OCCURRENCE OF AFLATOXIN M1 IN RAW MILK PRODUCED IN ARDEBIL OF IRAN

Abstract

Contamination of milk and dairy products to aflatoxin M1 is a risk for human and it can be a public heath concern. The aim of this study was to evaluate the presence of aflatoxin M1 in raw milk samples produced in Ardebil City (Iran) by ELISA (Enzyme Linked Immuno Sorbent Assay) technique. 122 samples of raw milk were collected from milk collecting centers and dairy plants in the region and aflatoxin M1 contamination was detected in all of milk samples. The mean concentration of aflatoxin M1 was 40.01ng/L and 14.75 percent of the samples had higher levels than the maximum recommended limits by ISIRI, European Community and Codex Alimentarius. With a view of the fact that milk is used by all the age groups including infants and children in the city of Ardebil, it is necessary to apply an ideal recommended limit to minimize the health hazard from aflatoxin M1 contamination in milk. Application of Good Agricultural Practices and Good Veterinary Practices by agriculture and also the Hazard Analysis and Critical Control Points (HACCP) system as a draft code of practice for preharvest and postharvest control of dairy cow’s feed and in milk and dairy products processing is effective.
