Research – Risk assessment of norovirus and hepatitis A virus in strawberries imported into China

Wiley Online

Abstract

Norovirus (NoV) and hepatitis A virus (HAV) pose a considerable health risk worldwide. In recent years, many cases of virus infection caused by virus-contaminated strawberries have occurred worldwide. This study applied a critical control point system to analyze the main hazards during the production and marketing of strawberries imported into China and explore the key control points in the whole process. To further evaluate the risks in the supply chain, the established quantitative microbial risk assessment (QMRA) was used to determine the probability that residents would be infected with viruses after consuming imported strawberries. It was found that the risk of virus contamination from imported strawberries was low, and the virus contamination mainly results from water resources and personnel. This research helps the regulatory authorities formulate strategies to ensure the long-term microbial safety of imported strawberries. In addition, the methods may prove useful in evaluating the risks of other agricultural produce.

USA – Marco’s Italian Restaurant linked to Hepatitis A scare

Food Poison Journal

The Maine Center for Disease Control and Prevention (Maine CDC) has identified a case of hepatitis A in a Lewiston food service worker. Hepatitis A is a contagious liver disease caused by the hepatitis A virus. It can spread through person-to-person contact or by consuming contaminated food or water.

The individual worked during their infectious period at Marco’s Italian Restaurant, 12 Mollison Way in Lewiston on the following dates: September 11, 13, 15–16, 18, 20-22, 25, and 27-28, 2023. Anyone who purchased and/or ate food or drink from this restaurant during these days could be at risk for hepatitis A infection. An infected person can spread the virus to others from about two weeks before symptom onset until one week after symptoms begin.

USA -Outbreak Investigation of Hepatitis A Virus Infections: Frozen Strawberries (February 2023)

FDA

Current Update

September 15, 2023

The FDA and CDC, in collaboration with state and local partners, investigated an outbreak of hepatitis A virus infections linked to frozen organic strawberries imported from Baja California, Mexico. FDA’s traceback investigation identified a common supplier of organic strawberries. Strawberries used by this supplier were imported from certain farms located in Baja California, Mexico, in 2022. Additionally, the strain of hepatitis A virus causing illnesses this year is genetically identical to the strain that caused the outbreak of hepatitis A virus infections in 2022, which was linked to fresh organic strawberries imported from Baja California, Mexico, and sold at various retailers. Due to the matching strains of hepatitis A, investigators considered traceback and epidemiological data from the 2022 and 2023 outbreaks. When both data sets were considered together, investigators found that a single farm was associated with the distribution of strawberries consumed by ill people in both outbreaks. This single farm supplied strawberries to multiple importers across both outbreaks and some recipients processed fresh strawberries into the frozen berries consumed in the 2023 outbreak.

As of September 15, 2023, no additional illnesses have been reported and CDC has announced that this outbreak has ended. FDA’s investigation is complete.  While the outbreak has ended, FDA continues to work closely with competent authorities in Mexico through the established Food Safety Partnership to investigate potential source(s) of contamination within the implicated region and to proactively implement prevention strategies for growers ahead of the next growing season. FDA also intends to consider using additional tools, such as import screening and sampling, for strawberries grown and harvested in Baja California, Mexico, during the next growing season.

USA – Health officials warn of Hepatitis A exposure at Michigan concert venue

Food Safety News

In Michigan, the Oakland County Health Division is reporting a suspected case of hepatitis A associated with the Ivy Lounge at Pine Knob Music Theatre in Clarkston.

The Health Division advises all season members, their guests, and staff who consumed food at the Ivy Lounge between Aug. 26 and Sept. 8 to monitor for symptoms and, if unvaccinated for hepatitis A, to get vaccinated as soon as possible.

“The risk of transmission in this specific situation is low,” said Dr. Russell Faust, Oakland County medical director. “If you have not been vaccinated, get vaccinated. If given within 14 days after exposure, the vaccine can prevent the disease.”

Unvaccinated people who were possibly exposed to hepatitis A from Sept. 1-8 at the Ivy Lounge are encouraged to receive the vaccine by the 14-day deadline.

FAO and WHO plan meeting on foodborne viruses

Food Safety News

The UN Food and Agriculture Organization (FAO) and World Health Organization (WHO) are set to hold an expert meeting on viruses in food later this month.

The Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA) event, at FAO headquarters in Rome on Sept. 18 to 22, will work on food attribution, analytical methods, and indicators of viruses in foods.

United States-based experts proposed for the meeting are Donald Schaffner, of Rutgers University; Xiang-Jin Meng, at Virginia Tech; Kali Kniel, from the University of Delaware; Lee-Ann Jaykus, at North Carolina State University; and Jacquelina Williams-Woods of the FDA.

In 2022, the Codex Committee on Food Hygiene (CCFH) asked JEMRA to provide scientific advice to inform a review of guidelines established in 2012. This was due to emerging issues associated with foodborne viruses and scientific developments.
