To study the deoxynivalenol (DON) contamination status in wheat flour of China in 2013. Stereotypes packaged or bulk wheat flour samples sold in 28 provinces were collected in a random sampling way. The concentration of DON in each flour wheat sample was measured by high performance liquid chromatography. The results were statistically analyzed and evaluated. A total of 5678 wheat flour was detected. The detection rate of DON was 58.74%. The excessive rate of the standard of DON was 4.60%. The average content of DON was 317 µg/kg. The content range of DON was 0-56.1 mg/kg. DON pollution is relatively common in wheat flour of China in 2013, but the excessive rate is not high. The degree of pollution in each area is different. The excessive rate of DON, which was associated with the local temperature and humidity conditions, in wheat flour sold in east, southwest and northwest area is relatively high. Pollution level of DON in wheat flour in 2013 is consistent with those in 2010 and 2011, but lower than the monitoring results in 2012.
