Animal health and welfare

As is the case for humans, animal health can be threatened by various viruses, bacteria and parasites. ANSES's expertise offers insights into the complex interactions between pathogens, animals and rearing conditions, while supporting the management of health crises. It therefore contributes to prevention and control of the main animal diseases affecting livestock and wildlife, as well as the zoonoses affecting human health. It also works to improve animal welfare while ensuring the safety of the food chain and the sustainability of the different production sectors.

What are the risks and impacts of diseases transmitted by the tiger mosquito?

The tiger mosquito is now found in 78 départements of mainland France. Its presence increases the risk of an epidemic of dengue fever, chikungunya or Zika. In an expert appraisal published on 13 September 2024, ANSES concluded that there was a fairly high probability of such an epidemic occurring. This could have health, economic and social impacts, particularly on the healthcare and tourism sectors.

Towards the integrated surveillance of antimicrobial resistance

Bacterial resistance to antibiotics is a major health problem for both humans and animals. In France, the use of antibiotics and the distribution of resistant bacteria are covered by several surveillance schemes that do not consistently or sufficiently collaborate with one another. The Surv1Health project, which has just been completed, aimed to identify ways of breaking down silos in the surveillance of antimicrobial resistance and making it more useful as part of the ‘One Health’ approach.

Vector-borne diseases: a concern for cattle health

The common factor linking bluetongue, epizootic haemorrhagic disease, besnoitiosis, etc. is that they are all caused by pathogens transmitted to ruminants by arthropods such as ticks, midges or mosquitoes. ANSES has funded a review of studies carried out in metropolitan France, which highlighted the many gaps in current knowledge about the vectors found on cattle farms and the pathogens they can transmit. Such knowledge is nevertheless essential given current global changes, which are having an impact on vector distribution and therefore on the epidemiology of vector-borne diseases in livestock.

What scientific criteria can be used to develop animal welfare labelling for food products?

Consumers are increasingly concerned about the living conditions of the animals used to produce foodstuffs such as meat, dairy products and eggs. ANSES is publishing guidelines for labelling products of animal origin specifically with respect to farm animal welfare. Implementing this proposal would harmonise current and future labelling systems. One of its main features is that the welfare assessment is based on scientific indicators measured directly on the animals, and not just on their rearing conditions. Another of its distinguishing features is that it takes account not only of the living conditions of the food-producing animals themselves, but also those of their parents.

Five questions on bluetongue

Bluetongue is a viral disease of ruminants, and does not affect humans or food. It is transmitted by biting midges and can cause major economic losses in livestock farming. Vaccination is the most effective means of prevention, but is expensive. Here is a profile of the disease and an overview of the work of ANSES, a leading player in the fight against this virus.

The tiger mosquito

Native to the tropical forests of Southeast Asia, the tiger mosquito (Aedes albopictus) has adapted to many different environments, particularly urban ones, colonising a vast array of containers in which it lays its eggs in small volumes of water. The tiger mosquito is an opportunistic anthropophilic species which bites humans and can transmit viruses such as dengue, chikungunya and Zika. Because of this, it represents a major public health challenge. Below you will find an introduction to a mosquito that we haven’t heard the last from.

Understanding and combating tick-borne pathogens

There are just under 1,000 species of tick in the world, but only a few are vectors of pathogens. Nevertheless, ticks are the vectors that transmit the widest variety of pathogens (bacteria, viruses and parasites) in the world. They are responsible for infectious diseases in humans and animals, and are the main vector of animal pathogens in Europe.

Bees: essential pollinators whose health is under threat

Bees account for 90% of pollinating insects, along with bumblebees, butterflies and flies. For several years now, a phenomenon resulting in the weakening and mortality of bee colonies has been seen around the world. Bee decline would have major consequences for plant diversity and food supply. Diseases, predatory insects, pollen depletion, chemicals... ANSES studies and assesses the stress factors threatening bees, and proposes different scientific and regulatory solutions to protect their health.

Everything you need to know about epizootic haemorrhagic disease

Epizootic haemorrhagic disease (EHD) is a viral disease that was first detected in France in 2023. Its spread is a direct consequence of climate change, which enables the midge vectors of the disease to survive in our regions. Which animals does it affect? What are the symptoms? Is there any treatment? Can this disease be transmitted to humans? All the answers to these questions are in this article.

Q fever, a disease that can be passed from ruminants to humans

Q fever is often misunderstood, even though this disease is widespread throughout the world and was discovered almost a century ago. It can cause reproductive problems in ewes, female goats and cows and be transmitted to humans. Although the disease is generally not serious, it can nevertheless lead to complications, and sometimes takes months or even years to develop after initial infection.

Brucellosis

Brucellosis is a disease caused by bacteria of the genus Brucella . Found worldwide, it can affect humans, with symptoms including fever, pain, headache and/or weakness. It also affects most mammalian species, domestic and wild ruminants in particular. In animals, brucellosis causes abortion, reduced fertility and reduced milk production, which may in turn induce major economic losses. In addition, animals or herds which have not been certified as brucellosis-free cannot circulate freely between countries. Driven by these major economic implications and to the risk to human health, ANSES is actively involved in brucellosis surveillance and control. Here we provide a presentation of the disease, its current status in France, and the role played by ANSES.

ANSES’s work to prevent the spread of avian influenza

Avian influenza can cause high mortality in wild and domestic birds. In addition, under certain conditions the virus can be transmitted to humans. ANSES plays a major role in the fight against the disease by coordinating its diagnosis in animals and by conducting research to improve virus detection, determine the strains in circulation and assess new vaccines for poultry. It also supports the public authorities in assessing the risks of disease introduction ahead of new outbreaks, and in recommending management measures during animal epidemics.
