Surveying the levels of mold and aflatoxin in maize and peanut in some households in Ea H’Leo, Cu M’Gra, Krong Pac districts in Daklak province in 2016

Abstract

Agricultural products are contaminated with mold and aflatoxin, which not only reduces the value of agricultural products but also affects the health of people and animals when using such agricultural products. The survey was conducted on 150 samples (maize, peanut) in several households in Ea H'leo, Cu M'Gar, Krong Pac - Dak Lak districts, by the method of identifying mold Aspergillus flavus (A. flavus) and Aspergillus parasiticus (A. parasiticus) according to 52 TCN-TQTP 0001:2003 and 52 TCN-TQTP 0009:2004 and aflatoxin quantification according to TCVN 7596 - 2007. The results showed that among 150 samples (maize, peanut) in the analysis, there were (48.7%) samples contaminated with mold exceeding the allowable level, for maize (56.6%), peanuts (33.3%). There was the presence of A. flavus in maize sample (14.1%) and peanut samples (11.8%), and A. parasiticus was not found in the samples. While, the prevalence of AF contamination in agricultural products (maize, peanuts) accounted for (12.7%). In which, the rate of AF contamination in maize samples was 17.2%, contaminated rate of peanut samples was 3.9%; Aflatoxin contaminated samples exceeded the allowable limit for maize was 14.1% and this rate of peanut sample was 3.9%.
