Official figures released this week show England’s food‑borne illness numbers climbing sharply , with salmonella cases reaching a ten‑year peak and hospital admissions for food poisoning up 87% since 2020. The UK Health Security Agency (UKHSA) and Food Standards Agency (FSA) say warmer weather and over 50 possible risk factors are under investigation.

Salmonella Hits 10,406 Cases – Highest Since 2014

The UKHSA and FSA reported 10,406 recorded salmonella infections last year, the most in a decade. Professor Paul Wigley of the University of Bristol warned that official counts likely capture only one in six real cases, suggesting the true annual burden could approach 60,000 infections across England and Wales.

Campylobacter Remains Dominant with 69,394 Reported Cases

Campylobacter, linked to poultry and pork, accounted for 69,394 confirmed infections, while experts estimate the actual figure may lie between 500,000 and one million. the discrepancy highlights the difficulty of tracking mild cases that never reach a laboratory.

Hospital Admissions Jump 87% Over Five Years

A Freedom of Information request by kitchen‑equipemnt firm Prestige revealed that patients seeking NHS treatment for serious food‑poisoning symptoms rose from 1,370 in 2020 to 2,567 in 2024 – an 87% increase. The data underscores that while many cases resolve at home, a growing minority require medical care.

Climate Change and 50‑Plus Potential Triggers Under Review

Professor Ian Young,chief scientific adviser for the FSA, said expert panels have identified more than 50 possible contributors, from hotter summers that foster bacterial growth to supply‑chain disruptions after extreme weatehr events. The agencies stress that the number of product recalls has not risen, suggesting production‑line hygiene remains stable.

What Remains Unclear: The True Scale of Under‑Reporting

Prof. Wigley estimates only one in ten campylobacter infections is recorded,leaving a massive gap in surveillance. Additionally, the impact of specific climate variables versus behavioural factors, such as undercooking at barbecues, has yet to be quantified.
