One of the oldest and richest sources of nutrition, fish and seafood are today a critical topic in food integrity and safety. Whether shipped fresh, frozen, canned or as a key ingredient in prepared food, these products are particularly and uniquely sensitive to foodborne illnesses. Caught wild or raised in aquaculture farms, fishery products are high moisture, making these particular susceptible to pathogens.
