Frozen corn and possibly other frozen vegetables are the likely source of an outbreak of Listeria monocytogenes that has been affecting Austria, Denmark, Finland, Sweden, and the United Kingdom since 2015.
Experts used whole genome sequencing to identify the food source, which initially was thought to be limited to frozen corn. As of 8 June 2018, 47 cases including nine deaths had been reported.
The same strains of L. monocytogenes have been detected in frozen vegetables produced by the same Hungarian company in 2016, 2017 and 2018. This suggests that the strains have persisted in the processing plant despite the cleaning and disinfection procedures that were carried out.
The available information confirms the contamination at the Hungarian plant. However, further investigations, including thorough sampling and testing, are needed to identify the exact points of environmental contamination at the Hungarian plant. The same recommendation applies to other companies belonging to the same commercial group if environmental contamination is detected.
On 29 June 2018, the Hungarian Food Chain Safety Office banned the marketing of all frozen vegetable and frozen mixed vegetable products produced by the affected plant between August 2016 and June 2018, and ordered their immediate withdrawal and recall. This last measure is likely to significantly reduce the risk of human infections and contain the outbreak. All freezing activity at the plant has been stopped.
New cases could still emerge due to the long incubation period of listeriosis (up to 70 days); the long shelf-life of frozen corn products; and the consumption of frozen corn bought before the recalls and eaten without being cooked properly.
To reduce the risk of infection, consumers should thoroughly cook non ready-to-eat frozen vegetables, even though these products are commonly consumed without cooking (e.g. in salads and smoothies). This applies especially to consumers at highest risk of contracting listeriosis – such as the elderly, pregnant women, newborns and adults with weakened immune systems.
Erie Meat Products Ltd. is recalling Druxy’s Fresh Deli Revolution brand Seasoned Cooked Roast Beef from the marketplace due to possible Listeria monocytogenes contamination. Consumers should not consume the recalled product described below.
Poppies International, Inc. of Battleboro, NC is issuing a voluntary recall of selected products that were made during March 5-9, 2018 because they have the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short term symptoms such as fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.
Cases of listeriosis will continue to occur up to four weeks or longer after the recall of the implicated foodstuffs, as the incubation period for listeriosis can be as long as 21 days with a reported maximum of 70 days.
