RESUMO
Mycotoxins have several toxicological implications. In the present study, we evaluate the presence of aflatoxin B1 (AFB1), ochratoxin A (OTA), and fumonisin (FB1) in paddy rice, polished rice, and maize from the fields and markets in Nayarit State (Mexico). The results indicated the presence of AFB1 in 21.21% of paddy rice samples and 11.11% of market maize samples. OTA was present in only 3.03% (one sample) of paddy rice samples. FB1 was detected in 87.50% and 88.88% of maize samples from field and market, respectively. The estimated human exposure was calculated for FB1 using the probable daily intake (PDI), which suggested that FB1 could contribute to the development of diseases through the consumption of contaminated maize. Positive samples indicated that some rice and maize samples were not suitable for human consumption. Further efforts are needed to continue monitoring mycotoxins and update national legislation on mycotoxins accordingly.
