The battle against Listeria has a new weapon, a bioprotective culture designed to fight the bacteria in salami and other dried, fermented sausages. B-LC-20, from Chr. Hansen, is a natural solution that uses lactic acid bacteria to fight Listeria without changing the taste or smell of the food. Costs are comparable to traditional meat cultures used for flavor development, while guarding against the costs of battling the spread of the deadly bacteria. Chr.
