Similar non-neoplastic lesions are found in mice, guinea pigs, and rabbits; however, hepatic necrosis in guinea pigs is typically centrilobular and in rabbits is centrilobular to midzonal. By general agreement this definition excludes the toxins produced by macrofungi (the mushrooms), and compounds that cause disease only in plants or lower animals such as insects. The major mycotoxins of importance in human and animal health are aflatoxins, ochratoxin A, fumonisins, deoxynivalenol, patulin, and zearalenone. mycotoxin, naturally occurring metabolite produced by certain microfungi (i.e., molds) that is toxic to humans and other animals. Much more research is needed to define the extent to which this mycotoxin adversely affects the food supply, and its involvement in animal and human diseases.
