European Food Safety Authority (EFSA) and European Centre for Disease Prevention and Control (ECDC) have published the annual EU One Health Zoonoses Report.

The main findings are, in 2023, listeriosis cases reached their highest level since 2007, while campylobacteriosis and salmonellosis remained the most frequently reported zoonotic diseases in the EU. Overall, reported cases of zoonotic diseases in humans increased, but foodborne outbreaks saw a slight decline.

The number of reported human cases of listeriosis (2,952) showed a consistent rise over the 2019–2023 period, hitting their highest levels since 2007. This might be linked to Europe’s ageing population — 21.3% of Europeans are now over 65 years old — which, in connection with the growing prevalence of chronic age-related diseases, raises the risk of severe symptoms in older age groups. Contaminated ready-to-eat (RTE) foods, such as cold smoked salmon, meat products and dairy products, are the most common source of infections. The latest data show that the proportion of samples from RTE food categories that exceed food safety contamination limits for Listeria monocytogenes ranged from 0.11% to 0.78%, with the highest level reported for fermented sausages.

Campylobacteriosis and salmonellosis were the most frequently reported zoonotic diseases in humans in the EU. In 2023, 148,181 campylobacteriosis cases were reported, marking an increase from 139,225 in 2022. After campylobacteriosis, salmonellosis was the second most reported gastrointestinal infection in humans, with 77,486 cases, compared to 65,478 cases in 2022.

The report also monitors foodborne outbreaks in the EU, defined as events during which at least two people contract the same illness from the same contaminated food. A total of 5,691 foodborne outbreaks were reported in 2023, registering a slight decrease compared to the previous year. However, the number of human cases, hospitalisations, and deaths increased, with fatalities reaching their highest level in a decade. Salmonella remained the leading cause of foodborne outbreaks, cases, hospitalisations and deaths. The increased use of whole genome sequencing improved the sensitivity of surveillance, enhancing the ability to detect outbreaks in Member States that implemented it.
