A recent study investigated listeriosis outbreaks in Germany using whole genome sequencing (WGS) and patient interviews. The researchers were able to link a significant number of listeriosis cases to smoked and graved salmon products that were contaminated with Listeria monocytogenes. The findings highlight the need to improve hygiene practices in facilities that process uncooked salmon products, as well as to better inform the public and vulnerable populations of the risk of contracting listeriosis from smoked and graved salmon.
