One of the most common intoxications in poultry is Aflatoxicosis, contamination with Aflatoxine. Molds like Aspergillus and Penicillium can produce aflatoxins. Usually aflatoxins are formed when raw materials or feeds are stored under non-optimal conditions. However, they can also be formed already on the fields, when the growing conditions are wet and warm.
One of the first signs of aflatoxicosis is a reduced appetite, but the main problem is mortalitty. One of the clinical signs is an enlarged yellow liver. Athough especially turkeys and ducks are sensitive, aflatoxicosis can occur in chickens as well.
