Commission Implementing Decision

of 12 November 2013

on the monitoring and reporting of antimicrobial resistance in zoonotic and commensal bacteria

(notified under document C(2013) 7145)

(Text with EEA relevance)

(2013/652/EU)

THE EUROPEAN COMMISSION,

Having regard to the Treaty on the Functioning of the European Union,

Having regard to Directive 2003/99/EC of the European Parliament and of the Council of 17 November 2003 on the monitoring of zoonoses and zoonotic agents, amending Council Decision 90/424/EEC and repealing Council Directive 92/117/EEC1, and in particular Article 7(3) and the fourth subparagraph of Article 9(1) thereof,

Whereas:

(1)

Directive 2003/99/EC provides that Member States are to ensure that monitoring provides comparable data on the occurrence of antimicrobial resistance (AMR) in zoonotic agents and, in so far they present a threat to public health, other agents.

(2)

Directive 2003/99/EC also provides that Member States are to assess the trends and sources of AMR in their territory and transmit to the Commission every year a report covering data collected in accordance with that Directive.

(3)
In the Communication of 15 November 2011 from the Commission to the European Parliament and the Council — Action Plan against the rising threats from Antimicrobial Resistance2, the Commission proposes to put in place a five-year action plan to fight against AMR based on 12 key actions, including strengthened surveillance systems on AMR.
(4)
In the Council Conclusions of 22 June 2012 on the impact of antimicrobial resistance in the human health sector and in the veterinary sector — a One Health Perspective3, that Institution calls upon the Commission to follow up on its Communication of 15 November 2011 through concrete initiatives to implement the 12 actions set out in that Communication, and to collaborate closely with the European Centre for Disease Prevention and Control (ECDC), the European Food Safety Authority (EFSA) and the European Medicines Agency (EMA) in strengthening the assessment and evaluation of the occurrence of AMR in humans, in animals and in food in the Union.
(5)
During its plenary sitting of 11 December 2012, the Parliament adopted a Report on the Microbial Challenge — Rising threats from Antimicrobial Resistance4. In that Report, the Parliament welcomes the Commission’s five-year action plan on tackling AMR and considers that the measures recommended in it need to be implemented as soon as possible. The Parliament, in particular, calls on the Commission and the Member States to seek greater cooperation and coordination on the early detection, alert and coordinated response procedures regarding pathogenic antimicrobial resistant bacteria in humans, animals, fish and foodstuffs in order to continuously monitor the extent and growth of AMR.
(6)
Under its Joint FAO/WHO Food Standards Programme, the Codex Alimentarius Commission adopted, during its 34th session in Geneva, the Guidelines for the Risk Analysis of Foodborne Antimicrobial Resistance5 which highlight AMR as a major global public health concern and a food safety issue. The use of antimicrobial agents in food-producing animals and crops is a potentially important risk factor for the selection and dissemination of AMR microorganisms and determinants from animals and food crops to humans via the consumption of food.
(7)

Those Codex Guidelines conclude, inter alia, that surveillance programmes on the prevalence of foodborne AMR provide information that is useful for all parts of the AMR risk analysis process. The methodology of surveillance programmes should be internationally harmonised as far as possible. The use of standardised and validated antimicrobial susceptibility testing methods and harmonised interpretive criteria are essential to ensure that data are comparable.

(8)
The Terrestrial Animal Health Code of the World Animal Health Organisation (OIE)6 in its Chapter 6.7 on ‘Harmonisation of National AMR Surveillance and Monitoring programmes’, underlines the need for the surveillance and monitoring of AMR in order to assess and determine the trends and sources of AMR in bacteria, to detect the emergence of new AMR mechanisms, to provide the data necessary for conducting risk analyses that are relevant to animal and human health, to provide a basis for policy recommendations for animal and human health and to provide information for evaluating antimicrobial prescribing practices and for prudent use recommendations.
(9)
On 9 July 2008, the EFSA adopted a Scientific Opinion on Foodborne antimicrobial resistance as a biological hazard7. On 28 October 2009, the ECDC, the EFSA, the EMA and the Commission’s Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) published a joint scientific opinion on antimicrobial resistance focused on infections transmitted to humans from animals and food (zoonoses)8. On 5 March 2009, the EFSA adopted a scientific opinion on the assessment of the public health significance of meticillin resistant Staphylococcus aureus (MRSA)9. On 7 July 2011, the EFSA adopted a scientific opinion on the public health risks of bacterial strains producing extended-spectrum β-lactamases (ESBL) and/or AmpC β-lactamases (AmpC) in food and food-producing animals10. On 3 October 2011, the EFSA adopted a technical report on EFSA approaches to risk assessment in the area of antimicrobial resistance, with an emphasis on commensal microorganisms11. The main conclusion of all those opinions and reports is that, in view of the increasing public health concern regarding AMR, the use of harmonised methods and epidemiological cut-off values is necessary to ensure the comparability of data over time at Member State level, and also to facilitate the comparison of the occurrence of AMR between Member States.
(10)
On 14 June 2012, the EFSA published a scientific report on technical specifications on the harmonised monitoring and reporting of antimicrobial resistance in Salmonella, Campylobacter and indicator commensal Escherichia coli and Enterococcus spp. bacteria transmitted through food12. On 5 October 2012, the EFSA published a scientific report on technical specifications on the harmonised monitoring and reporting of antimicrobial resistance in methicillin-resistant Staphylococcus aureus (MRSA) in food-producing animals and food13. Those scientific reports recommend detailed rules for harmonised monitoring and reporting on the prevalence of resistant microorganisms in food-producing animals and food, in particular as regards the microorganisms to be included, the origin of the isolates of the microorganisms, the number of isolates to be tested, the antimicrobial susceptibility tests to be used, the specific monitoring of MRSA and ESBL- or AmpC-producing bacteria and the collection and reporting of the data. The involvement of the ECDC in this work will ensure the comparison between the data of the food-producing animals and food sector and the data of the human sector.
(11)

In accordance with the findings of those reports and opinions, when defining the combinations of bacterial species, food-producing animal species and food products to be included in the harmonised monitoring and reporting of AMR, it is important to prioritise the most relevant from a public health perspective. In order to minimise the burden, the monitoring should be derived as much as possible from biological samples or isolates collected in the framework of national control programmes that have already been established.

(12)
Regulation (EC) No 2160/2003 of the European Parliament and of the Council14 provides that Member States are to establish national control programmes which are to include sampling for the testing of Salmonella spp. at different stages of the food chain. Commission Regulation (EC) No 2073/200515 lays down the microbiological criteria for certain microorganisms and the rules to be complied with by food business operators. In particular the competent authority is to ensure that food businesses operators comply with the rules and criteria laid down in that Regulation in accordance with Regulation (EC) No 882/2004 of the European Parliament and of the Council16. The monitoring of AMR in Salmonella spp. should be focused on isolates obtained from the national control programmes and from the testing and verification of compliance set up by the competent authority in accordance with Article 1 of Regulation (EC) No 2073/2005.
(13)
Commission Decision 2007/407/EC17 lays down detailed rules for monitoring AMR to be carried out by Member States, covering Salmonella spp. in fowl, turkeys and slaughter pigs for the period from 2007 to 2012. Such harmonised monitoring should be continued to follow the evolution of trends and be extended to AMR in other pathogens and commensals in line with the increasing public health concern on the role of these microorganisms in the overall risk of AMR referred to in scientific opinions. Monitoring and reporting in accordance to Article 7 and 9 of Directive 2003/99/EC should therefore be in compliance with provisions and technical requirements on the harmonised monitoring and reporting of AMR which takes into account the recommendations set out in the EFSA reports.
(14)

For the sake of clarity of Union legislation, Decision 2007/407/EC should be repealed.

(15)

In order to allow Member States to organise themselves and to facilitate the planning of the monitoring and reporting provided for in this Decision, it should apply from 1 January 2014.

(16)

The measures provided for in this Decision are in accordance with the opinion of the Standing Committee on the Food Chain and Animal Health,

      carcases of bovines under one year of age where the production of meat of those bovines in the F17United Kingdom is more than 10 000 tonnes slaughtered per year sampled for testing and verification of compliance, in accordance with point 2.1.3 of Chapter 2 of Annex I to Regulation (EC) No 2073/2005.

  2. (b)

    C. jejuni isolates from caecal samples gathered at slaughter from broilers and from fattening turkeys where the production of turkey meat in the F18United Kingdom is more than 10 000 tonnes slaughtered per year.

  3. (c)

    Indicator commensal E. coli isolates from:

    1. (i)

      caecal samples gathered at slaughter from broilers and from fattening turkeys where the production of turkey meat in the F18United Kingdom is more than 10 000 tonnes slaughtered per year;

    2. (ii)

      caecal samples gathered at slaughter from fattening pigs and bovines under one year of age where the production of meat of those bovines in the F18United Kingdom is more than 10 000 tonnes slaughtered per year.

  5. (e)

    Where F19the appropriate authority decides to test C. coli in accordance with Article 2(3)(a), isolates from:

    1. (i)

      caecal samples gathered at slaughter from broilers;

    2. (ii)

      caecal samples gathered at slaughter from fattening pigs.

Isolates obtained by the F23appropriate authority from an origin other than those referred to in points (a) to (f), may be tested for AMR by the competent authority on a voluntary basis and kept separately when reported in accordance with point 2 of Part B of the Annex. However, when carrying out such testing for AMR, the specific technical requirements of points 3, 4 and 5 shall apply.

2.Sampling frequency, size and design

2.1.Sampling frequency

F24The appropriate authority must carry out every two years the sampling, the collection and the antimicrobial susceptibility testing provided for in Article 2 to 4 of each combination of bacterial species and type of sample of animal populations or food categories listed in point 1 of this Part and the specific monitoring of ESBL- or AmpC- or carbapenemase-producing Salmonella spp. and E. coli in accordance with point 4 of this Part in accordance with the following rotation system:

  1. (a)

    In the years 2014, 2016, 2018 and 2020 for laying hens, broilers and fresh meat thereof, and fattening turkeys. However, the specific monitoring of ESBL- or AmpC- or carbapenemase-producing indicator commensal E. coli in accordance with point 4.1 shall not be mandatory in the year 2014;

  2. (b)

    In the years 2015, 2017 and 2019, for pigs, bovines under one year of age, pig meat and bovine meat.

2.2.Sample size

F25The appropriate authority must test 170 isolates for antimicrobial susceptibility testing for each combination of bacterial species and type of sample of animal population or food category listed in point 1(a), (b), (c), (e) and (f). However, F26if there is a production of less than 100 000 tonnes of poultry meat slaughtered per year and less than 100 000 tonnes of pig meat slaughtered per year18 F27in the United Kingdom, F28its shall test 85 isolates instead of 170 isolates for each corresponding specific combination.

F29If, in any given year, a higher number of isolates for some of the combinations of bacterial species and type of sample of animal population or food category listed in point 1(a), (b), (c), (e) and (f) is available, all isolates or a representative random selection equal to or greater than the number of isolates required in accordance with the first paragraph, shall be included in the antimicrobial susceptibility testing.

F29If, due to a low bacterial prevalence or low number of epidemiological units, in any given year, the number of isolates required in accordance with the first paragraph for some of the combinations of bacterial species and type of sample of animal population or food category listed in point 1(a), (b), (c), (e) and (f), cannot be achieved, all available isolates at the end of the monitoring period shall be included in the antimicrobial susceptibility testing.

For the specific monitoring of ESBL- or AmpC- or carbapenemase-producing indicator commensal E. coli set out in point 4.1, F30the appropriate authority must analyse 300 samples of each of the animal population and food category, listed in point 1(d). However, F31if there is a production of less than 100 000 tonnes of poultry meat slaughtered per year, less than 100 000 tonnes of pig meat slaughtered per year and less than 50 000 tonnes bovine meat slaughtered per year19 F32in the United Kingdom the F30the appropriate authority must analyse 150 samples instead of 300 samples for each corresponding specific combination.

2.3.Sampling design

Isolates which are tested for antimicrobial susceptibility as provided for in Article 2 shall be obtained from monitoring programmes, based on randomised sampling design. The bacterial isolates referred to in Article 2 must originate from randomly selected epidemiological units or randomly selected within the slaughterhouses. Where diseased animals are sampled, the result of the antimicrobial susceptibility testing shall be kept separately when reported in accordance with point 2 of Part B.

The competent authority shall ensure the randomisation of the sampling scheme and its correct implementation.

In the case of sampling at slaughterhouses as provided for in point 1 of Part A, sampling shall be performed at slaughterhouses processing at least 60 % of the specific domestic animal population in the F33United Kingdom, starting with the slaughterhouses of largest throughput.

Not more than one isolate per bacterial species from the same epidemiological unit per year shall be included in the monitoring provided for this Decision. The epidemiological unit for laying hens, broilers, and fattening turkeys shall be the flock. For fattening pigs and bovines under one year of age, the epidemiological unit shall be the holding.

2.3.1.Representative sampling of samples at slaughter

The random sampling plan shall be stratified per slaughterhouse by allocating the number of samples from domestically produced animals collected per slaughterhouse proportionally to the annual throughput of the slaughterhouse.

The collected samples at slaughter shall be evenly distributed over each month of the year to enable the different seasons to be covered.

Only one representative sample of caecal content per epidemiological unit, derived either from a unique carcass or from a number of carcasses, shall be gathered to account for clustering. The sampling shall otherwise be based on a random selection regarding sampling days each month and which batches are to be sampled on a selected sampling day.

The number of biological samples to be collected in accordance with point 1(a), (b), (c), (e) and (f) of Part A shall be determined in order to achieve the required number of isolates by accounting for the prevalence of the bacteria species monitored.

2.3.2.Collection of representative Salmonella spp. isolates collected in the framework of the F34... control programmes for Salmonella spp. in relevant animal populations and in the framework of Regulation (EC) No 2073/2005

Antimicrobial susceptibility testing shall be carried out for no more than one isolate per Salmonella serovar from the same epidemiological unit per year.

Where the number of Salmonella isolates yearly available per animal population in the F35United Kingdom is higher than the number of isolates required in accordance with point 2.2, a random selection of at least 170 or 85 isolates shall be performed from the collection of yearly available isolates in the F35United Kingdom, in a way that ensures geographical representativeness and an even distribution of the date of sampling over the year. Conversely, in the case of a low prevalence, all the Salmonella isolates available shall be tested for susceptibility.

2.3.3.Collection of samples at retail

F36The appropriate authority must collect at retail random samples of fresh meat of broilers, pig meat and bovine meat without pre-selecting samples based on the origin of the food.

3.Antimicrobials for susceptibility testing, epidemiological cut-off values and concentration ranges to be used for antimicrobial susceptibility testing of the isolates

F37The appropriate Minister must test the antimicrobials and interpret the results using the epidemiological cut-off values and the concentration ranges that are set out in Tables 1, 2 and 3, to determine the susceptibility of Salmonella spp., C. coli, C. jejuni, indicator commensal E. coli, E. faecalis and E. faecium.

Dilution methods shall be performed according to the methods described by the European Committee on Antimicrobial Susceptibility Testing (EUCAST) and the Clinical and Laboratory Standards Institute (CLSI), accepted as the international reference method (ISO standard 20776-1:2006).

4.1.Method for detection of ESBL- or AmpC- or carbapenemase-producing E. coli in broilers, fattening turkeys, fattening pigs, bovines under one year of age and fresh meat of broilers, pig meat and bovine meat

For the purpose of estimating the proportion of samples containing ESBL- or AmpC- or carbapenemase-producing E. coli amongst the caecal samples collected from broilers, fattening turkeys, fattening pigs, bovines under one year of age, fresh meat of broilers, pig meat and bovine meat in accordance with point 1(d) of this Part, the following method shall apply.

For the detection of ESBL- or AmpC-producing E. coli the method shall start by a pre-enrichment step, followed by inoculation on McConkey agar containing a third generation cephalosporin in a selective concentration according to the most recent version of the detailed protocol for standardisation of the European Union Reference Laboratory for Antimicrobial Resistance31. The microbial species E. coli shall be identified using an appropriated method.

The F38appropriate authority may decide, based on the epidemiological circumstances, to test in parallel an additional selective plate that inhibits for the growth of AmpC-producing E. coli to facilitate the specific detection of ESBL-producing E. coli. When using this possibility, the results of the additional selective plate that inhibits for growth of AmpC-producing E. coli shall be kept separately when reported in accordance with point 2 of Part B.

F39The appropriate authority may decide to detect for carbapenemase-producing micro-organisms by using selective pre-enrichment and subsequent selective plating on carbapenem-containing media, according to the most recent version of the detailed protocol for standardisation of the European Union Reference Laboratory for AMR32.

One presumptive ESBL- or AmpC- or carbapenemase-producing E. coli isolate obtained from each positive caecal sample and meat sample shall be tested on the first panel of antimicrobials in accordance with Table 1 and further submitted to extended susceptibility testing as set out in point 4.2 if they are resistant to cefotaxime or ceftazidime or meropenem based on the interpretative criteria (epidemiological cut-off values) listed in Table 1.

4.2.Method for further characterisation and classification of Salmonella spp. and E. coli isolates showing resistance to third-generation cephalosporins or meropenem

All presumptive ESBL- or AmpC- or carbapenemase-producing E. coli isolates identified through the selective plating described in point 4.1 as well as all those randomly selected isolates of Salmonella spp. and E. coli that after testing with the first panel of antimicrobials in accordance with Table 1, are resistant to cefotaxime or ceftazidime or meropenem, shall be further tested with a second panel of antimicrobial substances in accordance with Table 4. This panel includes cefoxitin, cefepime and clavulanate synergy test in combination with cefotaxime and ceftazidime for detection of ESBL and AmpC production. In addition the second panel also contains imipenem, meropenem and ertapenem to phenotypically verify the presumptive carbapenemase-producers.

4.3.Quantitative method to assess the proportion of ESBL- or AmpC-producing E. coli

F40The appropriate authority may characterise the proportion of ESBL- or AmpC-producing E. coli within the whole E. coli population.

That shall be done by enumerating ESBL- or AmpC-producing E. coli and total E. coli present in a sample using dilution methods and subsequent plating onto selective media and non-selective media, according to the most recent version of the detailed protocol of the European Union Reference Laboratory for Antimicrobial Resistance38.

5.Quality control and storage of the isolates

The laboratories designated by the competent authority to perform the antimicrobial susceptibility testing of the isolates included in the F41... monitoring programme, shall be involved in a quality assurance system including proficiency test set up F42at national level, in identification, typing and susceptibility testing of the bacteria targeted by the F41... monitoring of AMR.

Isolates shall be stored by the national reference laboratories for AMR at a temperature of – 80 °C for a minimum period of five years. Other methods of storage may alternatively be used provided that they ensure viability and absence of changes in strain properties.
