Abstract :

Aflatoxins are secondary products of fungi that reduce food storage and change the organoleptic properties of agricultural products. The purpose of this study is to investigate the occurrence of aflatoxin B₁ in livestock and poultry feed produced in Qom county by ELISA method. In this study, 50 samples of livestock and poultry feed, including 25 samples of livestock feed and 25 samples of poultry feed, were randomly sampled from the production centers of these products in Qom County and transferred to the food hygiene laboratory of the Faculty of Veterinary Medicine of Shahrekord Azad University. The results showed that all animal feed samples and all poultry feed samples were contaminated with aflatoxin B₁. Among the sampled poultry feed, the amount of aflatoxin B₁ was 1.62 and 7.10 μg/kg, respectively. The results showed that among the 50 animal and poultry feed samples examined, none exceeded the national standard of Iran; Therefore, no pollution more than 30 μg/kg was observed in any of the samples. Statistical analysis of the poultry feed sample showed that the average contamination with aflatoxin B₁ was calculated as 3.74±0.95 and the variance of the samples was also 0.96. In the current research, it was shown that the level of aflatoxin contamination is in a favorable condition, but in order to reduce aflatoxin and reduce the risk of hazards for food safety and health of consumers, strict standards should be set for substances prone to aflatoxin formation.
