Samples of pig blood, intended for ochratoxin A analysis, were collected from pigs of 279 randomly selected herds. The samples were obtained at nine different slaughterhouses from different areas of Sweden. Pigs from 47 herds (16.8% of the total) exhibited ochratoxin A in amounts of greater than or equal to 2 ng of ochratoxin A per ml of blood. One sample each from a single pig per herd identified herds contaminated with ochratoxin A in amounts exceeding three times the detection limit of the method (3 x 2 ng of ochratoxin A per ml of blood = 6 ng of ochratoxin A per ml of blood). There was a good agreement between ochratoxin A concentrations in the blood from different pigs within the same herd (correlation coefficient = 0.80). The ochratoxin A concentration in pig blood was used as an estimate of the ochratoxin A content of the consumed feed. This method showed that feed from grain produced on-farm contained higher concentrations of ochratoxin A than commercial feed preparations. No geographical variation of ochratoxin A occurrence within Sweden was detected.
从279个随机挑选猪群的猪身上采集了用于赭曲霉毒素A分析的猪血样本。这些样本取自瑞典不同地区的9个不同屠宰场。47个猪群（占总数的16.8%）的猪血液中赭曲霉毒素A含量大于或等于每毫升血液2纳克赭曲霉毒素A。每个猪群从一头猪身上采集的一个样本确定了赭曲霉毒素A污染量超过该方法检测限三倍的猪群（每毫升血液3×2纳克赭曲霉毒素A = 每毫升血液6纳克赭曲霉毒素A）。同一猪群中不同猪的血液中赭曲霉毒素A浓度之间存在良好的一致性（相关系数 = 0.80）。猪血中的赭曲霉毒素A浓度被用作所消耗饲料中赭曲霉毒素A含量的估计值。该方法表明，农场生产的谷物饲料中赭曲霉毒素A的浓度高于商业饲料制剂。在瑞典未检测到赭曲霉毒素A出现的地理差异。
