Abstract

Refrigerated mixtures of raw milk provided by a dairy which was supplied by farms from west and central Spain were tested for the presence of Listeria microorganisms. A total of 95 samples were taken at regular intervals over a 16-month period. Listeria grayi was isolated from 89.5% of the samples, Listeria monocytogenes s. str. from 45.3%, Listeria innocua from 15.8%, Listeria welshimeri from 3.1%, and Listeria seeligeri from 1.05%. Listeria ivanovii, Listeria murrayi, and Listeria denitrificans were not isolated.
