Abstract

Cow's milk represents a potential health risk for consumers. The objective of this work is to assess the sanitary quality of raw cow's milk produced and consumed by the populations of Daloa. For this purpose, a total of 30 raw milk samples were collected from 3 raw cow's milk extraction points in the city of Daloa. Mycotoxins were determined using gas chromatography. The results showed that 100% of the analyzed samples were contaminated with aflatoxin M1 (AFLM1). These results indicated that the aflatoxin M1 levels in the analyzed samples exceeded the maximum limit (ML) set by European regulations. To assess the risk of contamination for the population of Daloa, a survey was conducted among consumers of raw cow's milk. A total of 388 individuals were interviewed to gather their opinions. The survey involved a form with questionnaires related to the objectives of the study. This form provided information on identity, marital status, consumption patterns, frequency, quantity, and the socio-economic characteristics of the consumers. The results showed that the risk of liver cancer related to the consumption of raw cow's milk in the city of Daloa is approximately 36.08% to 36.16%; representing 36,080 to 36,150 cases per 100,000 inhabitants. Thus, to ensure consumer safety, good hygiene practices in the preservation of feed for cattle and the construction of enclosures for them must be implemented.
