抗菌素耐药性
抗菌素耐药性是对全球人类和动物健康的主要威胁,且越来越令人担忧。它还影响食品安全、粮食安全,以及数百万农户的经济福利。
食品在抗菌素耐药性的发展和传播中起着重要的作用。存在于农业生产系统和食物链中的抗菌素耐药性微生物是每个人潜在的暴露途径。农业生产中良好的卫生操作,是实现食品安全的基础,也是解决抗菌素耐药性的关键。
食品法典在抗菌素耐药性中的作用
食品中的微生物(细菌、寄生虫、病毒和真菌)是潜在的食品安全危害。在食品动物中使用抗菌素(可杀死微生物或阻止其生长的药剂)与食物链中耐药性微生物的出现之间的关系是一个令人关切的问题,已成为众多国家和国际磋商的主题。
在食品动物(包括水产养殖)、园艺或人类中使用抗菌药,对人类抗菌素耐药性微生物的影响,不同的微生物和不同的地区其程度不同。
当人类摄入食品中的抗菌素耐药性微生物时,某些种类的微生物可能会致病。这些和其他种类的微生物还可能成为其他微生物(包括人类病原体)的可转移抗性决定因素的来源。
在认识到需要更广泛和多学科的应对措施来应对抗菌素耐药性的情况下,2006年,食典委成立了第一个抗菌素耐药性工作组,以制定以下方面的科学指导:如何评估和管理食品和饲料(包括水产养殖)中存在以及通过食品和饲料传播的耐药微生物对人类健康造成的风险。为了应对全球越来越关注抗菌素耐药性对公共卫生的严重威胁,最近成立了第二个工作组,将会制定科学指导,以便协调一致地管理全食物链的抗菌素耐药性。
关于兽药及其残留物、食品卫生、动物饲料的其他食品法典文本,通过在食物链中防止抗菌素耐药性的发展和尽量减少抗菌素耐药性的传播,也有助于解决抗菌素耐药性。

WAAW/ ACT project countries amplify the call to “Educate. Advocate. Act now!”
World Antimicrobial Awareness Week (WAAW) is taking place this week, 18–24 November, in order to raise awareness globally not only about the threats posed by the spread of antimicrobial resistance (AMR), but of the ways in which we can collectively tackle the problem.
AMR occurs when bacteria, viruses, fungi and parasites no longer respond to antimicrobial agents, such as antibiotics. As a result, antimicrobial drugs become ineffective and infections become difficult or impossible to treat, increasing the risk of disease spread, [...]

WAAW/ Meet the coordinator of the ACT project in Latin America and the Caribbean region
María de los Angeles Gatica is the regional coordinator for the Action to support implementation of Codex AMR texts (ACT) project, which helps countries contain foodborne antimicrobial resistance (AMR). She is one of the youngest project leaders across FAO. We spoke to her about her role and about what has motivated her to help the ACT project to its impressive successes so far.
Can you tell us about your personal background?
I grew up in a rural community on the outskirts of [...]

WAAW/ ACT project is helping the Plurinational State of Bolivia tackle the threat of foodborne AMR
The FAO-implemented and Republic of Korea-funded Action to support implementation of Codex AMR texts (ACT) project is being carried out in six countries, of which one is the Plurinational State of Bolivia. Here, the Project has made great progress in helping the national authorities improve governance of the threat of antimicrobial resistance (AMR) and has supported training to improve surveillance and monitoring of foodborne AMR.
Carolina Tejerina is a protagonist in these activities, and we spoke with her to find out [...]

ACT and FF3 projects meet in Cambodia to share experiences and plan together
The Joint ACT/FF3 meeting took place in Siem Reap, Cambodia, from November 4–8. The “Action to Support Implementation of Codex AMR Texts (ACT)” project, funded by the Republic of Korea, and the FAO Fleming Fund 3 (FF3) global initiative, funded by the United Kingdom’s Fleming Fund, came together for their first joint meeting to share experiences and challenges, foster mutual learning, and plan collaboratively for the year ahead.
Cambodia was highlighted as a model country due to its active involvement in [...]

ACT/ New videos now out!
Three videos have been produced that describe the FAO-implemented and Republic of Korea-funded Action to support implementation of Codex AMR texts (ACT) project and demonstrate some of the successes of the project in the Plurinational State of Bolivia.
The first video provides an overview of the Project, describing the four key areas in which improvement will help drive the fight against foodborne antimicrobial resistance. Those four project components promote improved awareness, monitoring and surveillance, governance, and good practices. In the video, [...]
