Raw seafood regularly carries Listeria as it is ubiquitous in the environment. Cold smoked salmon is particularly at risk. Cooked seafood can become contaminated during processing.

Listeria causes Listeriosis, the leading cause of death due to foodborne illness. 1 in 5 people die as a result. People at risk are the young, the old and the immunocompromised. It can also cause still births.

Contamination with Listeria monocytogenes is a constant threat to the fish industry. Cleaning techniques like heat treatment can be unsuitable because they alter the product.


Raw and cooked processed seafood rely on PhageGuard to kill Listeria.

“We had a recall a few years back and it cost us in excess of well over $100,000. The FDA came in, consultants came in, we lost business. Basically it was a mess. We met Micreos at a seafood show shortly after, they came over and we started using Listex. That was almost 10 years ago.

“Listex only targets Listeria, leaving everything else the way it is supposed to be. It’s the only product I have come across that does this for us. I sleep better knowing I am controlling Listeria and not flying blind.” – Prominent East Coast Salmon Producer
