Summary

CULTURES OF 3 LISTERIA MONOCYTOGENES SEROTYPES AND 3 SALMONELLA SPP WERE APPLIED TO THE EXTERIOR SURFACES OF WAXED CARDBOARD OR PLASTIC MILK CONTAINERS. CONTAMINATION SITES WERE SAMPLED WITH PREMOISTENED COTTON SWABS DURING 14 D OF REFRIGERATION. UNSTRESSED CELLS OF LISTERIA SURVIVED UP TO 14 D ON THE SURFACES OF WAXED (1 SEROTYPE) AND PLASTIC (3 SEROTYPES) CONTAINERS. HEAT-STRESSED CELLS OF ALL 3 SEROTYPES OF LISTERIA SURVIVED FOR 2 D ON BOTH TYPES OF CONTAINERS. ONE SEROTYPE SURVIVED FOR 4 D, BUT ONLY ON PLASTIC CONTAINERS. UNSTRESSED CELLS OF ALL 3 SALMONELLA STRAINS SURVIVED UP TO 14 D ON BOTH TYPES OF CONTAINERS. HEAT-STRESSED SALMONELLA STRAINS SURVIVED UP TO 2 D (WAXED CONTAINERS) AND 4 D (PLASTIC CONTAINERS).
