Scientific assessment
Mostly true – Correct at its core, but with limitations or minor inaccuracies.
Certainty of evidence: moderate – Further research may still affect the assessment.
1. What was claimed?
(Implicit through bibliography) Poultry farming poses infectious and respiratory risks to humans.
2. What is demonstrably correct?
H7N9 cases in China were linked to wet-market poultry contact (two of four described patients died). In Egypt H5N1 and H9N2 are enzootic in poultry, vaccination-only control failed, and human cases rose (I-CHK-10). Residents within about 1 km of Dutch poultry farms had an increased pneumonia risk (11%).
3. What is wrong or exaggerated?
These are exposure risks from live birds, slaughter and farm air; they are not evidence that eating properly cooked chicken is harmful.
4. What remains unclear?
Causal pathway for pneumonia near farms (particulate matter, endotoxin, microbiota).
5. Which studies support it?
6. Which studies contradict it?
None.
7. What applies to Germany and Europe?
Avian influenza outbreaks in EU poultry are controlled by culling and movement restrictions; human infections in the EU are rare.
8. What is known about Egypt?
Egypt has had a substantial number of human H5N1 cases, mostly linked to backyard poultry; handling and slaughtering live birds at home is a key risk.
9. What practical conclusion is appropriate?
Avoid contact with sick or dead birds; use hygiene when slaughtering poultry at home; buy from controlled sources.
Assessment details
- Rationale for certainty of evidence
Human H7N9 and H5N1 infections from poultry contact are well documented; Dutch spatial data show about 11% higher pneumonia risk near poultry farms. These risks concern contact with live birds and farm emissions, not eating cooked chicken.
- Source quality
Archive bibliography; studies accurately listed, but their relevance to eating chicken is not explained.
- Regional transferability
Highly relevant for Egypt (H5N1 enzootic, backyard poultry, live-bird markets); lower for EU consumers.
- Individual exceptions
Poultry workers, backyard poultry keepers and live-bird market visitors are at higher risk.
- Regional scope of the claim
- depends on production conditions
- Last reviewed
- 25 October 2026 provisional
In plain language
Some studies listed by the archive show that bird flu can pass from live poultry to people, and that people living very close to poultry farms in the Netherlands had slightly more pneumonia. In Egypt, bird flu is common in poultry and has infected people, mostly those who keep or slaughter birds at home. These risks come from contact with live birds, not from eating well-cooked chicken.

Original publication · Scientific details
Study explained simply
- What did the researchers want to find out?
What are the clinical and viral features of human H7N9 infection linked to wet-market poultry?
- How was the study done?
Clinical case series with viral genome characterisation of human and market-poultry isolates
- How many people, animals or samples were studied?
4 patients; 86 birds; Four hospitalised patients; 86 birds sampled
- What was actually found?
All four had contact with live market poultry; two died; the human virus was almost identical to a market chicken virus; 20% of sampled chickens carried H7N9; no infections among 385 contacts.
- How large was the observed effect?
Descriptive
- What do the results mean in everyday life?
Avoid contact with live birds in markets during outbreaks.
- What are the study's limitations?
Four patients
- What does it say about Elawady's specific claim?
Relevant to contact, not eating.
- Do the results apply to Germany and Europe?
Low (no wet markets of this type).
- What can explicitly not be concluded from this study?
Cannot show risk from cooked chicken.

Pneumonia near Dutch poultry farms

Original publication · Scientific details
Study explained simply
- What did the researchers want to find out?
Is living near poultry farms associated with pneumonia and altered upper-airway microbiota?
- How was the study done?
Spatial analysis of GP records plus microbiota analysis in hospitalised CAP patients
- How many people, animals or samples were studied?
92,548; 126; 92,548 GP patients; 126 hospitalised CAP patients
- What was actually found?
About 1 extra pneumonia per 1,000 people per year for each poultry farm within about 1 km (background 9 per 1,000), roughly 11% more; throat-bacteria differences were borderline and not significant after correction for multiple tests.
- How large was the observed effect?
Kernel model; PERMANOVA
- What do the results mean in everyday life?
Farm emissions may affect neighbours.
- What are the study's limitations?
No adjustment for smoking or other confounders in the main model; distance as exposure proxy; small microbiota study without healthy controls; single year.
- What does it say about Elawady's specific claim?
Not about eating chicken.
- Do the results apply to Germany and Europe?
High (EU).
- What can explicitly not be concluded from this study?
Cannot show dietary risk or that farm emissions cause pneumonia.

General scientific assessment
Mostly true Live poultry can transmit bird flu, a real risk especially in Egypt, but this does not make cooked chicken unsafe to eat.
The following areas of food safety are relevant to this statement:
- Veterinary medicines and antibiotics
- Hormonal growth promoters
- Contaminants (heavy metals, PFAS, PCBs, dioxins, nitrate)
- Pathogens (Salmonella, Campylobacter, etc.)
- Animal husbandry and feed
- Controls, imports, recalls, labelling
