There are three distinct types of molds: allergenic, pathogenic, and toxigenic. Toxigenic molds pose the most serious health risk to both humans and animals because they have aflatoxins.
Recently, there were news reports of pet food recalls. The food was recalled because it was contaminated with aflatoxins.
Aflatoxins are naturally occurring mycotoxins produced by the mold Aspergillus. Aspergillus flavus and Aspergillus parasiticus are two of the most toxic and most carcinogenic molds leading to many health risks, including several types of cancer.
According to Veterinary Practice News “aflatoxins are produced on peanuts, soybeans, corn and other cereals in the field or during storage when moisture content and temperatures are sufficiently high for mold growth. High doses of aflatoxins result in severe hepatocellular necrosis, and prolonged low dosages result in reduced growth rate and liver enlargement. Pets that have consumed the affected product and are exhibiting symptoms of illness including sluggishness or lethargy combined with a reluctance to eat, vomiting, yellowish tint to the eyes or gums, or diarrhea should be seen by a veterinarian.”
