A Survey on Mycotoxin in Bangkok Food and Feed

Abstract

Commercial samples of food and feed collected at Bangkok markets were assayed for the presence of aflatoxins (B₁, B₂, G₁, G₂ and M₁), ochratoxins (A and B), citrinin, patulin and fumonisins (B₁, and B₂). Aflatoxins were detected in 11 samples from the total of 36 samples of peanut, corn, rice, coix seed and dairy products, aflatoxin B₁ was found in the range of 0.01-626 ppb. Eight corn and cereals products were assayed for ochratoxins, citrinin and fumonisins. No ochratoxins were detected. Citrinin were detected in 4 samples in the range of 0.4-4 ppb, while fumonisins were detected in 2 samples in the range of fumonisins B₁ 130-630 ppb, fumonisins B₂ 20-160 ppb. Five kinds of juice products were assayed for patulin. No patulin was detected.
