Prevalence and Risk Assessment of Aflatoxin in Iowa Corn during a Drought Year.
Warm temperatures and drought conditions in the United States (US) Corn Belt in 2012 raised concern for widespread aflatoxin (AFL) contamination in Iowa corn. To identify the prevalence of AFL in the 2012 corn crop, the Iowa Department of Agriculture and Land Stewardship (IDALS) conducted a sample of Iowa corn to assess the incidence and severity of AFL contamination. Samples were obtained from grain elevators in all of Iowa's 99 counties, representing nine crop reporting districts (CRD), and 396 samples were analyzed by IDALS using rapid test methods. The statewide mean for AFL in parts per billion (ppb) was 5.57 ppb. Regions of Iowa differed in their incidence levels, with AFL levels significantly higher in the Southwest (SW; mean 15.13 ppb) and South Central (SC; mean 10.86 ppb) CRD (p < 0.05) regions of Iowa. This sampling demonstrated high variability among samples collected within CRD and across the entire state of Iowa in an extreme weather event year. In years when Iowa has AFL contamination in corn, there is a need for a proactive and preventive strategy to minimize hazards in domestic and export markets.
期刊介绍：
International Journal of Food Science is a peer-reviewed, Open Access journal that publishes research and review articles in all areas of food science. As a multidisciplinary journal, articles discussing all aspects of food science will be considered, including, but not limited to: enhancing shelf life, food deterioration, food engineering, food handling, food processing, food quality, food safety, microbiology, and nutritional research. The journal aims to provide a valuable resource for food scientists, food producers, food retailers, nutritionists, the public health sector, and relevant governmental and non-governmental agencies.
