Can I eat seafood if I am at risk of Listeriosis?
All freshly cooked seafood is safe. Use immediately and store any left overs in the fridge for consumption within one day.
Fish and shellfish may be potential sources of Listeria, due to their harvest from natural environments where the bacteria can be found. However, it is more likely that Listeria may enter seafood products during and/or after processing through poor hygiene or manufacturing practices, or from subsequent handling of product. This is a special concern for those products that receive minimal or no heat treatment before consumption.
