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.

Ruminant fat, gelatine and collagen: precautions required when including them in the feed of farm animals

In Europe, the sharp decrease in cases of transmissible spongiform encephalopathies (TSEs) has led to an easing of the restrictions on the use of products of animal origin in the feed of food-producing species. In the expert appraisal it recently published, ANSES concluded that ruminant fat, gelatine and collagen should only be used in certain conditions, in order to guarantee the absence of any risk of transmitting TSEs.

Colistin combined with nanoparticles: a smaller amount of antibiotic for the same level of efficacy

Scientists from ANSES's Ploufragan-Plouzané-Niort Laboratory took part in a study on the efficacy of colistin-loaded alginate nanoparticles used to treat diarrhoea in piglets. Undertaken in collaboration with teams from University of Lille (BioEcoAgro Cross-Border Joint Research Unit) and CNRS (Institute of Electronics, Microelectronics & Nanotechnology), this study showed that this new formulation, which requires less colistin than conventional treatment, has equal or even greater efficacy.

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.
Brucellosis
12/04/2023

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.

Wildlife, a reservoir of pathogens

Some pathogens are specific to the wild animals that carry them. However, they can be transmitted to humans or domestic animals through contact. ANSES's work, which focuses on both wild and domestic animals, helps improve understanding of how these pathogens jump from one species to another and attempts to combat these transmissions.

Food safety, from farm to fork

Milk, meat, vegetables... any of the food we eat can be a source of contamination. Through the transmission of bacteria, parasites, viruses of animal or plant origin, or chemical contaminants, our food can potentially cause illness or poisoning in humans. Food safety forms part of a global "one health" approach, at the interface of animal, plant and human health. To protect consumers from the risks of food contamination and prevent potential outbreaks, it is essential to take action at all stages of the food chain, "from farm to fork". This is ANSES's role.

Eight questions on animal welfare

The concept of animal welfare is at the crossroads of numerous philosophical, moral, scientific, technological, economic, regulatory and social influences that are sometimes conflicting. The welfare of animals dependent on humans – livestock, pets, animals used for scientific purposes and zoo animals – is playing an increasingly important role in our society. What is animal welfare? Is it enough just to treat an animal well? How is animal welfare objectively measured? Is it possible to redefine animal husbandry in order to improve it? And what is ANSES doing about it? You will find the answers to all these questions in our article.
