最近,在市场监督总局组织的食品安全监督抽查中,发现25批食用油,油及其制品,蜂产品和食用农产品不合格,23批涉及农药的食品和兽药超标,包括检查。禁用五氯酚钠,地西泮,孔雀石绿,呋喃唑酮代谢物,氯霉素等药物。

2019年5月,国家市场和暴露管理局公布了20批不合格的食品样本。其中,不合格食用农产品数量最多,共8批次。共有7批不合格样本涉及农药和兽药残留。涉及的主要问题是氟苯尼考,恩诺沙星,土霉素和替米考星。长期食用含有过量药物残留的食物可能对人体健康有一定影响。

国家市场监督局的一些抽样数据表明,过量的农药和兽药残留已成为不合格食品检测的重要原因。为此,一些业内人士指出,食品安全是否得到保障,食品企业应该是自我认定的,必须让严格的制度体系扎根。企业必须有严格的食品安全标准,严格的质量控制体系,严格的售后服务体系,严格的内部控制制度和严格的问责制度。

一般而言,作物和动物使用杀虫剂和兽药来治疗疾病和治疗昆虫,从而形成残留物。关键取决于剩余量是否超过国家食品安全标准。目前,我国农业兽药残留限值是通过科学实验和风险评估获得的,并设定了100倍的安全阈值,只要在标准范围内,就是安全的。但是,一旦标准超标,一些农业兽药及其在自然环境中的降解产物可能残留在环境中或作物上,造成农药污染和环境污染。为了解决农业和兽药中的农药残留问题,它与相关标准的制定和检测仪器的使用密不可分。

In 2014, the Ministry of Agriculture and the National Health and Family Planning Commission jointly issued《食品安全国家标准食品中农药最大残留限量》, which stipulated 3,650 limit indicators for 387 pesticides in 284 foods. The residue limits set by the standard cover 12 categories of vegetables, fruits, grains, oils and fats, sugars, beverages, seasonings, nuts, edible fungi, mammalian meat, eggs, poultry and meat. Crop or product. In 2018, China issued 9 national food safety standards such as《食品安全国家标准 食品中百草枯等43种农药最大残留限量》, which stipulated 302 maximum residue limits for 43 pesticides such as paraquat in food, which are suitable for foods related to limited quantities and used in conjunction with《食品安全国家标准 食品中农药最大残留限量》.

In April 2019, the Ministry of Agriculture and Rural Affairs issued《2019年动物及动物产品兽药残留监控计划》, which regulates the detection of related veterinary drugs. Among them, 13 kinds of amantadine, tetracycline, nitroimidazole and its metabolites, florfenicol and metabolite penicillin G, penicillin V, amoxicillin, carbenicillin, etc. are specified in animal foods. Preparation of β-lactam drugs, sulfonamides, quinolones and residues of tetracycline, oxytetracycline, chlortetracycline and doxycycline in milk, and determination of residual amount of liquid or tandem mass spectrometry.

According to statistics, as of 2017, China has formulated more than 6,000 pesticide and veterinary drug residue standards, covering basically the varieties of pesticides and veterinary drugs commonly used in China and the main food and agricultural products. At the same time, China is still actively promoting the revision and revision of relevant standards. It is planned to reach 10,000 pesticide and veterinary drug residue limit indicators by 2020, which is basically in line with the International Codex Alimentarius standards. The development of these testing methods has pointed out the direction for the smooth progress of agricultural and veterinary drug testing, and promoted the expansion of the food testing market.

xx随着环境科学的发展和人类对生活质量认识的提高,农药和兽药的毒性和残留量将越来越受到关注,成为衡量环境质量和食品安全的重要指标。未来,农药和兽药的检测将越来越普遍,相关检测仪器也将在食品和动物兽药检测市场承担更大的责任。
