“…Further analysis confirmed the presence of oxytetracycline at low ppm value. Such cross-contamination phenomena usually happen, at feed mill level, as consequence of medicated and not medicated feeds production on the same line [8].…”

Oxytetracycline (OXY) is a broad-range antimicrobial routinely used in pig production, at doses in the range of few g/kg of medicated feed, during the weaning period. It could persist at ppm level in pig liquid manure that routinely is used for organic fertilisation. In the present work we describe a methodology to study OXY environmental fate in arable land where crops are cultivated for animal feeding purposes. A liquid-liquid extraction followed by metal chelate affinity chromatography was applied to environmental samples of manures and soils drawn within a case-control study. Extracts were then analysed by high performance liquid chromatography with UV/DAD detection, using a reverse phase column, and expressing the results as 4-epioxytetracycline epimer. Results indicate OXY is well retained at mg kg −1 levels in soil exposed to contaminated pig manure fertilisation. Such compartment could constitute an abiotic reservoir for the systemic and/or for the external contamination of corn.

“…Contamination of compound feeds with antibiotics depends on a number of factors including human error, production practices, and handling procedures in the feed mill. Contamination of nonmedicated feed can also occur during transport to farms and, eventually, at the farm during storage, manipulation, and mixing operations (12,16). However, there are few publications about contamination of feedingstuffs with antibiotics.…”

The paper describes a microbiological method for the detection of antibacterial substances in feedingstuffs. The method allowed detection of the main antibiotic groups, including tetracyclines. In 2013-2014, a total of 171 feed samples were analysed to determine antibacterial substances. Among the analysed samples 84 (49.1%) were suspected to contain tetracyclines. Out of the 84 feeds analysed using chromatography, 28 (33.3%) contained undeclared tetracyclines, which were identified at concentrations ranging from 0.32 mg kg -1 to 48.98 mg kg -1 .
