Summary

A SURVEY OF FROZEN MILK-PRODUCT PLANTS IN CALIFORNIA WAS CONDU CTED TO DETERMINE PREVALENCE OF LISTERIA AMONG PLANTS AND WITHIN SPECIFIC AREAS IN PLANTS. ASSOCIATION OF POSSIBLE FACTORS CONTRIBUTING TO THE PRESENCE OF LISTERIA WAS ANALYZED. OF 922 SAMPLES, 111 (12%) WERE POSITIVE FOR LISTERIA. L. MONOCYTOGENES AND L. INNOCUA WERE THE ONLY SPECIES ISOLATED. THE TYPE OF PRODUCT AND TYPE OF PASTEURIZATION DID NOT INFLUENCE RECOVERY OF LISTERIA FROM A PLANT.

THE HIGHEST RECOVERY RATES OF LISTERIA WERE IN FLAVOURING, FREEZING, INGREDIENT BLENDING AND PACKAGING AREAS.
