Antimicrobial resistance

Antimicrobials, such as antibiotics, are substances used to kill microorganisms or to stop them from growing and multiplying. They are commonly used in human and veterinary medicine to treat a wide variety of infectious diseases.

Antimicrobial resistance (AMR) refers to the ability of microorganisms to withstand antimicrobial treatments. The overuse or misuse of antibiotics has been linked to the emergence and spread of microorganisms which are resistant to them, rendering treatment ineffective and posing a serious risk to public health. A well known example of a bacterium that has acquired resistance to multiple antibiotics is Meticillin-resistant Staphylococcus aureus (MRSA).

Resistant bacteria can spread through many routes. When AMR occurs in zoonotic bacteria present in animals and food it can also compromise the effective treatment of infectious diseases in humans.

In the field of food safety, policy makers need to protect consumers from risks related to the food chain and to establish the best control options to reduce such risks. Scientists and risk assessors are examining the factors which may lead to the presence of antimicrobial resistant bacteria in food and animals to provide appropriate scientific advice to decision makers.

October 2022 EFSA publishes a scientific opinion assessing the risk of spread of antimicrobial resistance among poultry, pigs and cattle during transport between farms or to slaughterhouses. The opinion outlines the main risk factors, mitigation measures, and data gaps.

Milestones

  1. 2022

    March

    OECD, ECDC, EFSA and EMA present the briefing note “Antimicrobial Resistance in the EU/EAA – One Health Response” (PDF) to the French presidency of the EU council. It includes data on consumption of antibiotics in humans and food-producing animals, policy options and highlights the importance of cooperation across disciplines, sectors and countries.

  2. 2021

    October

    Experts assess the concentrations of antimicrobials resulting from cross-contamination in feed for food-producing animals that do not lead to the development of resistant bacteria. They also assess the levels of antimicrobials that have a growth promotion or yield increase effect. One scientific opinion describes in detail the methodology used and provides general conclusions and recommendations, and 12 opinions report the result of the assessment performed for 24 substances. A public consultation was carried out on the methodology used for the assessment.

  3. June

    EFSA, EMA and ECDC publish their third joint inter‐agency report on integrated analysis of data on antibiotic consumption and development of antimicrobial resistance in Europe (2016-2018). Experts conclude that use of antibiotics has decreased and is now lower in food-producing animals than in humans.

    EFSA experts assess the role of food producing environments in the emergence and spread of AMR. They identify the main sources of AMR bacteria and genes, although current data do not allow quantification of the specific contribution each of them makes to this global problem.

  4. 2017

    October

    EFSA, the European Medicines Agency (EMA) and the European Centre for Disease Prevention and Control (ECDC) establish a set of indicators to help EU Member States assess their progress in reducing the use of antimicrobials.

  5. January

    Experts from EFSA and EMA review measures taken in the EU to reduce use of antimicrobials in animals and stress that there is no one-size-fits-all solution. Successful strategies follow an integrated, multifaceted approach which takes into account the local livestock production system and involves all relevant stakeholders.

  6. Since 2011

    EFSA and ECDC have been compiling a joint report on AMR in zoonotic bacteria affecting humans, animals and food. This annual report makes an important contribution to work being carried out at European level and supports the European Commission as it develops proposals to fight AMR.

  7. 2009

    November

    EFSA, ECDC, EMA and the European Commission’s Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) publish a joint scientific opinion on AMR focused on infections that can be transmitted to humans from animals and food (i.e. zoonotic diseases).

  8. March

    EFSA assesses the public health significance of meticillin-resistant Staphylococcus aureus (MRSA) in animals and foods. It concludes that livestock-associated MRSA represents only a small proportion of all reported MRSA infections in the EU with significant differences between Member States.

  9. 2008

    April

    EFSA experts examine how food may become a vehicle for transmitting resistant bacteria to humans and make recommendations for preventing and controlling transmission. EFSA publishes further specifications for the harmonised monitoring of AMR in Escherichia coli and enterococci bacteria in animals and foods.

  10. 2007

    EFSA publishes specifications for the harmonised monitoring of antimicrobial resistance in two important zoonotic bacteria – Salmonella and Campylobacter – found in animals and foods.

EFSA's role

 

EFSA provides independent scientific support and advice to risk managers on the risks to human and animal health related to the possible emergence, spread and transfer of AMR in the food chain and in animals. EFSA takes an integrated approach to its work on antimicrobial resistance involving a number of its Scientific Panels and Units as it is a concern for the entire food chain.

In its work, EFSA cooperates closely with other relevant EU agencies such as the European Centre for Disease Prevention and Control (ECDC) and the European Medicines Agency (EMA).

Monitoring and analysis of antimicrobial resistance in the food chain

EFSA monitors and analyses the situation on AMR in food and animals across Europe. The Authority is assisted by the Network for zoonoses monitoring data, a pan-European network of national representatives and international organisations that assist EFSA by gathering and sharing information on zoonotic diseases in their respective countries.

Based on data collected by the EU Member States, EFSA produces in cooperation with ECDC annual European Union Summary Reports on zoonotic infections, food-borne outbreaks and AMR illustrating the evolving situation in Europe. EFSA also publishes baseline survey reports on the prevalence of antimicrobial resistance in the EU in specific animal populations, for instance MRSA in pigs, and provides guidance to national authorities how to carry out their monitoring and reporting activities.

EFSA’s Scientific Panels review the annual reports and make recommendations on prevention and reduction measures.

Risk assessments and recommendations

EFSA’s Scientific Panels assess the risks of antimicrobial resistance and provides scientific advice on control options at the request of risk managers or on its own initiative. This work has included risk assessments by the Panel on Biological Hazards on antimicrobial resistance in the food and feed chain and the public health significance of MRSA in animals and food focusing on the specific type of MRSA found in food-producing animals. The Panel on additives and products or substances used in animal feed assesses the safety of animal feed additives, including the risks related to antibiotic resistance where micro-organisms are involved.

EU framework

To tackle antimicrobial resistance, a holistic, multi-sectorial approach, involving many different sectors (human medicine, veterinary medicine, research, animal husbandry, agriculture, environment, trade and communication) is needed.

In June 2017 the Commission adopted the EU One Health Action Plan against AMR, as requested by the Member States in the Council conclusions of 17 June 2016. It builds on the 2011 action plan, its evaluation, the feedback received on a European Commission Roadmap on AMR and a public consultation.

A number of risk management measures to combat AMR are in place related to the food chain. EU legislation on foodborne zoonotic diseases - animal diseases or infections transmissible between animals and humans - obliges Member States to monitor trends in AMR in zoonoses and other agents that may present a threat to public health.

At international level, countries cooperate through an Intergovernmental Task Force on AMR which reports to the Codex Alimentarius Commission. The EU and United States have also created a transatlantic task force on AMR issues.
