Original Text: Mycotoxin


Dried Distiller’s Grains with Soluble (DDGS) is a by-product of the distillery process, particular produced by corn-ethanol fuel. Usage of DDGS to replace for corn as animal feed is of widely interest. Mycotoxins contamination in DDGS may harm to animal health. However, little data of co-occurrence of mycotoxins contamination in DDGS, particularly at the end user (farmer) was reported. The aim of this study was conducted to simultaneously detect six mycotoxins including deoxyninalenol (DON), zealarenone (ZON), T-2 toxin (T2), fumonisin B1 (FB1), fumonisin B2 (FB2) and beauvericin by LC-MS/MS. The data present a prevalence of mycotoxins contamination in corn- DDGS as animal feed in Thailand.
Total of 59 corn-DDGS samples collected from swine farms in central region of Thailand during 2009-2010 were tested. As depicted in the table 1, results showed number of samples of DON, ZON, T2, FB1, FB2 and beauricin at variation levels. Additionally, 50% of samples found co-occurrence of five mycotoxins. None of T-2 toxin was found. Fumonisin is obviously predominant toxin in corn-DDGS. Interestingly, beuvericin could be detected in all fumonisin contaminated-samples.

Revised Text:

Dried Distiller’s Grains with Soluble (DDGS) is a by-product of the distillery process, particularly the production of corn-ethanol fuel.

Use of DDGS to replace corn as an animal feed is of wide interest. Mycotoxin contamination of DDGS may harm animal health, however, little data of co-occurrence of mycotoxin contamination in DDGS, particularly by the end user (farmers), has been reported.

The aim of this study was to simultaneously detect six mycotoxins, including; deoxyninalenol (DON), zealarenone (ZON), T-2 toxin (T2), fumonisin B1 (FB1), fumonisin B2 (FB2) and beauvericin by LC-MS/MS. The data presents a prevalence of mycotoxin contamination in corn- DDGS used as animal feed in Thailand.

A total of 59 corn-DDGS samples collected from swine farms in the central region of Thailand during 2009-2010 were tested. As depicted in table 1, results showed a number of samples of DON, ZON, T2, FB1, FB2 and beauricin at variation levels. Additionally, 50% of the samples showed co-occurrence of five mycotoxins. None with T-2 toxin were found.

Fumonisin is obviously the predominant toxin in corn-DDGS. Interestingly, beuvericin could be detected in all fumonisin contaminated-samples.
