- A study published in the Proceedings of the National Academy of Sciences warns that large-scale poultry farming is driving the growth of Campylobacter bacteria, a common cause of diarrhoea worldwide.
- Researchers analysed around 2,800 bacterial genomes from 30 countries between 1979 and 2024 and found that Campylobacter strains in poultry have grown roughly 100-fold since 1900.
- The report also flags rising antibiotic resistance, meaning infections could become harder to treat, with people at risk from eating raw or undercooked chicken.
- It matters because it suggests intensive poultry farming practices may be fuelling a public health risk, though thorough cooking kills the bacteria.
What to watch next
- Whether antibiotic resistance in Campylobacter continues to worsen in future studies
- Any steps taken by poultry farms or regulators to control overcrowding and bacterial spread
- Reported infection cases linked to undercooked poultry
