USA – Multi-state Salmonella outbreak of unknown origin now up to 60 patients

Posted on February 5, 2021 by | Leave a comment

Food Safety News

Traceback efforts continue in a Salmonella Miami outbreak, but few details are available. Federal investigators report that the patient count has increased to 60. The source has not yet been determined.

In its original outbreak notification on Jan. 13 the Food and Drug Administration’s weekly CORE investigation table listed 48 patients. The FDA has not revealed what states are involved in the outbreak. The Centers for Disease Control and Prevention have not released information about the outbreak.

The CORE investigation table indicates that traceback is underway, but it does not provide any other information about what food or foods are part of that effort. The table refers the public to general information pages on Salmonella and the FDA investigation process.

When the outbreak was added to the weekly CORE update an FDA spokesperson told Food Safety News the agency just doesn’t have enough information on the traceback efforts yet.

Investigation – Foodborne outbreak in British Columbia related to raw milk Gouda-like products, 2018

Posted on February 1, 2021 by | Leave a comment

Gov

Abstract

Background: In 2018, a Shiga toxin-producing Escherichia coli O121 outbreak that affected seven individuals was associated with raw milk Gouda-like cheese produced in British Columbia, Canada.

Objectives: To describe the E. coli O121 outbreak investigation and recommend greater control measures for raw milk Gouda-like cheese.

Methods: Cases of E. coli O121 were identified through laboratory testing results and epidemiologic surveillance data. The cases were interviewed on exposures of interest, which were analyzed against Foodbook Report values for British Columbia. Environmental inspection of the dairy plant and the cheese products was conducted to ascertain a source of contamination. Whole genome multi-locus sequence typing (wgMLST) was performed on all positive E. coli O121 clinical and food isolates at the provincial laboratory.

Results: Four out of the seven cases consumed the same raw milk Gouda-like cheese between August and October 2018. The implicated cheese was aged longer than the required minimum of 60 days, and no production deficiencies were noted. One sample of the implicated cheese tested positive for E. coli O121. The seven clinical isolates and one cheese isolate matched by wgMLST within 6.5 alleles.

Conclusion: Raw milk Gouda and Gouda-like cheese has been implicated in three previous Shiga toxin-producing E. coli outbreaks in North America. It was recommended product labelling to increase consumer awareness and thermization of milk to decrease the risk of illness associated with raw milk Gouda and Gouda-like cheese.

Introduction

Shiga toxin-producing Escherichia coli (STEC) is a major cause of foodborne illness in North America. STEC infections cause diarrheal illness and may lead to severe complications, such as hemolytic uremic syndrome, and death. The incidence rate of O157 STEC illness has been decreasing, whereas the rate of non-O157 STEC, including O121, has been increasing in many countries, likely due to changes in laboratory methods of detection. Outbreaks of STECO121 have been associated with raw flour, fresh or frozen produce, dairy and beef products 

The risk of STEC due to unpasteurized dairy products has been previously described . Between 2002 and 2013, three E. coli O157 outbreaks associated with raw milk Gouda cheeses aged for at least 60 days were reported in North America, including one associated with a British Columbia (BC) dairy plant. Following each outbreak, public health professionals recommended strengthening control measures to decrease the risk associated with raw milk Gouda cheeses . None of these changes had been implemented in Canada by 2018.

In November 2018, another STEC outbreak associated with a raw milk Gouda-like cheese occurred in BC (population: 5.1 million).

The objective of this article is to describe the outbreak investigation and findings and reiterate the need for greater control measures related to raw milk Gouda-like cheese.

USA – Outbreak Investigation of E. coli – Leafy Greens (December 2020)

Posted on January 28, 2021 by | Leave a comment

FDA

Total Illnesses: 40
Hospitalizations: 20 (4 Cases HUS)
Deaths: 0

The FDA, along with CDC and state and local partners, investigated a multistate outbreak of E. coli O157:H7 infections in the fall of 2020. The epidemiology and traceback investigation have determined that the outbreak was linked to leafy greens. The epidemiological and traceback investigations were not able to determine a specific type of leafy green linked to illnesses. On 12/22/2020, the CDC announced that this outbreak appears to be over. This outbreak, announced by FDA and CDC on October 28, 2020, was caused by a strain of E. coli that is genetically related to a strain linked to the fall 2019 romaine outbreak.

The FDA completed a traceback investigation of multiple types of leafy greens identified in patient interviews. Although no single ranch was identified as a common source of the leafy greens, FDA and state partners also conducted on-site investigations on farms of interest.

Teams were deployed to dozens of ranches in the region to conduct large scale environmental sampling. Additionally, no Shiga toxin-producing E. coli were found on leafy greens. As part of the field investigation, teams conducted environmental sampling on and around ranches of interest to identify any factors that could have led to contamination. Samples of soil, scat or animal droppings, compost, water, and other environmental sources were collected and analyzed.

Laboratory analysis of samples is now complete. The analysis has confirmed a positive match to the outbreak strain in a sample of cattle feces, which was collected during follow-up investigations on a roadside, uphill from where leafy greens or other food identified in the traceback investigation were grown. While the finding does not provide definitive information on how E. coli may have contaminated product during the growing and harvesting season, it does confirm the presence of a strain of E. coli O157:H7 that causes recurring outbreaks in a more narrowly defined growing region and a potential, continued source of contamination.

At this time, FDA’s investigational activities have concluded. The FDA continues to review the findings from this outbreak and a detailed report will be released in the near future. This report will include recommendations shaped by the investigation findings.

In the meantime, as recommended in our Leafy Greens Action Plan, the FDA continues to recommend growers assess and mitigate risk associated with adjacent and nearby land use practices, particularly as it relates to the presence of livestock, which are a persistent reservoir of E. coli O157:H7 and other STEC.

Recommendation

CDC has declared this outbreak to be over. There is no recommendation for consumers, retailers, or suppliers.

Food Safety Website – Stop Foodborne Illness

Posted on January 27, 2021 by | Leave a comment

Stop Foodborne Illness

Incorporated as a not-for-profit in California in 1994, STOP began as a grassroots effort. The U.S. government and non-governmental organizations were not addressing this public safety issue and STOP stepped in to fill the void. The founders knew that increasing awareness about foodborne pathogens had to be a guiding principle.

Initially, STOP learned that there is not a singular government agency – there are many – that oversee food safety in the U.S. We also identified the lack of effective communication at all levels of governmental hierarchy – federal, state and local. It was clear that we weren’t the only organization seeking answers. As STOP became more knowledgeable of how food becomes contaminated, the weaknesses of the system and the complexity of the challenge of preventing foodborne illness became very apparent.

Learning that the United States government — our government — had known about emerging foodborne pathogens but lacked a comprehensive plan to combat them was disheartening. It was identified that as early as 1982, scientists and pathologists had been quietly warning the United States Department of Agriculture (USDA), Congress, and the media that a failure to inspect meat and poultry for bacteria would lead to a food safety disaster.

Time was of the essence and although there was significant resistance at every turn, STOP knew it held the truth.

STOP added its strong voice to the Safe Food Coalition, a group of consumer, public health and labor organizations which has advocated for improvements to the food safety system, particularly with respect to meat and poultry, since 1986. Industry held power, influence, and money. Victims’ families and survivors held onto lives that had been irreparably altered by foodborne illness. Families continued to tell their stories through the advocacy of STOP and its coalition partners.

STOP’s voices became a clarion call for change and eventually STOP was invited to participate in policy making. After countless hours spent educating the USDA and the meat industry about the devastation caused by E. coli, STOP became a key element in facilitating the first meat and poultry reforms since 1906. In 1996, STOP founders Roni and Nancy, were invited to witness this historic overhaul being signed into law by President Clinton.

Research – Monitoring online posts by consumers could help improve food safety

Posted on January 27, 2021 by | Leave a comment

Phys Org

An estimated 48 million cases of foodborne illness are contracted in the United States every year, causing about 128,000 hospitalizations and 3,000 deaths, according to the Centers for Disease Control (CDC). In some instances, the source is well known, such as a batch of tainted ground beef that infected 209 people with E. Coli in 2019. But 80 percent of food poisoning cases are of unknown origin, making it impossible to inform consumers of hazardous food items.

David Goldberg, assistant professor of management information systems at San Diego State University, wants to improve the traceability and communication of risky  products. In a new study published by the journal Risk Analysis, his research team proposes a new Food Safety Monitoring System (FSMS) that utilizes consumer comments posted on websites to identify products associated with food-related illnesses.

The researchers utilized an AI technology called text mining to analyze comments and reviews from two websites: Amazon.com, the world’s largest e-commerce retailer, and IWasPoisoned.com, a site where consumers alert others to cases of food poisoning. The database consisted of 11,190 randomly selected Amazon reviews of “grocery and canned food” items purchased between 2000 and 2018, along with 8,596 reviews of food products posted on IWasPoisoned.com. These two datasets allowed the researchers to test the text mining tools before analyzing 4.4 million more Amazon reviews.

UK – An outbreak of human listeriosis associated with frozen sweet corn consumption: Investigations in the UK

Posted on January 27, 2021 by | Leave a comment

Science Direct

The use of Whole genome sequencing (WGS) identified a multi-country outbreak of human listeriosis associated with consumption of frozen sweet corn produced in Hungary. The purpose of this report was to summarise information on the cases occurring in the UK which were part of this outbreak and outline investigations on the presence of Listeria monocytogenes in the affected food chain.

Prior to the international recall of this product in 2018, 12 UK cases of listeriosis were identified as infected by the outbreak strain between 2015 and 18. Epidemiological and microbiological investigations confirmed these cases as belonging to the outbreak. A further case occurred in 2019 and a contaminated frozen pack from one of the implicated batches of sweet corn was recovered from the patient’s domestic freezer.

The outbreak strain was also detected in products from a sandwich manufacturer in 2018 which added frozen sweet corn directly to sandwich fillings. The sandwich manufacturer’s sweet corn was supplied by a distributor in England which obtained frozen products from the Hungarian manufacturer implicated in the outbreak. Within the distributor’s premises, 208 food and environmental samples were taken: L. monocytogenes was detected in 44% of 70 samples of frozen sweet corn and 5% of 79 other foods.

The outbreak strain was detected in the frozen sweet corn, in one other frozen food (mixed vegetables) and in the factory environment. The outbreak strain was also recovered from frozen beans on retail sale in the first four months of 2019. Five other L. monocytogenes strains together with two other Listeria species were detected in samples from the importer’s premises. One of the L. monocytogenes strains in the importer’s factory, which was distinct from the outbreak strain, was also recovered from sweet corn collected from the sandwich manufacturer, sweet corn tested in England in 2013 and 2016 and the blood of two cases of human listeriosis which occurred in England in 2014. This report shows how analysis by WGS provides evidence to understand complex food chains.

This report also highlights risks for transmission of human listeriosis from frozen sweet corn and the potential for misuse of this food as a ready-to-eat product.
