美国豁免甲基磺酸的最大残留限量

       据美国联邦公报消息，8月19日美国环保署发布终期条例，在一定条件下豁免甲基磺酸的最大残留限量。

    根据新条例，当甲基磺酸（methane sulfonic acid）作为酸化剂用于动物时，最大残留限量为3.0%（以重量计），作为抗菌农药配方的惰性成分用于公共饮食场所、乳品加工设备以及食品加工设备和器具，且用量不超过5000ppm时，豁免其残留限量。

    本条例自发布之日起生效，征求意见的截止日期为10月19日。

    部分原文报道如下：

    This regulation establishes an exemption from the requirement of a tolerance for residues of methane sulfonic acid （CAS Reg. No.75-75-2） when used as an inert ingredient （acidifying agent） in pesticide formulations applied to animals at a maximum concentration not to exceed 3% by weight and when used as an inert ingredient in antimicrobial pesticide formulations applied to food-contact surfaces in public eating places, dairy-processing equipment, and food-processing equipment and utensils at a concentration not to exceed 5,000 parts per million （ppm）。 Lewis & Harrison, on behalf of BASF Corporation, submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of methane sulfonic acid.
