated with Cucumbers Consumed at a Sandwich Restaurant Chain – Colorado, October 2013

Summary
 CDPHE and several Denver metropolitan area public health departments investigated an outbreak of Escherichia coli O157:H7 (E. coli O157:H7) that occurred in October 2013. Nine cases were identified, including 1 probable case and 8 laboratory-confirmed cases with matching pulsed-field gel electrophoresis (PFGE) and multiple-locus variable number tandem repeat analysis (MLVA) patterns from E. coli O157:H7 isolated from stool. All 9 cases reported eating sandwiches at Denver-area Jimmy John’s locations in early October 2013. The outbreak investigation consisted of case finding and interviews, 2 separate case-control studies, environmental investigations, produce traceback, and laboratory testing. The results of this investigation indicate that consumption of Jimmy John’s sandwiches containing cucumbers imported from Mexico was the likely cause of the outbreak. To our knowledge, this is the first E. coli O157:H7 outbreak associated with cucumbers reported in the United States. Public health and food safety officials should be aware that cucumbers may be contaminated with E. coli O157:H7, which could cause sporadic E. coli O157:H7 infections as well as outbreaks. As of the date of this report, no other cases of E. coli O157:H7 with the PFGE pattern combination seen in this outbreak were reported in Colorado.

Yogurt Recall - FDA Claims State Inspectors Knew of Issue Prior to Recall

Last year, Chobani recalled yogurt due to extensive mold contamination. The recall was issued after numerous consumer complaints.  According to the FDA Inspection report (page 6 if you really want to see), the Idaho Department of Agriculture knew about the mold issue 2 months before the recall.   Idaho DofA denies this claim.

State Knew Chobani Yogurt was Tainted Months before Recall, FDA Says


December 05, 2013 2:00 am • By Joe Cadotte - jcadotte@magicvalley.com

TWIN FALLS • The Idaho Department of Agriculture saw moldy yogurt during a routine inspection at Chobani two months before the company issued a voluntary recall, says a U.S. Food and Drug Administration report obtained by the Times-News under a Freedom of Information Act request.

The state denies the FDA claim.

Virginia Company Issues 2nd Recall for Sprouts Due to Listeria

A Virginia company is issuing another recall after the Virginia Department of Agriculture and Consumer Services found Listeria in the samples they had tested.  This is the 2nd recall for this company, the other recall occurring in 2012.

Courtesy Virginia Department of AgriculturePositive tests for listeria in fresh sprouts from Henry's Farm, Woodford, Va., spurred recalls in April 2012 and November this year. A warning letter from FDA states the labels on the packages violate federal law.

Frozen Enchiladas Recalled Due to Potential Of Salmonella Due to Cilantro Ingredient

A California Company is recalling their frozen chili cheese enchilada product due to the potential for Salmonella.  The recall came after the supplier of the organic cilantro ingredient used in the product notified the producer that they had found Salmonella in their routine testing of the cilantro.

This frozen product appears to be cooked by the processor, at least partially.  Although we can't tell whether the cilantro was added before or after the thermal process.

Another item to notice is that the package has cooking instructions that direct the consumer to fully cook this product before consuming.  These process steps would help to lower the risk of Salmonella in the product, however, if an issue were to arise, then it be a disaster for the manufacturer.  The likelihood of under cooking by the consumer must also be taken into account.

Raw Sprouts Linked to Salmonella Outbreak, 87 in 11 States

Update - As of 12/2/14, CDC reports 87 cases in 11 states.

Raw bean sprouts have been linked to 63 cases of Salmonella Enteritidis infection.  The bean sprout product was produced by Wonton Foods, based in Brooklyn, NY.  According to CDC, about 1/4 of those infected have been hospitalized.  The cases have been seen in 10 states, mostly in the Northeast and New England.
 
Bean and seed sprouts are considered high risk food items.  While beans and seeds are normally sanitized prior to beginning the sprouting process, any remaining pathogens on the beans or seeds, such as Salmonella or STEC E. coli, can grow under the conditions that are used to allow the beans or seeds to sprout and grow.
 
There have been a large number of outbreaks related to sprouts (clover sprouts and E. coli - June, 2014bean sprouts and E. coli, 2011sprouts and Salmonella, 2011 to name just a few).
No recall was conducted because the product was past the shelf-life date.

Controversy Over the Safety of Reusable Food Containers

 A battle has begun between the corrugated container provides and the reusable plastic container (RPC) providers with regard to safety for handling produce.  The corrugated container people cite two studies (that they paid for) that show contains can carry bacteria, while the RPC cite a history of use where there has been no documented cases of food safety issues related to these reusable plastic containers.

I guess my approach is more simplistic.  If food surfaces are contaminated, they can be the source of contamination to the food the carry.  That contamination can be pathogens or even spoilage organisms depending upon the application.  So if you are willing to properly clean those containers, then that is great, but you better be able to validate that cleaning process.  If not, there is the possibility of issues (depending on the application of use).  Or you can consider using one-time-use corrugated containers that eliminate the risk.

 Having worked in the industry for many years, I have seen reusable plastic containers that are down right disgusting.  And I think the RPC industry is doing itself a disservice by not stating that these containers need to be properly cleaned and sanitized, especially in applications where that contamination can be harmful (for example, in refrigerated RTE applications where Listeria biofilm formation can lead to contamination).

In a world where sustainability is becoming a necessity, reusable containers will become an important part for reducing waste.  But we cannot give those containers a pass because they are considered 'more sustainable'.  For operations that wish to go in this direction, part of that investment must be the means for cleaning and sanitizing.

Even done to the consumer level where people have used reusable plastic containers for storing food.  One company is selling reusable zip lock bags (bottom).  That is great, as long as the consumers can adequately clean them.

RPC, corrugated groups spar over food safety

11/19/2014 11:56:00 AM
Tom Karst 

Two recent studies of bacteria on reusable plastic containers — both sponsored by corrugated carton groups — question the cleaning process used on RPCs before they enter the supply chain again. RPC supplier IFCO and the Reusable Packaging Association has countered that no foodborne illness outbreak has been traced to RPCS. Keith Warriner, professor of food safety at the University of Guelph in Ontario, Canada, said the study of RPCs — commissioned by the Canadian Corrugated and Containerboard Association — was an extension of one he performed in 2013. The first study tested 50 RPCs, while the 2014 study involved 160 RPCs. In the 2014 study, RPC samples from five Canadian packing facilities were pulled from different lots of trays that had been delivered on pallets wrapped with plastic film. Corrugated cartons from those facilities were not tested for comparison, Warriner said.
