PRESUMPTIVE DETECTION OF AFLATOXINS IN PEANUTS MARKETED IN RECIFE, PE, BRAZIL

Abstract

Mycotoxins are natural contaminants difficult to control in food. It is estimated that about 25% of all agricultural products in the world are contaminated by these substances. Aflatoxin is the most known mycotoxin for its toxic effects in
humans and animals. Based on the risks to which the population is exposed, a study for the presumptive identification of the presence of aflatoxins in industrialized peanuts seeds, purchased at supermarkets, and in samples collected in Boa Viagem beach, in Recife, state of Pernambuco was conducted. Applying the thin layer chromatography technique (TLC), the presence of aflatoxin was detected in all six analyzed samples. Aflatoxin B was found in samples of processed peanuts, and in fresh samples. Regarding the G subtype, it was observed only in one of the roasted peanuts samples. The complete elimination of aflatoxins in food is virtually impossible to occur. Therefore, the appropriate precautions should be taken, seeking to reduce the maximum aflatoxin levels in human food and animal. In addition to government oversight, food industry and the all people should also help to ensure better food safety.
