To the Editor.—  Stephanie C. Crocco, PhD (242:548, 1979), of the American Medical Association Department of Food and Nutrition gave, in the QUESTIONS AND ANSWERS section, a summary of the current situation regarding aflatoxin contamination of grain. She has, however, failed to mention another source of aflatoxin introduction into the human food chain: the use of aflatoxin-contaminated cottonseed as feed for dairy cattle. Last year, aflatoxin appeared in high levels in milk in Arizona because of the use of this feed, and a major control effort is underway to prevent such an occurrence in the future. Physicians practicing in cotton-producing areas should be aware of this possible additional source of aflatoxin contamination in food.
