Report - Foodborne illness source attribution estimates for 2018 for Salmonella, Escherichia coli O157, Listeria monocytogenes, and Campylobacter

CDC issued a report "Foodborne illness source attribution estimates for 2018 for Salmonella, Escherichia coli O157, Listeria monocytogenes, and Campylobacter using multi-year outbreak surveillance data, United States" that uses outbreak data to identify the sources of foodborne illness. "

The report is from the Interagency Food Safety Analytics Collaboration (IFSAC), a tri-agency group created by the US CDC), FDA, USDA-FSIS. IFSAC developed a method to estimate the percentages of foodborne illness attributed to certain sources using outbreak data from 1998 through the most recent year for four priority pathogens: Salmonella, Escherichia coli O157, Listeria monocytogenes, and Campylobacter.

They analyzed outbreaks that were confirmed or suspected to be caused by the four priority pathogens from 1998 through 2018. (Excluded outbreaks that met one or more of the following conditions: occurred in a U.S. territory; had no identified food vehicle or contaminated ingredient; were caused by more than one pathogen (including pathogens not included in this report); were caused by both E. coli O157 and another E. coli serogroup; or were caused by both Salmonella serotype Enteritidis and another Salmonella serotype.)

Quick take-aways...

• First, nothing really new was presented in this report.
• Salmonella had the largest amount of cases and there were cases in nearly every category.  Why? Salmonella is so prevalent in the environment.
• E.coli was predominately an issue in row crops (leafy greens) and beef.  Why? Ruminants carry it and it gets onto the row crops through irrigation of those crops with contaminated water.
• Listeria cases were primarily in dairy, fruit, and raw crops.  Meat items are further down the list, much of this due to how well the meat and poultry industry has focused on controlling it.
• Campylobacter - Chicken and raw milk (although numbers from raw milk were excluded).  People focus on Salmonella in raw chicken, but Campylobacter is an equal or greater concern.  Both handled through the same ways...proper handling and cooking.

Directly from that report:
Overall Key Results

• The results are based on 905 outbreaks caused or suspected to be caused by Salmonella, 255 by E. coli O157, 44 by Listeria, and 104 by Campylobacter (after 151 outbreaks due to Dairy were excluded).
• Estimated Salmonella illnesses were more evenly distributed across food categories than illnesses from Campylobacter, E. coli O157, and Listeria; most of the illnesses for the latter pathogens were attributed to one or two food categories.
• The credibility intervals overlap for the Salmonella and Listeria categories with the highest attribution percentages, indicating no statistically significant difference among them.

Salmonella Key Results

• Over 75% of illnesses were attributed to seven food categories: Chicken, Seeded Vegetables (such as tomatoes), Pork, Fruits, Other Produce, Eggs, and Turkey.
• The credibility intervals for each of the seven food categories that account for 75.6% of all illnesses overlap with some of the others

E. coli O157 Key Results 

• Over 75% of E. coli O157 illnesses were attributed to Vegetable Row Crops (such as leafy greens) and Beef. 
• Vegetable Row Crops had a significantly higher estimated attribution percentage than all other categories. • Beef had a significantly higher estimated attribution percentage than all categories other than Vegetable Row Crops. 
• No illnesses were attributed to Eggs or Oils-Sugars.

Listeria monocytogenes Key Results 

• Over 90% of illnesses were attributed to non-meat food categories. 
• Over 75% of illnesses were attributed to Dairy and Fruits. 
• The credibility intervals for the Dairy, Fruits, and Vegetable Row Crops categories were quite wide, partly due to the small total number of outbreaks (44). The credibility intervals overlapped each other, and the intervals for the Fruits and Vegetable Row Crops categories overlapped those for some food categories with much smaller estimated attribution percentages, such as Sprouts. 
• No illnesses were attributed to Other Meat/Poultry, Game, Eggs, Other Seafood, Grains-Beans, OilsSugars, Seeded Vegetables or Other Produce.

Campylobacter Key Results 

• Over half of non-Dairy Campylobacter illnesses were attributed to Chicken (58.3%). 
• The credibility interval for Chicken did not overlap with the credibility intervals for the other categories, indicating a significantly higher estimated attribution percentage for Chicken than for any other food category. • No significant differences in the estimated attribution percentages were found among most other food categories. 
• The majority (33/56, 59%) of chicken-associated Campylobacter outbreaks were attributed to chicken liver products, which are not widely consumed in the United States. All six chicken-associated Campylobacter outbreaks caused by both C. jejuni and C. coli were attributed to chicken liver products. • No illnesses were attributable to Eggs, Grains-Beans, or Sprouts.
•  An attribution percentage for Dairy is not presented partly because most foodborne Campylobacter outbreaks were associated with unpasteurized milk, which is not widely consumed in the United States. The attribution percentages before removing Dairy were Dairy 56.5%, Chicken 25.4%, Other Seafood 4.6%, Turkey 3.6%, and Other Meat/Poultry 3.0%, and were less than 2% for each of the other categories. The Chicken attribution percentage increased to 58.3% after removing Dairy.
• Note - The attribution percentages for Dairy are not presented in the figures for Campylobacter for several reasons. Most Campylobacter Dairy outbreaks included in the database were associated with unpasteurized milk, which is not widely consumed by the general population. Moreover, an analysis of 38 case-control studies of sporadic campylobacteriosis found a much smaller percentage of illnesses attributable to consumption of raw milk than chicken.

Trader Joes Branded Frozen Edamame Imported from Asia Recalled for Potential Listeria

Trader Joe's frozen edamame (soy beans) is being recalled for potential Listeria contamination. The product was imported form southeast Asia through Tesoros Trading Company / Food Company.  The notice does not provide information on how the issue was discovered.

Not much information on Tesoros Trading Company, but likely linked to Teroros Foods.  While certain lots are listed, there would be concern for other lots or products packed in the same facility, especially if the packer did not have a robust Listeria control program.  As part of the importer's FSVP , they would have needed to identify Listeria as a hazard and then had sufficient verification support that the packer had adequate and verifiable environmental controls in place.

FDA Proposes Removing Standard of Identity for French Dressing

The US FDA announced that it was proposing to remove the Standard of Identity for French Dressing. The Standard of Identity, as we know, provides a standardized definition for a food item, in this case, French Dressing, so that when a consumer buys it from the store, they sort of know what they are buying.

"This proposed rule, if finalized, would revoke the standard of identity for French dressing. This action, in part, responds to a citizen petition submitted by the Association for Dressings and Sauces (ADS) (petition). We tentatively conclude that the standard of identity for French dressing no longer promotes honesty and fair dealing in the interest of consumers and revoking the standard could provide greater flexibility in the product’s manufacture, consistent with comparable, nonstandardized foods available in the marketplace.

"So what is French Dressing?
According to the online dictionary, French Dressing is:

n.
1. A salad dressing of oil, vinegar, and seasonings.
2. A commercially prepared creamy salad dressing that is usually pale orange to reddish-orange in color and often sweet.
From the US  Code of Federal Regulations, the Standard of Identity for French Dressing (entire listing below) states that it contains acidifying agents, vinegar and/or lemon juice, and has not less than 35 percent by weight of vegetable oil. Optional ingredients include egg and tomato juice.

The FDA proposal to remove this standard reasons:

"The petition states that there has been a proliferation of nonstandardized pourable dressings for salads with respect to flavors (Italian, Ranch, cheese, fruit, peppercorn, varied vinegars, and other flavoring concepts) and composition (including a wide range of reduced fat, “light,” and fat-free dressings) (petition at page 3). The French dressing standard of identity, according to the petition, no longer serves as a benchmark for other dressings because of the wide variation in composition to meet consumer interests (id.). Instead, the petition claims that the standard of identity has become marginalized and restricts innovation (id.). Therefore, the petition states that the French dressing standard of identity no longer promotes honesty and fair dealing in the interest of consumers (id.).

One key factor in the standard is the required level of oil.  With the demand for lower fat varieties, this standard limits that.  

When the standard of identity was established in 1950, French dressing was one of three types of dressings we identified (15 FR 5227). We generally characterized the dressings as containing a fat ingredient, an acidifying ingredient, and seasoning ingredients. The French dressing standard allowed for certain flexibility in manufacturers’ choice of oil, acidifying ingredients, and seasoning ingredients. Tomatoes or tomato-derived ingredients were among the seasoning ingredients permitted, but not required. Amendments to the standard since 1950 have permitted the use of additional ingredients, such as any safe and suitable color additives that impart the color traditionally expected (39 FR 39543 at 39554-39555).
Most, if not all, products currently sold under the name “French dressing” contain tomatoes or tomato-derived ingredients and have a characteristic red or reddish-orange color. They also tend to have a sweet taste. Consumers appear to expect these characteristics when purchasing products represented as French dressing. Thus, it appears that, since the establishment of the standard of identity, French dressing has become a narrower category of products than prescribed by the standard. These products maintain the above characteristics without a standard of identity specifically requiring them.

Additionally, French dressing products are manufactured and sold in lower-fat varieties that contain less than the minimum amount of vegetable oil (35% by weight) required by 21 CFR 169.115(a). We are unaware of any evidence that consumers are deceived or misled by the reduction in vegetable oil when these varieties are sold under names including terms such as “fat free” or “low-fat.” By contrast, these varieties appear to accommodate consumer preferences and dietary restrictions. Therefore, after considering the petition and related information, we tentatively conclude that the standard of identity for French dressing no longer promotes honesty and fair dealing in the interest of consumers consistent with section 401 of the FD&C Act. "

Should we care?  This is such a non-specific standard to begin with, brand specific variations may not make much difference to the consumer.  But FDA is "interested in any information, including data and studies, on consumer expectations regarding French dressing and whether the specifications in § 169.115 are necessary to ensure that French dressing meets these expectations."

Colorado Issues Health Alert After Uptick in Botulism Cases

Reports of botulism poisoning are very rare, much due to food safety practices that focus on preventing this deadly foodborne disease. So Colorado health officials became concerned when there was five cases of botulism poisoning since September. While there is no source for three of the cases in the report, two of the cases were related to improperly processed home-canned foods.

Baby Spinach from Canada Recalled for Potential Salmonella Contamination

A Canadian company has recalled is recalling Fresh Attitude baby spinach (5oz and 11oz)  because it has the potential to be contaminated with Salmonella.  "The recall was initiated after it was discovered that the product was possibly contaminated with Salmonella subsequent investigation indicates that the problem may have been caused by contamination of a part of a lot of Baby Spinach." [not really sure what that means...perhaps testing of a specific lot of baby spinach was positive for Salmonella?]  There have been no reported illnesses, indicating it was not an investigation but rather routine testing?

FDA Issues Warning Letter to Potato Chip Manufacturer for Allergen Mislabeling

FDA issued a Warning Letter to Frito Lay for two allergen related issues that resulted in recalls.    One occurred when at the Bakersfield, CA facility when  incorrect seasoning containing undeclared milk was applied to Lay’s Barbecue Flavored Potato Chips  and the other was a mislabeling issue at the Vancouver, WA facility when  bags of Ruffles Cheddar & Sour Cream Potato Chip potato chips were labeled “Ruffles Original Potato Chips”.  Basically, the two facilities had procedures but did not follow them.

Mislabeling at WA facility

According tot the report , the facility did not adequately implement food allergen controls at the packaging step allowing incorrect labeling where Ruffles Cheddar & Sour Cream Potato Chips were bagged as Ruffles Original bags, thus an undeclared major food allergen, milk. 

In this case, the facility did not implement their roll change procedure - they were manufacturing Ruffles Cheddar & Sour Cream Potato Chips and intended to change the bagmaker to 1.5oz size Ruffles Cheddar & Sour Cream; however, the bagmaker operator incorrectly used the Ruffles Original film. 

The allergen control procedure, “Film Splice Tracking,” is in place to indicate that at roll change the person will log the time, the identifying labeling film code, and attach the labeling film splice to the “Film Splice Verification” form, and then a second person will verify the labeling film code. 

• These splice operations were not documented on the form. 
• Also, the form indicates that the product should be identified, but on June 24, 2020, the product was not identified on this form. 
• Further, the firm discontinued attaching the labeling film splice to the form in June of 2020.

Additionally, there was a procedure to verify the correct product is in the correct package and bag coding/case coding information is accurate. "The procedure also requires that the “Product” and “Flavor” be documented and that “Product Tasted / Correct Product in Bag?” is assessed and given a “GO or NO-GO.” On June 24, 2020, during the production of the recalled bags labeled “Ruffles Original Potato Chips” but containing Ruffles Cheddar & Sour Cream Potato Chips, “Product Tasted / Correct Product in Bag?” was given a “GO” even though the product documented on the form was Ruffles Cheddar & Sour Cream, and the label was “Ruffles Original.”   Further wo employees signed the form, indicating that they verified the activities performed, and the discrepancy was not noted."

Allergen Cross Contact at the Bakersfield CA facility

The firm did not adequately implement the "Seasoning Allergens SSOP” and PSM (Product Safety Management) Procedure, which are allergen preventive control procedures to significantly minimize or prevent allergen cross-contact. "These procedures indicate that [the firm] will verify that all visible evidence of prior seasoning is removed [after] cleaning. On September 23, 2020, (b)(4) cleaning of packaging line (b)(4) in preparation for production of Lay’s Limón Flavored Potato Chips, orange residue, which was the same color as the seasoning used in milk-containing Ruffles Queso made immediately (b)(4) cleaning, was observed by our investigator. In particular, three orange residues approximately one millimeter in size were observed on the (b)(4) feeder (food contact surface), and two orange residues approximately one millimeter in size were observed on the interior surface of an unsealed finished product label for Lay’s Limón Flavored Potato Chips on the bagmaker of packaging Line (b)(4). These residues were observed after you conducted a (b)(4) clean-out and documented on your “(b)(4)” form that “the line has no visible evidence of previous products/seasoning run.” Further, a post-sanitation verification audit was conducted by your PSM auditor, and this area was determined to be ready for production and packaging of Lay’s Limón Flavored Potato Chips. Lay’s Limón Flavored Potato Chips do not contain milk."

Research - Those Darn Wooden Pallets Can Lead to Injuries

A research study out of Penn State brings to light what we have known all along - those darn wooden pallets can be an injury hazard in non-occupational settings.  "The first-ever investigation of non-occupational injuries that occur due to unintentional contact with pallets yielded startling statistics, Michael noted. From Jan. 1, 2014, to Dec. 31, 2018, there were an estimated 30,493 people who visited hospital emergency rooms for pallet-related injuries."

Certainly those professionals who work in warehouse settings know the issues, but there is an increase use of pallets in retail settings, such as in warehouse stores and retail settings where product is displayed on pallets.  Often times, these pallets are not new pallets, or grade A pallets, but those overly used pallets that are one nail from falling apart.  Then there is the consumer use of those worn-out pallets.  According to the authors...."The immense number of pallets allows for broken or beaten-up pallets to be lost from the system and grabbed by homeowners for DIY projects.....Or they break up pallets for firewood or stack firewood on them. They’re not careful and they get hurt.”
