General Description
MQCA (3-methyl-quinoxaline-2-carboxylic acid) is a metabolite of N-(2-hydroxyethyl)-3-methyl-2-quinoxaline-carboxamide-1,4-dioxide (Olaquindox). Olaquindox is a broad spectrum antibiotic that is used in animal feed for growth promotion, to improve feed efficiency and to increase the rate of weight gain. In 1991, the Joint FAO/WHO Expert Committee on Food Additives (JECFA) recommended maximum residue limits (MRLs) of 30 and 5 µg/kg in liver and muscle tissues, respectively. In 1998, the European Commission (EC) banned the use of olaquindox in food animal production together with four other feed additives. In 2005, it was banned for use as a veterinary drug by Chinese government regulatory agencies.
