Description Semicarbazide (SM) is a metabolite of the nitrofurane Nitrofurazone (5-nitro-2- furaldehyde-semicarbazone), used as indicator to detect the use of nitrofurazone in food-producing animals due to their carcinogenic properties the use of nitrofurans is prohibited within the EU in animal breeding (Commission Regulation 37/2010) . to harmonise the detection of semicarbazide a Minimum Required Performance Limit (MRPL) of 1 μg/kg is set within the EU (Commission Decision 2003/181).
