RESULTS: All feed samples resulted to be contaminated with OTA at levels ranging from 0.22 to 38.4 mu g kg(-1). The OTA concentrations found in organic feed samples were significantly higher (P < 0.05) than those found in conventional feed samples. All serum samples resulted to be contaminated with OTA at levels ranging from 0.03 to 6.24 ng mL(-1). The OTA concentrations found in organic serum samples were significantly higher (P < 0.001) than those found in conventional serum samples.
BACKGROUND: A survey was carried out on conventional (n = 11) and organic (n = 4) swine farms in northwest Italy in order to investigate the occurrence of ochratoxin A (OTA) in feed and serum samples collected from September 2006 to March 2009. Each farm was sampled twice and a total of 30 feed samples and 285 serum samples were collected. OTA levels were determined through extraction, immunoaffinity column purification and high-performance liquid chromatography analysis coupled with fluorimetric detection.
