Mycotoxins are toxic molecules produced by multiple fungal species, including Aspergillus and Fusarium. Fungal infection of crops can result in mycotoxins entering the animal human food supply. Enzyme-linked immunosorbent assays other immunological have been developed to detect foods. To calibrate response those methods, reference materials with known amounts homogeneously dispersed often utilized, where mycotoxin concentrations determined using high-performance liquid chromatography coupled absorbance or fluorescence detection mass spectrometry methods. Therefore, it is important that analytical methods provide accurate precise quantitation mycotoxins. The must also contain quantities mycotoxin. evaluate accuracy precision quantitative results from laboratories were completed each year for several years on ground corn check samples containing levels Results aflatoxin-containing presented this article.

This case report investigated the outbreak of aflatoxicosis in a dairy herd Pakistan, which resulted 30 abortions 40 confirmed (75%) pregnant cows period 35 days and 18.8% depression farm average milk production for entire herd. The analysis concentrate feed total mixed ration (TMR), using enzyme-linked immunosorbent assay (ELISA) procedures from two different local laboratories, indicated concentrations 60 μg/kg dry matter (DM) aflatoxin B1 (AFB1) 100 DM aflatoxins (AFs: sum B1, B2, G1 G2). Subsequently, confirmatory with more sensitive validated multi-metabolite liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was performed. detected concentration AFs TMR 166 ± 3.5 (AFB1:134, AFB2:17.4 AFM1:14.9 DM). (55% DM) as source contamination, presenting >29 times higher than EU-maximum limit value (5.68 Additionally, multi-mycotoxin evidenced co-occurrence 81 other toxic potentially fungal metabolites fed TMR. After replacing contaminated feedstuffs same formulation but new charge ingredients, abortion episodes ceased, increased significantly. In conclusion, data this suggest that may be associated pregnancy losses cattle depression. From public health perspective, also indicate need careful examination animal Pakistan. Since high AFB1 considering literature-reported transfer rates (1-6%) toxin to AFM1 (carcinogen humans) milk, produced during is expected AFM1, raises concerns.
