ISSUE FOCUS FEED & ADDITIVE MAGAZINE April 2023 53 substantial, and efforts to reduce mycotoxin contamination are important for both economic and public health reasons. Mycotoxin surveillance is essential for animal health, to reduce economic loss and to ensure feed quality. Mycotoxin surveillance tools such as screening methods can determine which batches are contaminated above regulated levels, helping feed producers manage feed additives and binders to improve the final product. The need to comply with international mycotoxin regulations for feed and to protect livestock from mycotoxin exposure has necessitated a multi-mycotoxin approach to feed testing. Randox Food Diagnostics Ltd. have developed immunoassay-based Biochip Array Technology (BAT) for the accurate and specific detection of all regulated mycotoxins in a single run. BAT is designed as a mycotoxin detection array and is presented in three formats i.e., Myco 6, Myco 7 and Myco 9 detecting six (6), seven (7) and nine (9) mycotoxins, respectively. The Biochip is a ceramic tile on which antibodies, for each of the mycotoxins, are inter-spaced and spotted on predetermined positions [Discrete Test Regions (DTRs)] on the surface. DTRs enable the accurate identification of the different mycotoxins based on spatial location of each antibody spot. Randox mycotoxin arrays are capable of accurately detecting all regulated mycotoxins i.e., aflatoxins B1,2; G1,2 (AFB), ochratoxin A (OTA), deoxynivalenol (DON), zearalenone (ZEA), fumonisin B1,2,3 (FBs), T2/HT-2 toxin and diacetoxyscirpenol (DAS). In the area of multi-mycotoxin determination in feed, LC-MS/MS is the only other platform capable of simultaneous and quantitative detection. However, this method is expensive in terms of capital, analysis, and maintenance costs. The performance and proficiency of the Myco 7 Array was successfully validated against a multi-mycotoxin LC-MS/MS method for the accurate detection of up to 7 mycotoxins (Plotan et al., 2016). The Myco 7 Array showed a correlation with LC-MS/MS of 100%, 97%, 100%, Test Menu Ochratoxin A Diacetoxyscirpenol T2/HT2 Toxins Zearalenone Deoxynivalenol Fumonisins Aflatoxin B1 Aflatoxin GI Paxilline Our mycotoxin arrays allow simultaneous detection of up to 9 main groups of mycotoxins from a single sample. info@randoxfood.com randoxfood.com Mycotoxin Arrays Validated in accordance with Commission Decision 2002/657/EC and Commission Regulation (EU) No 519/2014.
