Abstract

Bulk tank milk from 160 producers was tested for Listeria monocytogenes at three monthly intervals over 1 year. Twenty‐five producers were positive, most on a single occasion, only seven were positive on three or more of the four samplings. Listeria monocytogenes numbers were low, usually <1 ml‐1, the highest was 35 ml‐1. All isolates were serotype 1, the use of multilocus enzyme electrophoresis on representative isolates gave nine different electrophoretic types, two have been associated with listeriosis in humans or animals, a further two had only been isolated from one other source (silage or faeces), while the majority (5) were unique to milk.
