@entity18639 contamination of home-grown @entity4336 in high-risk areas for esophageal and XXXX in China.

@entity18639 ( @entity18640 ) is reportedly the causative agent of several animal @entity37767 and has etiologically been linked to @entity1 oesophageal and @entity96 in certain areas of South Africa and China. To study a possible relationship between exposure to @entity18640 and @entity1 @entity5 risk, the current status of @entity18640 contamination in food samples in Huaian and Fusui, where incidences of oesophageal and @entity96 are amongst the highest in China, was investigated. A total of 259 @entity4336 samples were collected from individual households in five villages of different townships in Huaian during December 2001 and December 2002, and in four villages of different townships in Fusui during May 2001 and May 2002. @entity4336 samples were also collected from individual households in two villages in Huantai, an area with low incidences of both @entity5 . Enzyme-linked immunosorbent assays (ELISA) and immunoaffinity-HPLC methods were used for @entity18640 analysis. In @entity4336 samples from Huaian, @entity18640 was detectable in 95.7% (112/117) of the samples, with an average of 2.84 mg kg-1 (range 0.1-25.5 mg kg-1). @entity18640 was detected in 83.0% (78/94) of the Fusui samples, with an average of 1.27 mg kg-1 (range 0.1-14.9 mg kg-1), and in 83.3% (40/48) of Huantai samples, with an average of 0.65 mg kg-1 ranging from 0.1 to 5.7 mg kg-1. The level of @entity18640 in @entity4336 samples from Huaian was significantly higher than from Huantai (P < 0.001). In addition, 47 of 112 (42.0%) positive Huaian samples had @entity18640 level greater than 2.0 mg kg-1, which was significantly higher than 10.0% (4/40) of Huantai samples (P < 0.001). Furthermore, variations were found between samples collected in different years and different villages. The high contamination rates of @entity18640 found in food from these areas, along with previous reports, suggest a possible contributing role of @entity18640 in @entity1 esophageal- and hepato- @entity105 .
