Abstract

Secondary metabolites of filamentous mold are mycotoxins, which in some situations can develop on foods
derived from plants or from animals. Fusarium, Aspergillus, and Penicillium are the most common types of
mold that produce mycotoxins and also often contaminate human food and animal feed. Aflatoxins including
aflatoxin B1, B2, G1 and G2 are produced by A. flavus and A. parasiticus. M1 and M2 aflatoxins are
found in dairy products. In this study, we used PCR to detect and identify mycotoxigenic fungi material in
foods from traditional markets and supermarkets in Surabaya, Indonesia. Samples of chicken meat from a
traditional market and from a supermarket (10 pieces each) were placed in a conical tube and crushed in PBS.
The crushed samples were centrifuged and the supernatants were cultured on potato dextrose agar (PDA)
media and observed using a reverse microscope. DNA was isolated from cultured samples and subjected
to PCR with primers specific for genes encoding aflatoxins. Interestingly, we revealed that the Polymerase
Chain Reaction (PCR) analysis showed A. flavus and A. ochraceus were present on chicken meat sold at
traditional markets and supermarkets. In sum, enhanced precautions may be needed to ensure that foods sold
in traditional markets and supermarkets are free from molds that have the potential to produce mycotoxins.
Further studies are needed to detect and identify the prevalence of mycotoxins in the food supply.
