A group of researchers found that a biodegradable, edible film made with plant starch and antimicrobial compounds may be used to control the growth of foodborne pathogens on seafood.
Seafood may be contaminated with bacterial pathogens, such as vibrio and salmonella, which are linked to gastrointestinal problems when consumed. Because both types of bacteria can survive long-term freezing conditions, the contamination of these bacteria is a concern for the seafood industry.

In this regard, professor of food science at Penn State university Catherine Cutter highlights that freezing does not kill bacteria but it may be helpful. She explained that when freezing food, ice crystals can form from the water in food and can act like "daggers" and pierce the bacterial cell wall, causing damage to the cell.
