Research – Survival of Salmonella enterica in Military Low Moisture Food Products during Long Term Storage at 4°C, 25°C and 40°C

Journal of Food Protection

Salmonella enterica  has been increasingly implicated in foodborne outbreaks involving low moisture foods (LMF) during the recent decade. This study aimed to investigate the potential for persistence of  Salmonella enterica  in a range of low moisture foods (LMF) during storage at 3 temperatures. LMF products, boil-in-bag eggs (freeze dried product), chocolate protein drink, cran-raspberry first strike bars, mocha dessert bar, and peanut butter, were inoculated with a five strain cocktail of S. enterica and stored at 4°C, 25°C, or 40°C for 36 mos. Salmonella populations remained above 7 log CFU/g in all products stored at 4°C and above 6 log CFU/g in products stored at 25°C excluding the cran-raspberry bars. Storage at 40°C resulted in Salmonella populations above 5.5 log CFU/g in boil-in-bag eggs after 36 mos and demonstrated survivability for 12 mos or less in the other five products.  Additionally, a mocha bar production temperature profile study identified rapid cooling of bars in which the temperatures reached would have no measurable impact on  Salmonella  populations. The results indicate the ability of  Salmonella  to survive in a variety of LMF category foods even under adverse storage conditions and identifies how the food matrix may affect  Salmonella  survivability. The data indicate the importance of establishing food processing procedures that adequately mitigate the presence of Salmonella throughout food processing systems while also increasing comprehensive understanding of Salmonella survivability mechanisms.

Bali – 21 students in Lombok got food poisoning after eating deep fried tempe

Coconuts Bali

Dozens of students from a madrasah (Islamic school) in Central Lombok are suspected to have gotten food poisoning after snacking on deep fried tempe, for which they had to be taken to the local community clinic (Puskesmas).

West Praya sub-precinct chief, Heri Indrayanto, said in a statement that the students bought the deep fried tempe from a street vendor identified as M and ate them with chili sauce during recess.

“It is suspected that the victims got food poisoning after eating the fried tempe with chili sauce,” Heri said.

Fifteen minutes after consuming the fritter, the students started to get headaches and felt nauseous, while some started vomiting. They were then taken to the nearest Puskesmas for treatment.

Heri said a total of 21 students had food poisoning, and even the seller M also experienced the same symptoms. Authorities had seized all the ingredients and sent them for a lab test at the Health Agency in Central Lombok.

USA – Outbreak Investigation of Salmonella Oranienburg: Whole, Fresh Onions (September 2021)

FDA

FDA and CDC are investigating illnesses linked to whole, fresh onions. Do not eat, sell, or serve certain onions from ProSource Inc.

The FDA, along with CDC and state and local partners, is investigating a multistate outbreak of Salmonella Oranienburg infections linked to whole, fresh onions. FDA’s traceback investigation is ongoing but has identified ProSource Inc. (also known as ProSource Produce, LLC) of Hailey, Idaho as a source of potentially contaminated whole, fresh onions imported from the State of Chihuahua, Mexico.

ProSource Inc. has agreed to voluntarily recall red, yellow, and white onions imported from the State of Chihuahua, Mexico, with import dates from July 1, 2021 through August 27, 2021. Descriptors of these onion types include, but are not limited to, jumbo, colossal, medium, and sweet onions.

Illness subclusters investigated in this outbreak are currently associated with restaurants and food service locations. The investigation is ongoing to determine the source of contamination and if additional products or firms are linked to illness. The FDA is working to determine if these onions were available to consumers through grocery stores. Additional information will be provided as it becomes available.

Recommendation

Advice for restaurants, retailers and consumers: Restaurants, retailers and consumers should not eat, sell, or serve red, yellow, and white onions supplied by ProSource Inc. that were imported from the State of Chihuahua, Mexico from July 1, 2021 through August 27, 2021, or products containing such onions. Consumers should ask if the onions being served or sold were supplied by ProSource Inc. and imported from the State of Chihuahua, Mexico. If you still cannot determine if your onions were supplied by ProSource Inc and imported from the State of Chihuahua, Mexico, do not sell, serve, or eat them, and throw them out.

Potentially affected red, yellow, and white onions from ProSource Inc. were imported between July 1, 2021 through August 27, 2021. Onions can last up to three months if stored in a cool, dry place. Restaurants, retailers, and consumers who suspect having purchased such onions may still have them in storage and should not eat, sell, or serve them, and should throw them out.

FDA recommends that anyone who received or suspects having received such onions imported by ProSource Inc. between July 1, 2021 through August 27, 2021 to use extra vigilance in cleaning and sanitizing any surfaces and containers that may have come in contact with these products to reduce the risk of cross-contamination. This includes cleaning and sanitizing cutting boards, slicers, countertops, refrigerators, and storage bins.

Consumers who have symptoms of Salmonella infection should contact their health care provider. Most people with salmonellosis develop diarrhea, fever, and abdominal cramps. More severe cases of salmonellosis may include a high fever, aches, headaches, lethargy, a rash, blood in the urine or stool, and in some cases may become fatal.

Suppliers and Distributors: Suppliers, distributors, and others in the supply chain should not use, ship, or sell red, yellow, and white onions from ProSource Inc. that were imported from the State of Chihuahua, Mexico or food products containing such onions. Suppliers and distributors that re-package raw onions should use extra vigilance in cleaning any surfaces and storage areas that may have come into contact with such onions from ProSource Inc. If there has been potential cross contamination or mixing of onions from other sources with such onions from ProSource Inc., suppliers and distributors should discard all comingled and potentially cross-contaminated product.

Investigation Background

October 20, 2021

The FDA, along with CDC and state and local partners, is investigating a multistate outbreak of Salmonella Oranienburg infections linked to whole, fresh onions. FDA’s traceback investigation is ongoing but has identified ProSource Inc. (also known as ProSource Produce, LLC) of Hailey, Idaho as a source of potentially contaminated whole, fresh onions imported from the State of Chihuahua, Mexico.

Epidemiological data collected by investigators from the CDC and state and local partners identified 20 illness clusters at restaurants where onions were served. Information from these clusters shows that many ill people ate raw onions. Investigators worked to identify a common food item eaten by all of the sick people in an effort to identify the source of the outbreak.

State officials collected food items from some of the restaurants where sick people ate. The outbreak strain of Salmonella Oranienburg was found in a sample taken from a takeout condiment cup containing cilantro and lime. The sick person reported that the condiment container also contained onions, but none were left in the cup when it was tested. Because multiple food items were present in the container and in the sample that was tested, it is not possible to know which food item was contaminated.

FDA’s traceback investigation identified ProSource Inc. as a common supplier for many of the restaurants that sick people reported eating at, including the restaurant where the sample from the condiment cup containing cilantro, lime, and previously onions, was collected.

The FDA continues to conduct its traceback investigation to determine if additional products or suppliers have been affected. Additional information will be provided as it becomes available.

Recall Information

ProSource Inc. has agreed to voluntarily recall red, yellow, and white onions imported from the State of Chihuahua, MX, with import dates from July 1, 2021 through August 27, 2021. Descriptions of these onion types include, but are not limited to, jumbo, colossal, medium, and sweet onions. Additional recall information will be made public as soon as it is available from ProSource Inc.

USA – Kentucky reports outbreak of E. coli due to food distribution

Food Poison Journal

Kentucky Cabinet for Health and Family Services reports that ten Kentuckians recently tested positive with a strain of E. coli O157:H7. Of the cases, two individuals developed a rare but serious condition called hemolytic uremic syndrome (HUS). Public health investigators have not yet identified the source of the outbreak but have noted that some sort of food distribution is likely.

The reported cases primarily include adults, many of whom reside in western Kentucky. No deaths linked to the outbreak have been reported but six people have been hospitalized. Health care providers have been notified of the outbreak and are advised to be alert for patients experiencing acute diarrheal illness, which could be associated with E. coli. This is a particular strain of E. coli that produces a type of toxin (Shiga toxin) that can be dangerous for those infected.

USA – U.S. and Canada part of Salmonella outbreak linked to tahini and halva

Food Safety News

The United States and Canada are part of an outbreak affecting Europe because of Salmonella in tahini and halva from Syria.

The United States has reported six Salmonella Mbandaka cases, one in 2020 and the rest this year.

Interviews were conducted with two people: both report shopping at international markets that stock mostly Arabic and Middle Eastern foods and ingredients, and ate items containing tahini. Interviews are pending on the remaining ill people. Two have traveled to Syria and have not been reachable by public health officials.

Ill people range from less than one to 57 years old, with a median age of 19.5 years. Illness onset dates are from Nov. 19, 2020 to Sept. 5, 2021.

Canada has eight confirmed cases: five of Salmonella Mbandaka, two of Salmonella Havana and one of Salmonella Orion from 2019 to 2021.

USA – Patient dies in hepatitis A outbreak traced to restaurants in Virginia

Food Safety News

One person has died in a hepatitis A outbreak associated with three restaurants in the Roanoke, VA, area, according to state officials, and two more people have been added to the patient list.

“We don’t believe there is an ongoing threat to the public,” said Christ Wills of the Roanoke City and Alleghany Health Districts, which is a subagency of the Virginia health department.

However, Wills told Food Safety News today there will likely be more sick people than the 37 who have been identified because of the long incubation time for the virus. As of today, 26 of the patients have been so sick they had to be admitted to hospitals. The age range of patients is now trending to include younger patients with people from 31 to 79 years old now infected.
