SCIENTIFIC REPORT OF EFSA AND ECDC
The European Union Summary Report on antimicrobial resistance in zoonotic
and indicator bacteria from humans, animals and food in 20121

ABSTRACT
The antimicrobial resistance data among zoonotic and indicator bacteria in 2012, submitted by 26 European Union
Member States, were jointly analysed by the EFSA and the ECDC. Resistance in zoonotic Salmonella and
Campylobacter isolates from humans, animals and food and resistance in indicator Escherichia coli, as well as data on
methicillin-resistant Staphylococcus aureus, in animals and food were addressed. Resistance in human isolates was
mainly interpreted using clinical breakpoints, while microbiological resistance in animal and food isolates was assessed
using epidemiological cut-off values. Resistance was commonly found in isolates from humans, animals and food,
although marked disparities in resistance were frequently observed between Member States. In Salmonella from
humans, high resistance levels were recorded to ampicillin, sulfonamides and tetracyclines, while resistance to third-
generation cephalosporins and fluoroquinolones remained low. In Salmonella and Escherichia coli isolates from fowl,
pigs, cattle and meat thereof, microbiological resistance to ampicillin, tetracyclines and sulfonamides was commonly
detected, while microbiological resistance to third-generation cephalosporins was generally low. High to very high
microbiological resistance to (fluoro)quinolones was observed in Salmonella isolates from turkeys, fowl and broiler
meat. In Campylobacter from humans, resistance to ampicillin, ciprofloxacin, nalidixic acid and tetracyclines was high,
while resistance to erythromycin was low to moderate. High to extremely high microbiological resistance to
ciprofloxacin, nalidixic acid and tetracyclines was observed in Campylobacter isolates from fowl, broiler meat, pigs and
cattle, whereas much lower levels were observed for erythromycin and gentamicin. Increasing trends for ciprofloxacin
resistance was observed in Campylobacter isolates from humans, broilers and/or pigs in several Member States. Multi-
resistance and co-resistance to critically important antimicrobials in both human and animal isolates were presented,
and for the first time, multi-resistance patterns in Salmonella serovars. Very few isolates from animals were co-resistant
to critically important antimicrobials. A minority of isolates from animals belonging to a few Salmonella serovars
(notably Kentucky and Infantis) were resistant to high levels of ciprofloxacin.

Scientific support & advice
EFSA and ECDC provide independent scientific support and
advice to risk managers and decision makers on the
possible emergence, spread and transfer of antimicrobial
resistance, EFSA collects data on AMR in food-producing
animals, while ECDC collects data on AMR in humans.
Integrated approach
EFSA and ECDC monitor AMR in animals and humans,
using data reported by Member States. The two agencies
cooperate with the European Medicines Agency to analyse
the relationship between antimicrobial use and the
emergence of resistance in food-producing animals and in
humans.

Building successful feed additive dossiers
Consider strategic options - additive groups
1.  Technological: Act on feed & feedingstuffs, e.g.
preservatives, anti-oxidants, emulsifiers,stabilisers, thickeners,
gelling agents, binders, anti-radionucleotides, anticakers,
acidifiers, silage additives, denaturants, mycotoxin de-
activators
2.  Sensory: Add colour to feed/animals or flavour to feeds
3.  Nutritional: Vitamins, pro-vitamins, trace elements, amino
acids, urea
4.  Zootechnical: a. Improve feed digestibility, b. gut flora
equilibrium, c. the environment, or d. “other“ (performance
enhancers, animal welfare, food quality ….)
5.  Coccidiostats & Histomonostats
17

Planning & data audit
ü  Who, what, why, where, when, which, how?
ü  Do we need/want a feed additive approval? If yes, why?
ü  Which category/functional group/s & why?
ü  What do current guidelines/guidance require?
ü  What data are available & do they meet current standards?
ü  What data must be generated?
ü  Time & cost of data generation?
ü  What problems will arise & how do we solve them?
ü  Can we protect our investment?
ü  Iterate until project strategy & plan is clear

Building a successful feed additive dossier
Being a pioneer….
25

Best practices – learning from experience
ü  Start at the beginning – if possible
ü  Collect all relevant & current
EURL/EU/EFSA documents
ü  Focus on key EFSA documents (e.g. sensory guidance for
botanicals)
ü  Check (& challenge?) product positioning & claims with the
client/marketing department
ü  PLAN the dossier – problems, solutions, budgets, & time to
market
26

Do’s
ü  If in doubt, consult the EU Commission &/or EFSA by
e-mail/telecon
ü  Follow EU guidelines to the letter (!) (Reg 429/2008)
ü  Follow relevant EFSA guidance/s to the letter (!), BUT è
ü  Check legal loopholes for opportunities to reduce costs/time (read the
small print in Reg. 429/2008)
ü  Be ruthless with studies that are not EFSA-compliant
ü  Use standard templates for efficacy & tolerance study protocols &
reports
ü  Monitor all studies – visit & communicate with study directors & barn
crews
ü  Check all study raw data & statistics!
ü  Blood samples (& tissues?) in all tolerance studies! (store spare sets?)

28

Don’ts
x  Assume that commercial trials from 1985 will meet current
EFSA standards
x  Run studies without an EFSA-compliant, written protocol
x  Finalise reports without a careful review against EFSA
requirements
x  Submit a dossier without double-checking both e-copies &
paper copies against each other
x  Assume that EURL/EFSA/EU guidance/guidelines will be the
same as for the last dossier submitted, hence
è do not:
x  Copy & paste from the previous dossier to the current dossier
(e.g. species extension) without checking & updating to fit new
EURL/EFSA/EU requirements
29

EFSA Evaluations
GUILTY UNTIL PROVEN INNOCENT
30

EFSA FEEDAP evaluations
EFSA feed additive dossier validation process
²  Informal/formal letter of receipt
²  EFSA completeness check (30 working days)
²  EFSA MiP – Missing Information Parts
²  EFSA validation letter è Clock Zero (6 months evaluation)
²  EFSA circulates dossier to EURL, EU & Member States
²  EFSA requests confirmation that the Public Summary does not
contain confidential information
²  EFSA publishes the Public Summary of the dossier
²  All this will be managed by the EFSA Applications Help Desk
31

EFSA FEEDAP evaluations
EFSA working groups (WG) & plenary meetings
²  Dossier evaluation is mainly undertaken by WG of independent experts –
listed on EFSA web page – not all are FEEDAP panel members
²  EFSA Sins!
²  WGs supported by EFSA FEEDAP scientific officers (Secretariat)
²  Plenary meetings consist of 21 EFSA FEEDAP scientific panel members
– also listed on EFSA web page
²  EFSA opinion is first drafted by WG, then discussed & adopted at EFSA
plenary meetings
²  EFSA plenary may request reworking of WG draft or raise additional
questions for the applicant (!)
²  Hence dossier usually appears at least twice on EFSA FEEDAP agenda
32

EFSA FEEDAP Evaluations
EFSA SIns – Supplementary Information requests
²  = “Clock-Stop”
²  30 working days to reply or
²  Applicant requests time extension/s
²  In theory only 1 EFSA clock-stop (SIn) with all questions from WG
²  In practice, several SIns are more common è
²  (Depends on applicant’s answers & EFSA plenary)
33

EFSA FEEDAP Evaluations
Best practices, must do’s, recipes for success:
ü  Answer all EFSA questions to the letter
ü  Be realistic about time frames & request time
extension/s as necessary
ü  Stick to sound technical arguments & avoid anecdotal data
ü  EFSA want DATA not fairy tales!
ü  Use legal arguments if necessary (Reg. 429/2008!)
ü  Be prepared to yield on less important points (e.g. minimum
effective dose)
ü  Generate essential additional data (DTW!)
ü  Keep EFSA secretariat informed by e-mail

A few botanical examples
44

Non-antibiotic feed additives – e.g. zootechnical
“botanicals”
•  Pioneer feed additives, post-AGP ban
•  Plant-derived, well-researched, & deliver consistent performance
•  Patent protection
•  Innovative delivery to target gut sites
•  Proven quality, purity, stability & guaranteed batch uniformity
•  Safe for animals, consumers, users, & the environment
•  EU/EFSA-approved (2 products in piglets, 1 product in broilers)
•  Under evaluation (≈6 dossiers - 3 broiler, 2 piglet, 1 pig)
•  Several regulatory failures – withdrawn, insufficient safety & efficacy data
•  Many listed as feed “flavours”, but EFSA tough stance on safety – e.g.
botanical residues of toxicological concern
