Inhibition of Listeria monocytogenes by Carnobacterium piscicola in vacuum-packaged cooked chicken at refrigeration temperatures

Listeria monocytogenes inhibition by bacteriocinogenic Carnobacterium piscicola DX or nonbacteriocinogenic C. piscicola 2818 was examined in vacuum-packed minimally processed chicken cubes with gravy at 4, 8 and 15C. C. piscicola DX and C. piscicola 2818 at 104 CFU/g were coinoculated individually w...
