Aflatoxin contamination in corn utilized for swine feeding

Abstract

Aflatoxin content and free water level of 420 samples of corn utilized in swine feeding were analysed. Corn samples were collected monthly from swine farms, feed factories and agricultural cooperatives, in Santa Catarina state, Brazil, during April 1985 to March 1988. The period from January to August presented the highest tree water and aflatoxin contamination levels, while the period from September to December presented the lowest levels. It was also observed that corn from swine farms presented higher contamination and tree water levels than corn samples collected from teed factories and agricultural cooperatives.
