为便于中国兽药残留标准的改进和相关法规体系的建立提供参考,同时为中国畜产品贸易提供数据参考,保障人们的饮食安全,促进中国畜产品经济的更好发展,本研究首先对中国新国标GB 31650-2019《食品安全国家标准食品中兽药最大残留限量》中规定的猪组织中兽药残留种类和兽药最大残留限量(MRLs)标准进行了简单分析;然后对美国、欧盟、日本和食品法典委员会(CAC)规定的猪组织中兽药残留种类和兽药MRLs标准与中国新国标进行对比,通过对规定兽药总数、中国没有规定而其他标准有规定的兽药种类、其他标准严于中国标准的兽药种类等几项内容的比较,找出差异。结果显示,中国新国标做出了更加详细的补充和修改;从整体上来看,中国规定的猪组织中兽药MRLs标准越来越完善,大部分标准与欧盟、美国、日本和CAC规定标准的差距也越来越小,然而在部分种类兽药MRLs标准的规定方面和这些国家或组织仍有一定的差距。中国需加强与各个发达国家和组织的交流与合作,推进中国的兽药残留标准的发展,加快对动物产品质量安全标准的更新。 相似文献

The harmonization of standards and procedures for establishing tolerances or maximum residue levels (MRLs) for veterinary drug residues in edible animal products is a major goal of the international veterinary drug community. Such harmonization would contribute to easing trade barriers. This paper proposes use of the toxicologically determined acceptable daily intake (ADI) for the drug as the safety standard for reaching conclusions on the acceptability of residues in meat for human consumption. Specifically, the 'equivalence' of different MRLs for the same veterinary drug would be determined by considering whether they are likely to result in dietary residues that exceed another country's ADI for the drug. Two methods of estimating dietary intake are described, and estimates are made for the veterinary drugs albendazole and ivermectin. Based on these estimates, the US and JECFA MRLs for each drug would be considered 'equivalent' for trade purposes. 相似文献

Since the USDA implemented the National Organic Program, the growth of the organic food market has continued to increase, with organic poultry as leading products. Organic livestock husbandry practices focus on living conditions that permit natural behaviors and provide outdoor access, preventive health management with a prohibition of antibiotics or other drugs (although vaccines can be used), and organic feed. Organic feed is raised without synthetic fertilizers and pesticides; pastures to which birds have access must also be organic. Hatcheries are currently not required to be organic, and conventional chicks may be used if they are under organic management by the second day after hatching. Although alternative, slow-growing genotypes are used in organic production in the European Union, conventional genetics are used in the United States. Poultry products, including meat and eggs, must be handled organically. Most synthetic materials are not permitted in organic food production, whereas most natural materials are; however, the National Organic Program National List specifies which materials are allowed. Of particular interest is an impending ban on the use of synthetic methionine in organic poultry diets. Research in the United States has examined alternative strategies, including the use of slow-growing broilers that are less heavily muscled than conventional fast-growing meat birds, but has not shown these birds to have lower methionine requirements. Research has also examined sensory differences between specialty and conventional meat chickens in the United States. Consumer panelists indicated no preference between these products, although trained panelists found some differences in the flavor of thigh meat. More meat quality differences were due to genotype than to outdoor access. Breast meat from slow-growing birds was more tender than that from fast-growing birds. Outdoor access resulted in leaner meat, but only in the case of slow-growing birds. As interest grows in specialty and organic poultry meat products, additional research is needed. 相似文献

文章根据2000-2017年中美兽药产品贸易的进口额和出口额,计算了中美两国兽药产品产业内贸易G-L指数及B指数,分析两国兽药产业内贸易情况。经研究认为,中美兽药产业内贸易整体水平不高,但是呈近年来上升趋势,且中美兽药贸易增加的原因以产业内贸易为主。另外,中美兽药产业的产业内贸易可能是受到市场需求差异、产品差异、规模经济等因素的影响。最后,针对研究结果提出促进中美产业内贸易发展的建议,包括继续充分利用两国资源禀赋的互补性,加大技术引进、技术创新的力度,加强中美兽药产业贸易更进一步向产业内贸易的转化。 相似文献

兽药在畜禽养殖中发挥重要作用,但由于养殖户盲目用药,药物选择和使用不规范,随意搭配药物,造成兽药使用量超出安全剂量规定,不仅严重威胁畜禽和人类健康,还污染土壤、水源和大气环境,因此必须对畜禽养殖中的兽药使用进行科学引导和严格规范。该文对我国目前畜禽养殖业兽药使用的现状进行分析,从兽药生产企业准入门槛和销售流通环节入手,结合兽药法律法规、兽药使用规范、兽药监管体系、兽药检测制度提出改善对策。 相似文献
