USA – Baked Goods linked to Salmonella Outbreak in Ohio

Food Poison Journal

Allen County Public Health (ACPH) is investigating a potential Salmonella outbreak affecting Allen, Putnam and Hancock counties. ACPH was notified by Hancock County regarding a multi-county Salmonella outbreak with illness onsets currently ranging from Oct. 1-6, 2022. As of Monday, Allen County had one confirmed case. Chances of other counties being affected is possible.

Undercooked food is the source for most illnesses related to Salmonella. This particular outbreak may be linked to baked goods prepared at a home bakery and distributed at establishments in Allen, Hancock and Putnam Counties. Diagnosing Salmonella infection requires testing a specimen (sample), such as stool (poop) or blood. Infection is diagnosed when a laboratory test detects Salmonella bacteria in stool, body tissue, or fluids.

USA – Updated – Outbreak Investigation of E. coli O121:H19 Frozen Falafel (October 2022)

FDA

The FDA, along with CDC and state and local partners, are investigating a multistate outbreak of E. coli O121:H19 infections linked to Earth Grown frozen falafel.

Based on epidemiologic information provided by CDC and interviews conducted by state and local public health officials, of 18 people interviewed, 15 reported shopping at ALDI stores. Among these 15 people who reported shopping at ALDI stores, 6 reported eating Earth Grown brand frozen falafel purchased from ALDI in the week before getting sick.

On October 6, 2022, the manufacturer of Earth Grown frozen falafel, Cuisine Innovations, initiated a voluntary recall. Recalled products include Earth Grown vegan traditional falafel and garlic & herb falafel distributed and sold exclusively by ALDI. Additional information on recalled products is available in the firm’s recall notice.

On October 6, 2022, ALDI removed any remaining Earth Grown frozen falafel from stores.

FDA’s investigation is ongoing. Updates to this advisory will be provided as they become available.

Recommendation

Consumers, restaurants, and retailers should not eat, sell, or serve recalled Earth Grown Traditional Falafel or Garlic & Herb Falafel sold exclusively by ALDI after June 24, 2021.

These items are no longer available for sale but were sold frozen and have a long shelf-life of 18 months, so consumers should check their freezers for these products. If you have recalled frozen falafel in your freezer, do not eat or serve them.

Research – Efficacy of Repeated Applications of Bacteriophages on Salmonella enterica-Infected Alfalfa Sprouts during Germination

MDPI

Nontyphoidal Salmonella enterica is one of the leading pathogens for foodborne outbreaks in a multitude of food commodities, including alfalfa sprouts, which are commonly consumed raw. The food industry has commonly used chlorinated washes, but such methods may not be perceived as natural; this can be a detriment as a large portion of sprouts are designated for the organic market. A natural and affordable antimicrobial method that has been acquiring popularity is the use of bacteriophages. This study compared the efficacy of repeated daily applications and a single application of two separate bacteriophage cocktails (SE14, SE20, SF6 and SE14, SF5, SF6) against four Salmonella enterica (S. enterica) strains on germinating alfalfa sprout seeds from days 0 to 7. The results show S. Enteritidis to be the most susceptible to both cocktails with ~2.5 log CFU/mL decrease on day 0 with cocktail SE14, SF5, and SF6. S. enterica populations on all strains continued to grow even with repeated daily bacteriophage applications but in a significantly decreased rate (p < 0.05) compared with a single bacteriophage application. The extent of the reduction was dependent on the S. enterica strain, but the results do show benefits to using repeated bacteriophage applications during sprout germination to reduce S. enterica populations compared with a single bacteriophage application.

USA – Outbreak Investigation of Listeria monocytogenes: Brie and Camembert Soft Cheese Products (September 2022)

FDA

The FDA, along with CDC and state and local partners, is investigating a multistate outbreak of Listeria monocytogenes infections linked to Brie and Camembert soft cheese products, including all baked Brie cheeses, manufactured by Old Europe Cheese, Inc. of Benton Harbor, MI, and sold at various retailers under multiple labels and brands.

On September 30, 2022, Old Europe Cheese, Inc. voluntarily recalled multiple brands of Brie and Camembert cheeses produced at their Michigan facility and on October 5, 2022 expanded their recall to include multiple brands of baked Brie products. The firm has also halted production and distribution of their Brie and Camembert products from the Michigan facility and is working with FDA on corrective actions. Consumers, restaurants, and retailers should not eat, sell, or serve recalled products and should throw them away; this includes Best By Dates ranging from September 28, 2022 to December 14, 2022, and all flavors and quantities.

An expanded list of recalled products and stores that potentially sold these products is available below and on the firm’s recall. Swiss American has also issued a voluntary recall of their St. Louis Brie products sourced from Old Europe Cheese Inc.’s Michigan facility. A full list of their products can be found on the firm’s recall notice.

FDA’s investigation is ongoing to determine if additional products are potentially contaminated. Updates to this advisory will be provided as they become available.

Recommendation

Consumers, restaurants, and retailers should not eat, sell, or serve recalled products and should throw them away; this includes Best By Dates ranging from September 28, 2022 to December 14, 2022, and all flavors and quantities. An expanded list of recalled products and stores that potentially sold these products is available below and on the firm’s recall.

Retailers may have repackaged bulk Old Europe Cheese items into smaller containers and sold this repackaged product to consumers. This repackaged product may not bear the original labeling and product information. If you are unsure where your Brie or Camembert cheese products are from, ask your retailer or throw them away.

Listeria is most likely to sicken pregnant people and their newborns, adults aged 65 or older, and people with weakened immune systems. Other people can be infected with Listeria, but they rarely become seriously ill.

Call your healthcare provider right away if you have these symptoms after eating Old Europe Cheese Inc. Brie and Camembert products:

  • Pregnant people typically experience only fever, fatigue, and muscle aches. However, Listeria infection during pregnancy can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.
  • People who are not pregnant may experience headache, stiff neck, confusion, loss of balance, and convulsions, in addition to fever and muscle aches.

Follow FDA’s safe handling and cleaning advice and 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, including retailers who repackaged bulk recalled cheese. Listeria can survive in refrigerated temperatures and can easily spread to other foods and surfaces.

New Zealand – links Hepatitis A berry cases to EU illnesses

Food Safety News

Officials in New Zealand investigating Hepatitis A cases linked to berries have identified a connection with a past outbreak in Europe.

There are 12 hepatitis A infections from eating frozen berries in New Zealand. Eight have been linked by genetic sequencing, meaning they were likely exposed to the same source of the virus. Seven people have been hospitalized. The virus attacks the liver. The Ministry for Primary Industries (MPI) was informed by the Ministry of Health of three Hepatitis A cases in September.

Foodstuffs Own Brands has recalled various Pams brand frozen berry products because of a possible link to the hepatitis A cases. Products are being removed from New World, Pak’n Save and Four Square shops nationwide, and from Trents and Raeward Fresh stores in the South Island.

USA – Torero’s Mexican Restaurant in Renton linked to E. coli Outbreak

Food Poison Journal

Summary

Public Health is investigating an outbreak of Shiga toxin-producing E. coli (also known as STEC) associated with diarrhea and abdominal pain at Torero’s Mexican Restaurant in Renton.

The investigation is ongoing. At this time, we have not identified how STEC was spread within the restaurant. This is not uncommon for STEC outbreaks, because the bacteria can spread through contaminated food items, environmental surfaces, and from person to person.

Illnesses

Since September 5, 2022, 3 people from 3 separate meal parties reported becoming ill after eating food from Torero’s Mexican Restaurant in Renton on September 3, 2022 and September 7, 2022. All of the people developed one or more symptoms consistent with STEC, including diarrhea (often bloody), abdominal cramping, nausea, and vomiting. We have not identified any ill employees.

USA – CDC says outbreak linked to Wendy’s sandwiches is over with more than 100 sick

Food Safety News

Federal officials have declared that an outbreak of E. coli O157:H7 infections related to romaine lettuce on Wendy’s sandwiches has ended.

The Centers for Disease Control and Prevention is reporting that the total number of confirmed patients is 109, up from the 97 reported in its most recent update on Sept. 1. About half — 52 — of the patients have been so sick they had to be admitted to hospitals. Thirteen of the patients developed hemolytic uremic syndrome (HUS), a serious often life-threatening condition that can cause kidney failure. No one had died as of this evening.

As of the report tonight from the CDC the specific source of the E. coli could not be 100 percent confirmed. However, 83 percent of 82 patients for whom the information was available reported eating at Wendy’s before becoming ill.

“The true number of sick people in this outbreak is likely much higher than the number reported, and the outbreak may not have been limited to the states with known illnesses. This is because many people recover without medical care and are not tested for E. coli,” according to the CDC statement.

USA – More than 200 backpackers and rafters sickened in Grand Canyon National Park backcountry- Suspected Norovirus

Food Safety News

Between April 1 and June 17, 2022, at least 222 rafters and backpackers became infected with acute gastroenteritis, most likely norovirus, according to the Centers for Disease Control and Prevention (CDC). This is the largest outbreak of acute gastroenteritis documented in the Grand Canyon National Park backcountry.

Preliminary analysis of illness characteristics and portable toilet specimen test results suggested norovirus as the primary causative agent of illness. Norovirus spreads quickly through person-to-person contact and contaminated food or beverages and can persist in the environment. The bacteria can live for days to weeks on hard surfaces.

River outfitters and National Park staff members partnered to enable the implementation of prevention and control measures.

Norovirus-associated acute gastroenteritis is highly transmissible in settings with close person-to-person contact and decreased access to hand hygiene. Because many trips use the same campsites and place-portable toilets in the same locations, particles could have been transmitted to surfaces, beach sand or river water where new groups could have encountered them, and then transmitted the virus both from person-to-person and trip-to-trip.
