\textbf{Abstract}
\begin{abstract}
\normalsize{
To obtain maximum genetic potential, feed nutrient supply must meet the requirements of the animals. Therefore feed plays an important role in animal production. However not only feed quantity but also feed quality should be considered. Phatthalung province is a hot spot for animal production in the southern part of Thailand, which has an ideal climate for fungi growth and aflatoxin production. However the data on the aflatoxin contamination of commonly used feedstuffs in the area are still limited.  The objective of this research was to study the level of aflatoxin contamination in feedstuffs in Phatthalung province. A total of 98 feedstuff samples were collected from farms and feedmills in Patthalung province. The aflatoxin contamination in the samples was analysed according to the Enzyme-Linked Immunosorbent Assay (ELISA) method using the DOA-Aflatoxin ELISA Test Kit. It was found that \mbox{71.43\,\%} of 98 feedstuffs samples which consisted of corn, broken rice, rice bran, cassava leave, ground cassava, cassava chip, cassava waste, palm kernel meal, soybean meal, full fat soybean and fish meal presented the contamination of aflatoxin. \mbox{100\,\%} of corn samples showed positive on aflatoxin analysis; whereas the other feedstuffs sample was found contaminated with aflatoxin in the range of 54--\mbox{76\,\%} of total sample of each feedstuffs. The average of aflatoxin contaminated in the feedstuffs are as follows; corn (29.74 ppb) $>$ ground cassava (27.40 ppb) $>$ palm meal (26.85 ppb) $>$ full fat soybean (24.46 ppb) $>$ cotton meal (24.14 ppb) $>$ broken rice (23.39 ppb) $>$ cassava chip (23.37 ppb) $>$ rice bran (23.02 ppb) $>$ fish meal (22.42 ppb) $>$ soybean meal (22.02 ppb) $>$ cassava leave (18.54 ppb) $>$ cassava waste (7.75 ppb). The highest contamination level found in this study was in corn (48.13 ppb).Though, the level of aflatoxin contamination found in this study did not exceed the maximum level established in Animal Feed Quality Control Regulation, the percentage of contamination is high. Therefore the awareness and surveillance of mycotoxin is essential to guarantee high animal performance, and the safety of food.
