“…Nitrofuran (NF), mainly including furazolidone (FZD), nitrofurazone (NFZ), nitrofurantoin (NFT), and furaltadone (FTD), are a class of synthetic broad-spectrum antibacterial drugs with a 5-nitro structure that were commonly used in veterinary drugs for the treatment of protozoan and gastrointestinal infections. , These drugs metabolize rapidly within a few hours after ingestion, and the residual metabolites could remain in the body for weeks, possibly even months, as protein-bound compounds. − These NF metabolite compounds have been proven to pose potential risk to human health because of their carcinogenic, teratogenic, and mutagenic potency. , Based on food safety needs, the use of NF drugs was banned by the European Union during the cultivation of animal products. , Since then, many countries have followed the suit, such as the United States, China, and Japan. − However, because of the low price and significant efficacy, NF drugs are still allowed or illegally used as veterinary drugs in some developing countries. , At present, the minimum performance limit (MRPL) of these residual compounds in meat products stipulated by the EU is 1.0 μg/kg. , In this context, it is essential to develop a fast and sensitive detection method for NF metabolite compounds for solving food safety problems.…”
