Abstract/ Executive Summary:

John Deere and Frugal Moisture meter were compared with that of Indosaw standard. Frugal moisture meter was similar to the Indosaw standard but John Deere moisture meter were, on average, 2% higher than the standard. It is believed the John Deere model can be recalibrated to provide accurate results.Baseline survey on mycotoxins among 200 households of two districts of Bangladesh through the questionnaire indicate that the farmers were familiar with grain discoloration due to mold contamination but they did not have any idea about mycotoxins production on grains. Grain samples, one kg from each of 200 households were collected during May and June (Boro 2015), 119 had moisture content >14% and 37 had moisture content >20%. Purity, discoloration, mold invasion, insects and germination were assessed in the laboratory. Inert matter was 10% in 142 samples and >15% in 15 samples. Molds were associated with grain discoloration. Samples with high moisture content had higher quantity of moldy grains and stored pests. There was 25% grain discoloration of which 18% were moldy when the moisture content was >20%. Blotter incubation test revealed 19% incidence of Aspergillus growth on the 19% of the grains and Fusarium growth in 9% of the grains and produce Aflatoxins produced by Aspergillis and fumonisins by Fusarium were detected in rough rice of India (Reddy et al., 1986). Detection and quantification has of these two mycotoxins have not yet been done in Bangladesh. Through the present study the paddy samples will be analyzed by USDA Romer Lab test kit strips to create a national database on mycotoxins in paddy of Bangladesh.

Program Area: Pest Management

Commodity: Diseases

Objectives:

Possibility of mycotoxins contamination on paddy during post harvest operations of Boro paddy in Bangladesh

Methodology:

Two hundred farm households were selected four villages of Phulpur upazila of Mymensingh district and four villages of Monirampur upazila of Jessore district of Bangladesh. The guidelines of the USAID project “Feed the Future Post Harvest Loss Reduction Lab (PHLIL)” was followed for farm house hold selection. A total of 200 submitted samples of grains, @ one sample/farm house hold were collected. The samples were taken to the Mycotoxins Lab, BAU and preserved for further study. Moisture contents of the 200 paddy samples were determined by the USDA John Deere digital moisture meter following the instruction on the Guide Book. PHLIL has donated two types of digital moisture meters to the Mycotoxins Lab-BAU. The accuracy of John Deere and Frugal Sensor moisture meter was compared with that of Indosaw standard moisture meter. Five samples were taken from each of BADC and Ispahani Seed Company. Moisture contents were determined by the three moisture meters.

Achievement/Findings:

Grain samples of the farmers of Bangladesh had high moisture content that enhanced the growth of molds. The farmer samples collected from 200 farm households of Bangladesh with high moisture content had high amount of discolored grains, insert matter and insects. Grains are mostly susceptible to mycotoxins production because they are sources of carbohydrates, or sugars. The nutrients of food product invite risk of contamination by the mold fungi. These fungi produce secondary metabolites, mycotoxins. Consumption of low mold infected grains not only toxic but can cause mal-nutrition due deterioration of nutrient value. There has been no research about detection and quantification of the mycotoxins in rough grains of paddy samples of the farmers in Bangladesh. Thus, the paddy samples will be analyzed by Romer lab kit strips for detection and quantification of Aflatoxins and Fumonisin as well nutrient status of the mold infected grains will be determined by biochemical test. Dedicated facilities will be established to develop a National Mycotoxins Lab in Bangladesh
