CDC Reports on a 2016 Salmonella Outbreak Related to Peppers

CDC released a report detailing a 2016 Salmonella outbreak related to peppers.  This is the first time this report has been issued.  Investigators had difficulties in determining the type of pepper as well as the source of the pepper.  Because the lack of 'actionable' information, no warning was issued to consumers.

In June 2016, PulseNet identified a cluster of 16 Salmonella Anatum infections with an indistinguishable [unique] pulsed-field gel electrophoresis (PFGE) pattern from four states.  Thirty-two patients in nine states were identified with illness onsets from May 6–July 9, 2016.  The combined evidence indicated that fresh hot peppers were the likely source of infection; however, a single pepper type or source farm was not identified.  Much of this related to different foods people ate, whether specific peppers were included in salsa recipes, etc.   The only link was related to testing in in April 2016, the same PFGE pattern had been uploaded to PulseNet from an isolate obtained from an Anaheim pepper, a mild to medium hot pepper.

This demonstrates the challenges posed by our food system, especially for produce items like peppers that are used primarily as an ingredient in many different foods, such as salsa.  Cross contamination from the peppers to other items may muddy the investigation.

USDA ERS Publishes Food Safety Costs for Produce Operations Complying to Increased Food Safety Standards (LGMA)

The USDA Economic Research Service released a 64 page report on the costs associated with meeting safety standards established by the California Leafy Greens Marketing Agreement (LGMA).  The costs with the LGMA should be similar to what will be required by the FSMA Produce Safety Rule.  This is based upon 7 produce operations and was conducted in 2012.

The paper acknowledged that it is difficult to assess the costs, and thus come up with average cost/farm or cost/acre for compliance.  They were able to determine where those costs went on average:

• food safety staff - 38%
• foremen food safety time - 32% 
• audits - 17%
• lost product due to animal intrusion - 11%
• water testing - 2%
• Other costs not uniformly collected included harvest worker training, glove use, raw product testing, and external record keeping management systems.

Estimated costs for foreman (based upon time allocation) ranged from 80,000 to 1,012,000 million.

Firms averaged

and services

Note: In reporting individual costs per firm, there is a mix of costs for different-sized operations, and also a mix of costs for leafy greens and the whole produce operation. The  combination of firms reporting data for any cost also varies. As a result, the numbers in table 3 cannot be added together to get a low and a high for all costs. Source: USDA, Economic Research Service.

How solid are these costs?  Good question.  They are based upon interviews...so if you ask someone what they are spending on mandated oversight....there may be a tendency to look at worst case scenario. Plus were there savings from improved practices?...hard to say.  I believe these costs increases are there, especially compared to processing facilities that already have much of the infrastructure in place.

Salmonella Outbreak in Canada Associated with Raw Frozen Breaded Chicken

In Canada, there have been 7 cases of Salmonella linked to frozen raw breaded chicken products.

Over the past few years, we have seen Salmonella outbreaks associated with raw breaded chicken (1, 2, 3 ).  In fact, FSIS issued an alert after the the Aspen Foods Salmonella-in-breaded chicken outbreak.   As was pointed out each time, there are a few issues - 1) the product is frozen, so when the consumer begins with frozen product, they may not cook it long enough in order to achieve the proper internal temperature. Along with this, many people do not use a thermometer in order to ensure that temperature is met, and  2) breaded products often look like they are fully cooked. This is because the par-cooking that sets the breading gives it a finished cooked appearance.  

So even though companies may post cooking instructions on the package, there must be controls in place to limit, even to the point of elimination, the risk of Salmonella.  This includes controlling Salmonella in the process environment, preventing growth through tight temperature control, and par-frying it well.

Executives of Egg Company Ordered to Begin Serving Sentences for 2010 Salmonella Outbreak

A father and son, owners of an Iowa egg company, have been mandated to report to prison.  They were found guilty in 2014 to the 2010 Salmonella outbreak associated with eggs where close to 2000 people became infected.  They appealed their sentences, but those were upheld.

According to the news release, business groups had supported the appeal, arguing "that it is unfair to send corporate executives to prison for violations that they were either unaware of or that were committed by subordinates. The groups said it's highly unusual to attach a criminal penalty and prison time to executives when there is no proof of intention or knowledge of wrongdoing."  If you believe that food safety starts at the top, which I do, then it is important the executives should not only be aware, but also support food safety.

US Stops Imported Beef from Brazil for Food Safety Concerns

The US has stopped all importation of fresh beef from Brazil for food safety concerns.  Brazil is the fifth largest exporter of beef to the US.  Since an investigation into the Brazilian meat industry in March, the US has been inspecting all meat products from that country, refusing 11% of those shipments due to "public health concerns, sanitary conditions, and animal health issues."

Drain Decontamination Using Chlorine Dioxide Pods

Our good friend Dr. Mark Berrang shared his recent research on decontaminating floor drains with chlorine dioxide pods.  This may be useful for many facilities beyond the poultry processing facilities where the research was conducted, especially those facilities that have problems with drain backups. This method was able to achieve a 8.7 log reduction in the drain water and 6.7 log reduction of cells attached to drain piping.

Contact me if you want a copy of the paper or the supplier contact used in this research. (we of course, are not endorsing any one supplier).

NY Nut and Fruit Processor Source of Listeria Related Recalls

Over the past several days, many of the listeria - nut/dried fruit recalls have been linked to a company called HVF, Inc. AKA - Hudson Valley Farms. This includes the recent hummus recall due to pine nuts from HVF as well as other recalls such as protein bars from GoMarco, granola products from New England Bakers, and Protein Bars and Bits from Bulletproof 360. It is hard to tell what the ultimate source of these recalls, but clearly HVF is a major link, if not the primary source.

Here again is what appears to be an ingredient supply issue that triggers recalls among a number of further processing facilities.  In this case, the ingredient was produced by a very small processing facility - what kind of supplier controls were in place?  How legitimate is this supplier?

One concern was that the supplier information was not readily available online.  No website was present - was it there and taken down, or was there never one to start?  Wouldn't it be better to have a supplier who is there when there is an issue and to state the nature of the issue on their website?

It was difficult to tell the scope of the operation. According to a story in the Miami Herald, HVF is a company of 10 people or less. Looking further, it appears to be part of a larger group with the parent appearing to be a company called Bedemco, an importer of nut and fruit products.  HVF may just be a packing facility for this family run company.
