Listeria Recalls - Could This Be the Story of Jason?

Within the week, there were two recalls, both involving Listeria contamination of cooked meat products that were discovered through testing. So luckily, no illnesses were reported. One is an FDA recall involving chicken salad sandwiches sold at retail. The other is a USDA recall involving meat strips that were sold in bulk to be used as ingredients.  

The process for both products would have entail post -process handling, so both would be at risk for Listeria contamination. The difference is that the sandwiches would be shipped refrigerated, allowing some time for growth to occur, although there is a limited shelf-life on the product. The other is a frozen product, so during the time that product is frozen, Listeria would not grow. The risk associated with this product would be impacted on how the further manufacturer used that product. Of course, if they further cook the product, perhaps as part of a BBQ meat product, it would eliminate the Listeria risk. However, if they made it into chicken salad and shipped it in a refrigerated state to retail stores, it would be similar to the FDA recalled product.

Once an operation has found they have a Listeria contamination issue, it is important that those companies do extensive cleaning and sanitizing that is verified by heavy monitoring. Too often, companies jump back into production without eliminating the true source of contamination. In some cases, they don’t find it in testing completed on non-production swabs and think they are good to go. However, once product starts to roll through the process, Listeria reemerges. The source of Listeria was hidden well within the bowls of the equipment, and only once product is flowing through for hours or even days, does the Listeria make its way back out onto the food contact surfaces and ultimately the product.  

Listeria is sort of like Jason, the scary dude in the hockey mask featured in in those horror movies. In this movie, after the screaming girl shoots him a zillion times and he falls off the two-story roof, the distraught girl, laying there for what seems to be an eternity, finally gets the nerve to look. However, looking down, she realizes Jason is not there on the ground. Slowly turning around, she screeches as she sees that Jason was standing right behind her with a machete in his hand. As you are watching the flick, you wonder, why did she not verify that he was dead sooner.  So yeah, Jason is like Listeria, you are just never able to kill it and he continues to scare the heck out of you. So don’t be the screaming girl, use a rocket-launcher instead of a handgun and check well and often that he is not standing behind you. And never assume he is really dead.



KNOTT'S FINE FOODS RECALLS CHICKEN SALAD SANDWICHES BECAUSE OF POSSIBLE HEALTH RISK
http://www.fda.gov/Safety/Recalls/ucm336282.htm?source=govdelivery

FOR IMMEDIATE RELEASE - January 21, 2013 - Knott's Fine Foods, Inc. of Paris, TN, is voluntarily recalling its 3 ounce Chicken Salad Sandwiches with an expiration date of 1/29/13 and earlier because they have the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.

New Food Safety Regulations Proposed for Fresh Produce Growers

Dr. LaBorde produced a very nice write-up on FSMA's proposed rule for produce safety.
 
New Food Safety Regulations Proposed for Fresh Produce Growers
 
Dr. Luke LaBorde, Department of Food Science, Penn State University 1/16/13
 
On January 4, 2013, the U.S. Food and Drug Administration (FDA) released a draft Produce Safety Rule as required under the Food Safety Modernization Act (FSMA) of 2011. This proposed regulation would establish mandatory practices that farmers must take to prevent microbial contamination of fresh produce. Below are highlights of requirements FDA would issue in the final regulation:
 
Worker Health and Hygiene - Farm and packing house workers who harvest or handle fresh produce, and their supervisors, must receive training on personnel hygiene and health conditions that can increase the risk for food contamination. Growers are required to show proof of training by keeping written records. Toilet facilities have to be readily accessible, kept reasonably clean, and supplied with toilet paper. Hand-washing stations must be close to toilet facilities and supplied with potable running water, hand soap, and clean single use towels.
 
Agricultural Water - Growers must be able to demonstrate that the water they use for irrigation, pesticide preparation, cooling and washing, etc. is safe for its intended use. Maximum average E. coli levels of 126 cells per 100 milliliters have been proposed for irrigation water that can contact the edible part of the crop. Water used for post harvest operations face more stringent standards; no detectable levels of E. coli are allowed.

FSMA Preventive Control Proposed Rule – Key Points for Food Processors


Official Title - Current Good Manufacturing Practice and Hazard Analysis and Risk-Based Preventive Controls for Human Food
http://www.fda.gov/Food/GuidanceRegulation/FSMA/ucm334115.htm

 There has been a lot of press regarding the FDA’s proposed rule on preventive controls. It has been hailed by many as a needed step for a safer food supply. If anything, it certainly helps to bring most every processor up to the same level in terms of HACCP based preventive measures.

The rule requires that FDA registered firms have a written food safety plan which is based upon HACCP principles.

For the food processor who has a HACCP plan in place and has undergone third party audits, there is nothing overwhelming within this rule. The challenge will be for those companies that do not have a HACCP system in place yet, (or a good plan in place). All companies who have registered their facility with the FDA, including those that do not ship out of state, may be subject to the FSMA preventive control rule. However, there are exemptions from the requirements for a Food Safety Plan for firms based upon size and whether they can be considered ‘on-farm’.

For firms with an active, functioning HACCP plan, the biggest thing to revise will be in the hazard analysis and the need to identify preventive controls. Preventive controls, as defined, can be CCPs or certain prerequisite programs that are needed to control potential hazards. Also, in addition to biological, chemical and physical hazards, we now include radiological hazards.

In current HACCP, the focus is on hazards controlled within the process by CCPs. In this, we acknowledge that prerequisite programs as making certain ‘hazards not likely to occur’. In the FSMA rule, all potential hazards must be addressed, and then for any considered reasonably likely to occur, the preventive control must be identified that renders the product safe (non-adulterated), whether that be a CCP or other program. In doing the hazard analysis, it will be important to include an assessment the severity of the illness or injury associated with the hazards.

Similar to what is done with CCPs, all preventive controls must have documented procedures. There must be monitoring, verification, and record keeping. However, unlike a CCP, there may not be a measurable parameter (critical limit). Validation for the preventive controls may not be needed (for sanitation and allergen control).

For example, one would need to identify sanitation as a preventive control for Listeria with a RTE food item when there is exposure of that product to the environment before packaging. They would need procedures for cleaning, verification that cleaning was done, and documentation to show this.

Facilities are required to have a written Recall Plan. At this time, there are no requirements for an environmental monitoring program, finished product testing, or supplier verification, although there is this with regard to process control (Proposed § 117.80(a)(5) would require that chemical, microbial, or extraneous-material testing procedures be used where necessary to identify sanitation failures or possible cross-contact and food contamination). FDA does ask for comments regarding the need of these being addressed. 

Food defense / intentional contamination will not be addressed in this rule.

Overall, FDA takes a less prescriptive approach with regard to the preventive control rule. While this gives processors opportunity to use a number of different methods to meet standard, it can be an issue when being inspected when that inspector doesn’t agree with that method. (We see that now with USDA inspectors with regard to validation…..’how do you know that process works’).

It is important to remember that this is just the proposed rule. This is the comment period and this closes on May 16th. At that time FDA will review and then reissue the rule, which then becomes implemented 60 days after being issued. Large firms will have one year to implement, small firms will have 2 years, and very small firms will have 3 years.

FDA Proposed Rules for Food Safety Plans and Produce Food Safety

On Friday, Januray 4, 2013, the FDA rolled out two proposed rules.
 
1) Current Good Manufacturing Practice and Hazard Analysis and Risk-Based Preventive Controls for Human Food 
  • Preventive Controls – applies to facility that manufacture, process, pack or hold food that fall under FDA jurisdiction. This rule requires that facilities have food safety plans in place for the preventive control of potential hazards, both within the process (HACCP) and those associated with the prerequisite programs. The document is 680 pages.
  • http://www.ofr.gov/OFRUpload/OFRData/2013-00125_PI.pdf
 
2) Standards for the Growing, Harvesting, Packing, and Holding of Produce for Human Consumption
 
Being proposed rules, there is a comment period before a final rule is issued. Then there will be a period of time from when the final rule is published until it is enacted

Trader Joe's Recalls Frozen Chicken Dinner Due to Listeria

Trader Joe’s is recalling a frozen chicken product, Butter Chicken with Basmati Rice after routine testing found the product was contaminated with Listeria. 240 cases were shipped to 14 eastern US states and DC. The product was made in Canada.

 The product is a frozen product and would be considered heat and serve (although a final temperature of 165ºF is listed as a temperature that should be reached before serving. http://onefoodguy.blogspot.com/2009/08/triumphant-return-of-tuesdays-tastings.html). Freezing will prevent the organism from growing, so the risk then comes down to the level of contamination to start and to what degree can we expect the heating to reduce that initial contamination. Of course, if a consumer puts the frozen product in the refrigerator for a few days before cooking, those Listeria levels could rise once the product thaws. Overall, it may not be a high risk, but a risk that the consumer probably does not want, and should not have to expect. Since this product was pre-cooked, the facility should be controlling Listeria in the post-process environment (after cooking through packaging).

 This is the second recall to hit the media in the last few months. The last was the Sunland peanut butter that was contaminated with Salmonella and resulted in 41 becoming infected. Trader Joe’s is a company that sources its products from food manufacturers and therefore must ensure that those suppliers have good food safety programs. Having two recalls does raise concern about the company’s sourcing program.

 

Nearly 5,000 pounds of Trader Joe's chicken and rice recalled

Martha Stewart, celebrity chef and author, contracts Salmonella


Martha Stewart contracted Salmonella over Thanksgiving from mishandling food in the form of raw turkey.  While we hate to see anyone become ill, having a celebrity chef come down with Salmonella can have a positive outcome.  Too often we see these celebrity chefs demonstrating poor practices, whether it is inadequate hand washing, cooking to the incorrect temperatures, or canning foods using the oven technique.  But my hope is that Martha will use this experience as motivator to endorse good safety practices.

Of course, in one of the news stories she has an idiot quote about a silver lining… “I lost some weight,”.  I can see it now, a bunch of kitchen debutantes licking raw chicken as a way to lose weight.  So much for my wishful thinking.

Salmonella: Martha Stewart Sickened Last Month After 'Handling So Many Turkeys'

Martha Stewart was confined to her bed for several days last month because of salmonella infection, the New York Post's Page Six reported.

“I never get sick, but I came down with salmonella. I think I caught it because I was handling so many turkeys around Thanksgiving," Stewart told Page Six. "I was on the 'Today' show, I did a number of other [Thanksgiving] appearances. It really hit me hard and I was in bed for days. It was terrible."

Veggie Burger Product Recalled Due to Potential for Listeria monocytogenes

Veggie Patch, a manufacturer of vegetable based food items, is recalling meatless burgers and falafel because their own internal testing program detected Listeria monocytogenes. What is the risk:
  • The meatless burgers are soy-based products (Ingredient statement below), which are considered a TCS food in the FDA Food Code. That is, the product will support the growth of organisms such as Listeria.
  • The product is considered fully cooked, so the instructions (attached below) are what would be considered heat-and-serve. These instructions would not be considered validated cooking instructions needed to destroy pathogens if present. (http://www.gmaonline.org/downloads/wygwam/121894_1.pdf is a guidance document for validating cooking instructions.)
  • This is a frozen product, so while frozen, that will prevent the growth of Listeria. Of course, if the consumer thaws the product and then holds it for days before consuming, this will allow for growth.
Question is, to what degree does the company’s food safety program, including sanitation, limit this recall to the day in question.
 
FDA News Release
VEGGIE PATCH® Voluntarily Recalls Two Items- The Ultimate Meatless Burger and Falafel

Fear the Grocery Carts?

Here is a study just released in Food Protection Trends. The study shows that grocery carts are a bit unsanitary as indicated by the presence of bacterial indicators (APC, coliforms, generic E. coli). While the study is a bit soft in the methodology (should have actually checked for pathogens, should have used better methods for testing), it does show that shopping carts are not the cleanest things in the world, and there is the possibility that carts can be a source of contamination, primarily children riding in those carts (putting their fingers on the cart seat and then sticking those same fingers in their mouth).  

But before we all go crazy worrying about grocery carts, it is important to point out this is just one of many risks that we all face each day. How about that grass where the kid is crawling….might that be a place where birds, dogs, or cats may have pooped? The refrigerator where juices from raw meats may have dripped…did it get on the apples?. That grocery store conveyor, where the packs of raw meat may have dripped…could those drops contaminated your other food packages?. How about those reusable grocery bags that never get washed after being used to carry raw meat? Where did you put your hands while eating lunch on a park bench where earlier, a group of the pigeons deposited their load as they flew by? Certainly it is important that we take precautionary measures such as washing our hands, cooking our food, and washing our grocery bags, but for each study that comes out that demonstrating the somewhat obvious, we cannot let the potential of contacting a contaminated surface become the bane of our lives. As they say, the key to a healthy immune system is a constant challenge.


Bacterial Contamination of Shopping Carts and Approaches to Control

Charles P. Gerba* and Sheri Maxwell
Dept. of Soil, Water and Environmental Science, University of Arizona, Tucson, AZ 85721, USA
Food Protection Trends, Vol. 32, No. 12, Pages 747–749

Summary

Placing children in grocery shopping carts has been implicated recently as a source of infection with Salmonella and Campylobacter in young children. This study was conducted to assess the occurrence total bacteria, coliform bacteria and Escherichia coli on grocery shopping cart handles and seats. A total of 85 shopping carts in parking lots of grocery stores were tested in five major metropolitan areas across the United States. The total numbers of heterotrophic bacteria were as great as 1.1 × 107 on the handle and seat. Coliforms were detected on 72% (62) of the carts. E. coli was identified on 18 of 35 carts (51%) on which coliform identifi­cation was conducted. The results of this study suggest the need for improved sanitation of shopping cards/baskets to reduce exposure to pathogens and potential transmission of microbial infections among shoppers.

Antibiotic-resistant pathogens in pork - reviewing the CR news release


Perhaps you have seen the latest food safety news to hit the mass media - antibiotic resistant bacterial pathogens in pork.

Is there need to worry - No.

1) Is pork that bad? No, all raw meat products - whether pork, beef, poultry, or fish - have the potential to carry bacterial pathogens such as Salmonella, or E. coli. Therefore, one just needs to properly cook (to eliminate those organisms) and properly hande (to prevent cross contamanation) raw meat products to prevent any potential for illness. Remember, use a thermometer.

2) What about the antibiotic resistance? Antibiotic resistenace adds no special ability for these organisms to resist heating and sanitizers, so these bacteria will be controlled the same as any other bacteria though proper cooking and cleaning. The biggest concern with these types of organsims are with high risk groups, so it is especially important to ensure the use of good practice when preparing food for these groups (including the elderly and young children).

 It is true that there is a link between the use of antibiotics in livestock and a higher level of antibiotic resistant organisms that can be found in that meat. And it is true that anitibiotics have been overused in livestock as well as for humans (have you been given antibiotics for a viral infection?). However, the epidemiolgical evidence is lacking in showing a tie between those organisms and increased human illness. To combat the concern, FDA recently released a guidance to promote the judicious use of medically important antibiotics in food-producing animals (
http://www.fda.gov/NewsEvents/Newsroom/PressAnnouncements/ucm299802.htm).

It is also important to note that one can find antibiotic resistant organsims in organically grown meat. So I do not agree with the assertion that is made that one should buy organically certified meat. If you feel that there are quality aspects related to organic meat, than that is one thing. But the fact that the meat is organic does not provide any real benefit regarding safety.


What’s in that pork?
 We found antibiotic-resistant bacteria and traces of a veterinary drug

Consumer Reports magazine: January 2013 
http://www.consumerreports.org/cro/pork0113.htm

 Our analysis of pork-chop and ground-pork samples from around the U.S. found that yersinia enterocolitica, a bacterium that can cause fever, diarrhea, and abdominal pain, was widespread. Some samples harbored other potentially harmful bacteria, including salmonella. And there are more reasons to be concerned about “the other white meat.”
Some of the bacteria we found in 198 samples proved to be resistant to antibiotics commonly used to treat people. The frequent use of low-dose antibiotics in pork farming may be accelerating the growth of drug-resistant “superbugs” that threaten human health.
