Aflatoxins: Finding solutions for improved food safety: Animals and aflatoxins

The paper examines the effects of aflatoxins on livestock and the pathways through which contamination in animal feed can impact animal health, productivity, and human food safety. Aflatoxins are commonly found in feed ingredients such as cereals, oil cakes, and fishmeal, with particularly high risks in intensive livestock systems. Their effects vary by species, age, and environmental conditions, but can include acute toxicosis, chronic health problems, reduced growth and productivity, and weakened immune systems. These impacts result in significant economic losses for the livestock sector, particularly in developing countries where contamination levels frequently exceed regulatory limits and monitoring systems are limited.

The paper also highlights the transmission of aflatoxins into animal-source foods, especially milk, where even small transfer rates are concerning due to high consumption by vulnerable populations such as children. It outlines several control strategies for managing aflatoxins in animal feed, including the use of binding agents, blending, and decontamination methods, as well as the controlled use of contaminated feed for certain livestock. Despite available interventions, significant knowledge gaps remain regarding contamination levels, economic impacts, and effective management strategies. The study concludes that aflatoxins pose ongoing risks to both livestock production and public health, underscoring the need for improved monitoring, research, and cost-effective control measures.
