Update on Listeria Outbreak Associated with Salad

CDC provided an update on the number of listeriosis cases linked to Dole's packaged salads.  There are now 15 cases and 1 death.  Dole has shut down its Ohio processing facility and does not plan to restart until at least February.   With regard to impacted product, Dole initially called its action a voluntary withdrawal.  It changed that status to a voluntary recall on January 27th.

CDC Update - Salmonella Cases Associated with Cucumbers Continue to Trickle In

 Since CDC's last report in November, 50 more people from 16 states have been reported becoming ill with a specific strain of Salmonella associated with cucumbers from one distributor in California.  The current total is 888 cases in 39 states. 

Food safety requires the pessimism of intelligence and the optimism of will

This is based off a quote in the Independent from Donald Rumsfeld, the former US Defense Secretary,    “As my friend Andre de Staercke once put it to me, “What one needs in life are the pessimism of intelligence and the optimism of will.”. I thought this statement was even more applicable to food safety and the duties of the food industry professional with responsibilities for food safety.
Food safety requires the pessimism of intelligence and the optimism of will.
The challenges for food safety occur all the time - whether it is RTE product being run in a facility that was built long before there was consideration for organisms like Listeria, or the company's marketing guru pushing a more natural / minimally processed product to be sold as fresh refrigerated, or a restaurant entrepreneur wishing to produce a vacuum packaged, fully cooked meal.  For the person tasked with ensuring the safety of products, they must recognize the risks and apply sound judgment based upon scientific facts or historical reports of past outbreaks or recalls.  Then they must either be willing to apply necessary controls to prevent those risks or squash poorly designed, high risk projects before excessive investments are made.  The force of will comes from knowing that in the end, that customers will not harmed, and with that, the company's future is more secure.

Depending upon the company's culture, the food safety professional has often been looked at as the naysayer or worrywart.  But with numerous examples of food safety issues where food safety issues have cost company's lost millions, or in some cases, resulted in executives being sentenced to jail time, the food safety professional's job is becoming more valued.

Pizza Recalled for Mistaking Pork Pepperoni for Beef Pepperoni

Whole Foods is recalling over 70,000lbs of pepperoni pizza because instead of using beef pepperoni, which is stated on the label, they used pepperoni made from pork.  According to the FSIS Notice - "The problem was discovered by FSIS during a label review at the establishment and occurred as a result of a change in ingredient suppliers."

One item of note is that this occurred during a supplier change.....a purchasing issue.  Second is that this should have been identified during the inspection of incoming materials, specifically the evaluation of the label.

There were two other recalls within the past few days where pork was included in a product where it was not on the label.  One was a ravioli product and the other was knockwurst.

Whole Foods Recalls Frozen Pizza Products Due to Misbranding
Class II Recall 010-2016
Health Risk: Low Jan 25, 2016

Congressional and Public Affairs   Richard J. McIntire  (202) 720-9113 

WASHINGTON, Jan. 25, 2016 – Whole Foods/North Atlantic Kitchens, an Everett, Mass. establishment, is recalling approximately 73,898 pounds of pepperoni pizza products due to misbranding, the U.S. Department of Agriculture’s Food Safety and Inspection Service (FSIS) announced today. The product is labeled as containing uncured beef pepperoni. However, the pizzas contain uncured pork pepperoni, which is not declared on the product label. Some individuals have a sensitivity or intolerance to pork.

Concern for Zika Virus - Mosquito transmitted disease of South and Central America

The Zika virus is a growing concern as it spreads throughout South and Central America as well as the Pacific Islands.  The mosquito is the primary vector.  While for most people, the symptoms of the viral infection are mild , there is a concern for pregnant women who become infected in that it may lead to microcephaly, a rare neurological condition in which an infant's head is significantly smaller which is associated with incomplete brain development.  Yikes.  (But this has not yet been totally proven.)

Cases of infection in the US have been seen in those who have traveled to areas where the virus is present.

Damn mosquitos...West Nile Virus was bad enough, now we got something else to worry about.  Mosquitos also carry other diseases including Chikungunya, dengue, yellow fever and malaria.

Zika Virus
 
Zika virus is spread to people through mosquito bites. The most common symptoms of Zika virus disease are fever, rash, joint pain, and conjunctivitis (red eyes). The illness is usually mild with symptoms lasting from several days to a week. Severe disease requiring hospitalization is uncommon.
 
Outbreaks of Zika have occurred in areas of Africa, Southeast Asia, the Pacific Islands, and the Americas. Because the Aedes species mosquitoes that spread Zika virus are found throughout the world, it is likely that outbreaks will spread to new countries. In December 2015, Puerto Rico reported its first confirmed Zika virus case. Locally transmitted Zika has not been reported elsewhere in the United States, but cases of Zika have been reported in returning travelers.

Dole Withdrawals Salad Items Linked to Listeria Outbreak

Dole is conducting a voluntary withdrawal of salad products made in their Springfield, OH facility after being linked to a Listeria outbreak.  In this outbreak, 12 people have been infected with one death.  

According to the CDC, the evidence indicates that packaged salads produced at the Dole processing facility in Springfield, Ohio  are the likely source.   From the CDC report:
  • Five (100%) of the five ill people who were asked about packaged salad reported eating packaged salad in the month before becoming ill. Two (100%) of two ill people who specified a brand of packaged salad reported eating various varieties of Dole brand packaged salads. 
  • The Ohio Department of Agriculture collected a Dole brand Field Greens packaged salad from a retail location and isolated Listeria. Laboratory tests showed that the Listeria isolate from the packaged salad was highly related genetically to isolates from ill people. This packaged salad was produced at the Springfield, Ohio Dole processing facility.
 CDC began investigating this in September of 2015, but as can be seen, there has been only a few cases coming in at a time, making the investigation process more difficult with providing a specific source.

At this point, it is difficult to comment too much without knowing more information.  Did the plant have an active Listeria control program?  Was it comprehensive in terms of evaluating washing systems and food contact surfaces including buildup/biofilms in those washing systems.  In many facilities, there is a focus on noncontact surfaces (zones 2 and 3) and conducting of preoperational samples rather than operational, but if there was indeed an issue in the process, would it have been identified if the facility was not looking deeper?  Did they know that they had an issue?

Taking a Cruise - Decreasing Risk of Becoming Sick

The CDC study recently published showed that the rates of diarrheal illness have decreased from 27.2 cases per 100,000 travel days in 2008 to 22.3 in 2014.  The most common agent was Norovirus.

Much of this is due to increase diligence of cruise ship operators.  "Fewer and less severe outbreaks are likely the result of earlier detection of acute gastroenteritis, along with cruise industry efforts to identify and control outbreaks by developing and implementing required Outbreak Prevention and Response Plans (4), using processes and chemical disinfectants known to be effective against a norovirus surrogate and proactively seeking strategies to limit acute gastroenteritis spread, using the most currently available evidence."
