Overview
Aidara-Kane A et al.. Antimicrob Resist Infect Control 2018 · PMID 29375825 · DOI 10.1186/s13756-017-0294-9
WHO recommends ending antibiotic use for growth promotion and for prevention in healthy animals.
Does the study support the specific claim? Yes · Methodological quality: high
Plain-language summary
Study explained simply
- What did the researchers want to find out?
How should medically important antimicrobials be used in food-producing animals?
- How was the study done?
Summary of WHO guideline developed with GRADE and commissioned systematic reviews
- How many people, animals or samples were studied?
not applicable
- What was actually found?
Recommends reduction in overall use of medically important antimicrobials, complete restriction of use for growth promotion and for disease prevention in healthy animals, and no use of critically important antimicrobials unless susceptibility testing shows they are the only option.
- How large was the observed effect?
Recommends reduction in overall use of medically important antimicrobials, complete restriction of use for growth promotion and for disease prevention in healthy animals, and no use of critically important antimicrobials unless susceptibility testing shows they are the only option.
- What do the results mean in everyday life?
The international health authority agrees that farm antibiotic use is a resistance problem.
- What are the study's limitations?
Recommendations rest partly on low-certainty evidence
- What does it say about Elawady's specific claim?
Supports the resistance concern; does not quantify human harm.
- Do the results apply to Germany and Europe?
EU rules (Reg. 2019/6) largely implement these principles.
- What can explicitly not be concluded from this study?
Not a measure of current use in any country.

- Industrial chicken is raised with routine antibiotics, and antibiotic-resistant bacteria (e.g., ESBL E. coli, MRSA, resistant Campylobacter, mcr-1) spread from poultry to humans via the food chain. – Studies supporting the claim
- Antibiotics were (and are) used in poultry production to make chickens grow faster. – Studies supporting the claim
