Growth of Brochothrix thermosphacta inground beef following treatments with nisin in calcium alginate gels

Vacuum packed beef bacteria. Sampling prep using Seward Stomacher®

The Stomacher® 400 was used to blend ground beef for two minutes, as part of the study. The study found that the growth of B. thermosphacta could not be effectively suppressed for 14 days, the application of nisin in alginate gels to meat surfaces does afford some protection against undesirable bacteria when these surfaces are processed into ground beef.
