Epizootic haemorrhagic disease is a viral disease that was first detected in Europe in late 2022. Since then it has affected several cattle herds in Italy and Spain. ANSES helped identify and monitor the spread of the virus, which is transmitted by biting midges.

After more than five years, the One Health European Joint Programme (EJP) will soon be coming to an end. Coordinated by ANSES, it has helped put the "One Health" concept into practice with a view to improving knowledge of zoonotic diseases, food safety, antimicrobial resistance and emerging diseases.

For two years, 20 partners from 13 European countries worked together to study SARS‑CoV‑2 and coronaviruses under the COVRIN project. It aimed to gain a better understanding of the factors behind the emergence and spread of the virus responsible for COVID-19, in order to strengthen preparedness for any new coronavirus. ANSES was closely involved in studying the risks of the virus jumping from animals to humans and the possibility of transmission from the environment.

Nematodes are parasitic worms, some species of which cause major crop losses. To prevent their spread, it is important to disinfect organic waste – plants, soil and sludge – and water that have been in contact with these pests before discarding or reusing them. Scientists from ANSES's Plant Health Laboratory have assessed the effectiveness of various disinfection methods enabling this waste to be recovered and reused as part of the circular economy.

A vaccine to combat African swine fever could be produced based on research carried out by ANSES’s Ploufragan-Plouzané-Niort Laboratory. The initial results obtained are promising and are paving the way for an effective means of combating this disease, which is responsible for high mortality rates in pigs and wild boar in several countries in Europe, Asia and the Caribbean.

In late December, a sick cat in the Deux-Sèvres département tested positive for the highly pathogenic avian influenza virus H5N1. ANSES was actively involved in the investigation of this case, which led to a nearby duck farm being identified as the source of the cat's contamination. The increase in such viral transfers from birds to mammals in different countries calls for vigilance, as they could facilitate the possible transfer to humans.

ANSES's Sophia Antipolis Laboratory has participated in a vast genetic analysis of strains of Coxiella burnetii, the bacterium responsible for Q fever, a disease that can be transmitted to humans. This collaboration between animal and human disease specialists, on which a paper was published in late 2022, is the first step in a One Health project on this zoonosis.

Forty-two research projects have been selected by ANSES under the 2022 PNR EST call for proposals. They will receive a total of €7.5 million in funding. This research will provide new knowledge on environmental risks to human health, in the general population or at work, as well as on risks to ecosystems.

An international research team has provided valuable new information about what drives the global spread of genes responsible for antimicrobial resistance (AMR) in bacteria. The collaborative study, led by researchers at the Quadram Institute and University of East Anglia, brought together experts from France, Canada, Germany and the UK and will provide new information to combat the global challenge of AMR.

Based on experiments conducted with several generations of fish, an ANSES team explored the effects of glyphosate and glyphosate-based herbicides on the health of rainbow trout. This research showed that whether used pure or in herbicides, glyphosate could have effects on multiple generations of this species.
