Find me a Vet Aflatoxicosis Other Names: Turkey X-disease Aflatoxicosis is a type of poisoning from ingestion of aflatoxins in contaminated foods or poultry feed. They are potent hepatotoxins produced by Aspergillus flavus, A. The 4 aflatoxins of concern are B1, B2, G1, and G2. However, B1 is the most predominant and toxic.
Aflatoxin contamination is typically found in poor quality cheap poultry feeds which were made with contaminated ingredients, specifically corn. Aflatoxicosis can develop in both acute or chronic form. The chronic form is the most common and is the result of continuous ingestion of contaminated feed over a period of time.
This causes: Immunosuppression: Increases susceptibility to secondary infection by opportunistic pathogens. Reduced vaccine effectiveness: Decreases resistance against viral pathogens, increasing the risk of acquiring the disease they are getting vaccinated against. Gastrointestinal tract damage: Causes erosion and roughening of the gizzard lining, resulting in decreased absorption of nutrients, stunted growth, nutrient-deficient related syndromes, and lowered feed conversion.
Liver damage: The primary site of toxicity due to aflatoxins is the liver. Exposure causes hepatic lesions and enlargement of the liver as well as fatty liver. Production losses: Decreases egg production and egg quality in laying hens and hatchable eggs in breeding chickens. Preventative Absorbents.
Aflatoxin M1 is present in the fermentation broth of Aspergillus parasiticus, but it and aflatoxin M2 are also produced when an infected liver metabolizes aflatoxin B1 and B2. Nevertheless, they appear much less capable of causing mutagenesis than the unmetabolized toxin. The presence of those molds does not always indicate that harmful levels of aflatoxin are present, but does indicate a significant risk. The molds can colonize and contaminate food before harvest or during storage, especially following prolonged exposure to a high-humidity environment, or to stressful conditions such as drought. The native habitat of Aspergillus is in soil, decaying vegetation, hay , and grains undergoing microbiological deterioration, but it invades all types of organic substrates whenever conditions are favorable for its growth. Aflatoxins have been isolated from all major cereal crops, and from sources as diverse as peanut butter and cannabis.
Aflatoxicosis in Poultry

Find me a Vet Aflatoxicosis Groundnut peanut Poisoning, Turkey X-disease Aflatoxins AF are a class of mycotoxins , produced by fungal species of the genus Aspergillus flavus and parasiticus and Penicillium puberulum, that are often found in the ingredients used to make poultry feed. Foods known to be at a high risk of aflatoxin contamination include corn, cottonseed, peanuts, sorghum, tree nuts, and wheat. Crops can become contaminated with aflatoxins while growing in the field, during harvesting, transportation, mixing, or during storage. The FDA and the EU regulate the amount of aflatoxins present in human food, animal feed, and animal feed ingredients.
