Abstract

Ochratoxin A (OTA) is a mycotoxin produced by several moulds of Aspergillus and Penicillium genera on many agricultural commodities used for feed production. It is primarily a nephrotoxic substance, but it can also cause immunosuppression in pigs and increase their susceptibility to infections. Porcine mycotoxic nephropathy (PMN) is a chronic poisoning associated with OTA exposure. The aim of this paper was to evaluate the content of OTA in pig kidneys which were examined during the regular monitoring of the safety and quality of food of animal origin in the Czech Republic during the years 2012–2021. Results revealed no differences between the monitored years or age categories and no differences between the year seasons, which could have an influence on the storage conditions and thus feed contamination by moulds. The values found in this study are low and similar to those assessed in several studies performed in other European countries and do not exceed the limits set in their legislation, which means these organs do not pose a risk for consumers and do not indicate PMN in monitored pigs. Czech Republic as well as EU legislation do not regulate OTA levels in the food of animal origin yet.

2012-2021年捷克共和国屠宰猪肾脏中赭曲霉毒素A的调查

赭曲霉毒素A (OTA)是一种霉菌毒素，由许多用于饲料生产的农产品上的曲霉和青霉属的几种霉菌产生。它主要是一种肾毒性物质，但它也可以引起猪的免疫抑制并增加它们对感染的易感性。猪真菌毒性肾病(PMN)是一种与OTA暴露相关的慢性中毒。本文的目的是评估2012-2021年在捷克共和国对动物源性食品的安全和质量进行定期监测期间所检测的猪肾脏中OTA的含量。结果显示，监测年份和年龄类别之间没有差异，季节之间也没有差异，这可能会影响储存条件，从而影响霉菌对饲料的污染。本研究中发现的数值较低，与在其他欧洲国家进行的几项研究中评估的数值相似，并且不超过其立法规定的限值，这意味着这些器官不会对消费者构成风险，也不表明受监测猪中存在PMN。捷克共和国以及欧盟立法尚未规定动物源性食品中的OTA水平。

期刊介绍： ACTA VETERINARIA BRNO is a scientific journal of the University of Veterinary and Pharmaceutical Sciences in Brno, Czech Republic. The scientific journal Acta Veterinaria Brno is dedicated to the publication of original research findings and clinical observations in veterinary and biomedical sciences. Original scientific research articles reporting new and substantial contribution to veterinary science and original methods that have not been submitted for publication elsewhere are considered for publication. A written statement to this effect should accompany the manuscript, along with approval for publication by the author´s head of department. The authors bear full responsibility for the contents of their contribution. Book reviews are published, too.
