USA – Georgetown University reports outbreak among students; source unknown

Food Safety News

At least a dozen students at Georgetown University have reported being sick with symptoms that resemble foodborne illness and an official says they may be part of a nationwide outbreak of Salmonella infections.

Chief Public Health Officer Dr. Ranit Mishori says the school is working to determine the cause of the illnesses.

“At this time we do not know the cause of the symptoms, but it is prudent to assume they are related to an infectious process. Please be aware that the U.S. Centers for Disease Control and Prevention has reported a national outbreak of Salmonella from an unknown source,” according to a letter Mishori sent to students and staff. 

Students have reported symptoms including severe stomach pains, vomiting and diarrhea, which are consistent with foodborne illness.

USA – Outbreak Investigation of Salmonella Weltevreden: Frozen Pre-cooked Shrimp (April 2021)

FDA

The FDA, along with CDC and state and local partners, investigated a multistate outbreak of Salmonella Weltevreden infections linked to the consumption of frozen cooked shrimp manufactured by Avanti Frozen Foods of India.

As of September 21, 2021, CDC announced that the outbreak is over. There are a total of nine illnesses in four states. The last illness onset date was July 17, 2021.

Based on FDA’s completed traceback investigation and sample results, the frozen cooked shrimp manufactured by Avanti Frozen Foods of India were linked to this outbreak. The FDA worked with Avanti Frozen Foods of India to ensure that potentially contaminated frozen cooked shrimp were removed from the market.

On August 13, 2021, Avanti Frozen Foods of India expanded its recall of frozen cooked shrimp to include frozen cooked shrimp products imported into the U.S. from November 2020 to May 2021. Since Avanti Frozen Foods expanded its recall, downstream recalls have been initiated for sushi products containing recalled shrimp, sold in the state of California:

Research – Novel Outbreak-Associated Food Vehicles, United States

CDC

Novel outbreak-associated food vehicles (i.e., foods not implicated in past outbreaks) can emerge as a result of evolving pathogens and changing consumption trends. To identify these foods, we examined data from the Centers for Disease Control and Prevention Foodborne Disease Outbreak Surveillance System and found 14,216 reported outbreaks with information on implicated foods. We compared foods implicated in outbreaks during 2007–2016 with those implicated in outbreaks during 1973–2006. We identified 28 novel food vehicles, of which the most common types were fish, nuts, fruits, and vegetables; one third were imported. Compared with other outbreaks, those associated with novel food vehicles were more likely to involve illnesses in multiple states and food recalls and were larger in terms of cases, hospitalizations, and deaths. Two thirds of novel foods did not require cooking after purchase. Prevention efforts targeting novel foods cannot rely solely on consumer education but require industry preventive measures.

Foodborne illness is a major public health issue in the United States; millions of persons become ill from contaminated food every year (1). Most cases are sporadic (i.e., not associated with a disease outbreak) (2), and the responsible food(s) is often undetermined. Outbreaks provide an opportunity for public health agencies to determine shared exposures and the source of infection. Many food safety laws and regulations, industry practices, and consumer education efforts have been implemented to make foods safer. Nevertheless, evolving foodborne pathogens and changing consumption trends provide continued opportunities for contamination and illness (37). Within these changing conditions, novel outbreak-associated food vehicles (i.e., foods not implicated in prior outbreaks) can emerge. Identifying these novel food vehicles provides an opportunity to determine emerging sources of illness and to inform prevention policies. To identify novel food vehicles reported during 2007–2016, we examined data from the Centers for Disease Control and Prevention (CDC) Foodborne Disease Outbreak Surveillance System (FDOSS).

USA – Restaurants Are Included in a Salmonella Outbreak That Has Sickened 127

Food Poisoning Bulletin

Restaurants are included in a Salmonella outbreak that has sickened at least 127 people in 25 states, according to the Centers for Disease Control and Prevention (CDC). The government does not yet know which food item caused this outbreak, or if there is another cause.

Eighteen people, out of 49 that gave information to health officials, have been hospitalized, which is a rate of 37%, almost double the typical Salmonella outbreak rate. This could mean that more vulnerable people were sickened, or that the pathogen is quite virulent, or that the pathogen load in the food was quite high.

The CDC has stated that several subclusters at restaurants in multiple states have been identified. These subclusters can help officials solve outbreaks, since they can use traceback from restaurant supplier purchases to try to identify a common food.

Salmonella outbreak at La Mex restaurant in Morris, Illinois may be part of a multistate outbreak, according to the Grundy County Health Department. But there is no official word on whether that outbreak is part of this larger one.

Korea – Food Poisoning Victims Sue ‘Gimbap’ Franchise – Salmonella

Korea BizWire

Over 130 people have lodged a damages suit against a restaurant franchise that sells “gimbap,” or seaweed rice rolls with vegetables, over food poisoning.

Park Young-saeng, an attorney at Jungjin law firm, said Tuesday that he filed a damages suit the previous day with the Suwon District Court in Seongnam, a Gyeonggi Province city just south of Seoul, on behalf of 135 victims of food poisoning incidents at two stores of a gimbap chain in the city.

The victims have requested a total of about 400 million won (US$342,960) in compensation, or 3 million won per person, from the franchise and the two restaurants.

A total of 276 people who ate gimbap at the two branches of a gimbap chain in Seongnam between July 29 and Aug. 2 showed food poisoning symptoms. Forty of them were hospitalized for treatment.

According to health authorities, salmonella bacteria were found in clinical specimens from the patients and cooking tools used at the restaurants.

Research – Epidemiological investigations identified an outbreak of Shiga toxin-producing Escherichia coli serotype O26:H11 associated with pre-packed sandwiches

Cambridge Org

In October 2019, public health surveillance systems in Scotland identified an increase in the number of reported infections of Shiga toxin-producing Escherichia coli (STEC) O26:H11 involving bloody diarrhoea. Ultimately, across the United Kingdom (UK) 32 cases of STEC O26:H11 stx1a were identified, with the median age of 27 years and 64% were male; six cases were hospitalised. Among food exposures there was an association with consuming pre-packed sandwiches purchased at outlets belonging to a national food chain franchise (food outlet A) [odds ratio (OR) = 183.89, P < 0.001]. The common ingredient identified as a component of the majority of the sandwiches sold at food outlet A was a mixed salad of Apollo and Iceberg lettuce and spinach leaves. Microbiological testing of food and environmental samples were negative for STEC O26:H11, although STEC O36:H19 was isolated from a mixed salad sample taken from premises owned by food outlet A. Contamination of fresh produce is often due to a transient event and detection of the aetiological agent in food that has a short-shelf life is challenging. Robust, statistically significant epidemiological analysis should be sufficient evidence to direct timely and targeted on-farm investigations. A shift in focus from testing the microbiological quality of the produce to investigating the processes and practices through the supply chain and sampling the farm environment is recommended.
