USA – FDA Core Outbreak Table – Investigations of Foodborne Illness Outbreaks

FDA

What’s New

  • For the outbreak of Listeria monocytogenes (ref #1205) in a not yet identified food, FDA has initiated traceback, an on-site inspection, and sample collection and analysis.
  • For the outbreak of Salmonella Newport (ref# 1201) in a not yet identified food, the case count has increased from 43 to 44 cases.
  • For the outbreak of Salmonella Sundsvall and Oranienburg (ref #1203) linked to cantaloupe, the recall was expanded to include additional retailers and wholesalers who received the recalled melons. See the Outbreak Advisory for additional information.

USA – Outbreak Investigation of Salmonella: Onions (October 2023) – CDC Outbreak is Over

FDA

Sample Product Image from the Outbreak Investigation of Salmonella Related to Onions (October 2023)

Product

Recalled Gills Onions-brand diced yellow onions, diced onions & celery, diced mirepoix, and diced red onions with use-by dates in August 2023.

The US Food and Drug Administration’s (FDA) investigation is complete; the Centers for Disease Control and Prevention (CDC) declares the outbreak over.

Stores Affected

  • Recalled Gills Onions were sold to foodservice and institutions nationwide and in Canada. The firm has directly notified foodservice customers who received recalled product.
  • Recalled product was sold to retailers in Arizona, California, Idaho, Montana, Oregon, and Washington.

The FDA and CDC, in collaboration with state and local partners, investigated an outbreak of Salmonella infections linked to recalled diced onions under the Gills Onions brand name.

As part of this investigation, FDA collected multiple water, environmental, and product samples from the farm that supplied the contaminated onions to Gills Onions. Six of the samples, three water and three environmental, were positive for Salmonella spp. Whole Genome Sequencing (WGS) analysis confirmed that the strain of Salmonella found in isolates associated with three of the samples matched the same strain of Salmonella causing illnesses in this outbreak. Additional Salmonella isolates from the samples were detected, and CDC identified people who got sick with these strains of Salmonella. FDA and CDC partners reviewed the available data; however, there was not enough epidemiologic or traceback evidence to implicate a product or source of contamination for those illnesses.

As of December 4, 2023, CDC announced that the outbreak is over. CDC reports a total of 80 illnesses in 23 states. There has been a total of 18 hospitalizations and one death associated with this incident. The last illness onset was November 11, 2023. FDA’s investigation is complete.

USA- 140 Illnesses Linked To Sushi Nine Restaurant In Raleigh

Food Poisoning News

On the seventh of December, 2023, WRAL News announced an outbreak of 140 illnesses connected to the sushi restaurant, Sushi Nine. The Raleigh, North Carolina-based restaurant received notifications from consumers with adverse reactions after having consumed sushi at its business.

While a virus is believed to be the cause, the blame is under investigation. According to local reports, patrons reported experiencing symptoms that correlate similarly with those of Norovirus, often referred to as the “winter vomiting disease.” One victim, Austin Freels, shared details of his illness following eating sushi at Sushi Nine, while with family and friends a few days prior to his wedding. Austin experienced “agonizing” stomach pain, and mentioned to WRAL that while at the Emergency Room, he was told by health professionals his food poisoning case was “…one of the most severe cases…they had seen…”

Research – Multi-country outbreak of Listeria monocytogenes linked to fish products

EFSA

Between 2022 and 2023, the outbreak has affected Austria, Belgium, Italy, Germany, and the Netherlands, with reports of 17 cases and two deaths. Infections have occurred mainly in the elderly. Historical human cases related to the outbreak have been detected since 2011.

Advanced molecular typing techniques identified a variant of Listeria monocytogenes which was detected in the majority of the 2022-2023 cases. The analysis of the data suggests a connection to two establishments in Lithuania during the same period. These establishments were found to have introduced contaminated fish products into the retail markets of Germany and Italy. Production has been stopped in a Lithuanian plant, likely reducing the risk of infections. Data regarding the distribution of contaminated products in Austria, Belgium, and the Netherlands is currently not available.

EFSA and ECDC experts say that further investigations are needed to identify the origin of the contamination. This will allow national authorities to implement targeted control measures and mitigation actions. Experts also recommend following good manufacturing practices, hygiene rules, and effective temperature control throughout the entire food production, distribution, and storage chain, including in households. Consumers are advised to maintain low refrigerator temperatures to inhibit the potential proliferation of bacteria such as Listeria which could be present in ready-to-eat foods.

Swedish E. coli cases linked to imported parsley

Food Safety News

Contaminated parsley imported from southern Europe has been linked to at least 150 E. coli cases in Sweden.

Over 100 people were infected by Enterotoxigenic E.coli (ETEC) and Enteropathogenic E. coli (EPEC) after eating food during a conference in Jönköping at the end of October. A similar outbreak sickened 50 people in Stockholm.

In Stockholm, people were infected around the same time at a restaurant that served parsley from the same producer. This led health officials to believe it was likely parsley from Italy that caused the outbreaks.

A total of 104 participants at the conference reported they had suffered illness. Samples were taken from four cases. Analysis showed they were infected with different combinations of pathogenic E. coli such as ETEC, EPEC, and Enteroaggregative E. coli (EAEC).

Research -High technology is the key to detecting foodborne outbreaks over space and time

Lex Blog

Most people think of foodborne illness outbreaks as spanning a few days or weeks. But, with current technology, disease detectives can find patients of a single outbreak spread across several years and multiple states.

That is the case with an ongoing outbreak of Listeria illnesses linked to fresh peaches that began in 2018. So far, 11 patients have been identified, most recently found in August this year. One of the patients died. Recent recalls of peaches, nectarines, and plums have been initiated while public health officials continue investigating the outbreak.

The links between people sickened in the outbreak this year and the initial patient in 2018 were made possible using whole genome sequencing (WGS). Whole genome sequencing has been likened to fingerprinting used in criminal investigations, but WGS allows the Centers for Disease Control and Prevention to look at millions of pieces of data.

“WGS examines more than 4.5 million ‘letters’ of the genetic code in disease-causing bacteria such as Salmonella. Bacteria closely related by WGS are more likely to have originated from the same source than more distantly related bacteria,” said John Besser, who retired in 2019 as Deputy Chief of the Enteric Diseases Laboratory Branch at the CDC. He continues to work on CDC-related projects through the Association of Public Health Laboratories.

“Ill persons in a WGS cluster will likely have shared exposure, such as a contaminated food product. By focusing on WGS clusters, investigators can detect outbreaks when they are small, even if cases are dispersed over multiple states or widely separated in time.”

USA -More than two dozen report illnesses after eating at a North Carolina restaurant

Food Safety News

Eurofins

County officials in North Carolina are investigating an outbreak of foodborne illnesses linked to a sushi restaurant.

Patrons of Sushi Nine on Western Boulevard in Wake County reported illnesses with symptoms common to norovirus virus infection. The first case was reported on Nov. 30 and subsequent patients continue to be identified. As of Dec. 7 there are 31 people who have reported symptoms.

Local media are reporting that county investigators say it’s too early to tell what caused the virus. They are looking at food storage and preparation as well as norovirus.
