[Contamination of cotton seeds and of cotton seed cake by aflatoxin].
Following the discovery of aflatoxin M in cow's milk in the previous study, the contamination with aflatoxin of cotton-seed and cotton-seed cake which constitute the principal feed of local animals was measured. The samples were taken from 2 factories. The grain from the 1st factory was grown in the centre of the country in dry climate, and those from the 2nd source originated from the humid region of the north of Iran. The grain and cotton-seed cake from the 1st factory did not contain aflatoxin before storage. During storage the sample contamination amount and percent increased with time in both regions, with the dry less than the humid. In conclusion, Iranian cotton-seed and cotton-seed cake appear to be contaminated with aflatoxin B in 2 processes. The 1st is aflatoxin contamination before harvest, in the humid region of Iran; the 2nd is general storage aflatoxin contamination in both regions in which humidity and length of storage appear to be the principal factors.
