In order to assess the mycological contamination of cattle feed, and the search for aflatoxin M1 in milk consumed in Algeria, we realized this work in eastern Algeria zone. Mycological results showed the presence of 247 fungal strains belonging to 9 genera (Aspergillus, Penicillium,Alternaria, Mucor, Rhizopus, Fusarium, Geotricum, Helminthosporium, Cladosporium), with a dominance of Aspergillus, followed by Penicillium. Among the foods analyzed, the concentrate appears to be the most contaminated substrate. The mycotoxicological study by HPLC, and involving a total of 47 milk samples (22 raw milk samples, 11 samples of pasteurized milk and
14 samples of dry milk), revealed five contaminated samples only one exceeding the standard described by European regulations (lyophilized milk 103ng/L). Biochemical and physicochemical analysis of raw milk showed that the samples tested meet the standards.
