CURRENT
RESEARCH
A
central theme in the program is the development, use and evaluation
of natural antimicrobials to extend shelf-life and safety
of meats (fresh, cured and fermented). This necessarily involves
work to understand how the inhibitors work so that inhibitor
combinations can be optimized. Interest includes organic acids,
essential spice oils, fatty acid derivatives, as well as a
variety of natural bacterial, carnobacteria, other spoilage
bacteria and pathogens (Listeria, E.coli O157:H7). Work will
evaluate surface application of inhibitors to meat and involve
development of active packaging film materials to delay spoilage
and improve product safety. Collaborative work includes a
variety of studies in food microbiology (eg. bacterial spores
in flour, safety of cheese and chicken nuggets) as well
as studies on survival and spread of zoonotic bacteria among
animals and in their environment, as well as bacterial resistance to antibiotics.
