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.

Disorders on two cattle farms highly unlikely to be due to wind turbines

Farmers from two cattle farms located near a wind farm in Loire-Atlantique have reported various problems with their animals, including a reduction in milk yield and quality, behavioural problems, and an increase in mortality. ANSES stresses that these particular situations require support measures. However, it has concluded that the disorders encountered are most likely unrelated to the presence of the wind turbines. The Agency recommends establishing a suitable comprehensive diagnostic protocol, in order to be able to act promptly in the event of disorders occurring in other farms close to wind turbines.

How to better prevent risks of ingestion of metal fragments by cows

How to better prevent risks of ingestion of metal fragments by cows

Foreign bodies, particularly metal objects, are sometimes accidentally mixed with cattle feed. Ingestion of metal objects can cause damage to internal organs, which can lead to death in the worst cases. Following a request from the association Robin des Bois, ANSES has just published an expert appraisal report to determine the extent of the problem. This report recommends preventive measures to reduce the risk of metal fragment ingestion by cows and suggests that magnets can be administered as an effective method for avoiding injury. Based on data collected in slaughterhouses, during autopsies and on farms, as well as data in the scientific literature, the ANSES working group estimated that in France at least 7 to 20% of cattle are reported to ingest metal foreign bodies. With a cattle population of over 10 million, this estimate provides an idea of the extent of the problem. The presence of foreign bodies in the stomachs of cows is linked to on-farm activities and has highly variable consequences on their health and welfare. In a small number of cases, the ingestion of foreign bodies can cause pain and severe injury. Each year, approximately 30,000 carcasses have to be totally or partially excluded from consumption due to injury caused by ingestion. The foreign bodies and associated injury also cause the death of approximately 29,000 cattle per year on farms. Taken together, these figures account for approximately 0.6% of the French cattle population. Metal objects are the foreign bodies most commonly found in cow stomachs The foreign bodies most commonly found in the stomachs of cows are wires of a few centimetres in length, followed by nails. Objects from activities around the farm are the most likely origin, such as metal components of old tyres used for securing tarpaulins over fodder or silage, bits of fencing broken off when cutting hedges, and waste from building sites. “ All types of livestock farming are affected, whether indoors or outdoors, but counter-intuitively, cows living indoors seem to be more exposed than those grazing outdoors ,” says Charlotte Dunoyer, head of the Unit for the assessment of risks related to animal health, nutrition and welfare. Using mechanised methods to bring fodder in from outside tends to “concentrate metal fragments” in the distributed feed, which does not happen when animals spend more time grazing outdoors. For example, pieces of fencing that have fallen off may be picked up along with the cut grass, and wire from old tyres may fall into the silage .” Best practices to reduce exposure of cows to metal fragments The first step to avoid injury from ingestion of foreign bodies is to act at the source. Experts have issued recommendations to avoid the presence of metal fragments in the cows’ environment. Recommendations include avoiding the use of old tyres to secure tarpaulins over fodder and installing electromagnets on farming equipment used for feeding to attract ferromagnetic objects. Particular attention should also be paid to the maintenance of fences and hedges, as well as building sites around cattle farms, to ensure than no metal fragments are left behind. Magnets to prevent serious injury To prevent the occurrence of serious injury, cattle farmers quite often use magnets. Magnets of a few centimetres in length are placed in the cow's stomach via oral administration. By attracting and trapping metal fragments, the magnets stop them migrating and causing injury to fragile organs, such as the heart or diaphragm. These devices have been proven to be effective. For example, studies on dairy farms in Quebec have shown that animals which have a magnet inside them are half as likely to be diagnosed with a disorder caused by the presence of foreign bodies as animals without a magnet. Magnet administration poses an extremely low risk to animals’ welfare as literature data indicate that trauma following oral administration of a magnet is rare. In terms of public and animal health, “ The risk of the magnet dissolving appears to be negligible over the lifetime of the cow ,” says Nibangue Lare, who coordinated the study. “ However, the working group considered the worst-case scenario. Even if the magnet degraded within a year, the constituents of its components would not pose a health issue for animals or for humans consuming animal products .” Experts recommend the administration of a magnet at the first suggestive signs to avoid the development of serious symptoms, and also depending on the animals’ risk of ingesting metal objects. In particular, the use of a magnet may be considered if other animals in the herd have already been affected by the ingestion of foreign bodies or if the farm is located in a high-risk area, such as former conflict zones or military grounds. Limiting the risks associated with the ingestion of foreign bodies therefore relies on preventing the risk of ingestion in the first place and then limiting its effects.

Bulk selling: recommendations and products to be excluded

How can distributors guarantee the safety of products sold to consumers in bulk? Can all products be sold this way? With bulk selling becoming increasingly popular, driven by social demand as well as by the legislator through the French AGEC Act, ANSES has been asked by the Directorate General for fair Trading, Consumer Affairs and Fraud Control (DGCCRF) to give its opinion regarding products that may not be sold in this way for public health reasons. To continue to effectively protect consumer health, it is important for distributors to apply appropriate procedures to bulk selling.

A memorandum of understanding in animal health and zoonoses

ANSES and the Friedrich-Loeffler-Institut (FLI), the German Federal Research Institute for Animal Health, have signed a memorandum of understanding to develop their scientific and technical partnership in the fields of animal health, welfare and zoonoses according to a "One Health" approach. Both organisations' scientific teams are already taking part in numerous national and European joint research projects, first and foremost Horizon 2020, the European Commission's programme for research and innovation. As reference laboratories at national, European and international level, they work together on the surveillance, detection and control of many infectious animal diseases such as African swine fever, avian influenza and foot-and-mouth disease, as well as various issues related to wildlife. This agreement will strengthen this cooperation, enabling exchanges of technical knowledge and know-how, and the sharing of cutting-edge technologies for increasingly effective scientific studies. The agreement was signed by Thomas Mettenleiter, President of the FLI, and Roger Genet, Director General of ANSES, during the latter's visit to the FLI to attend the symposium on " One Health – Research for Human, Animal and Environmental Health " organised by the FLI to celebrate its 111th anniversary.

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.

Avian influenza in six questions

Avian influenza is a highly contagious viral infection occurring in wild and domestic birds. Wild bird migration periods and movements have an impact on the level of risk of influenza virus transmission from wildlife to poultry farms. Liable to cause extremely high animal mortality and therefore major economic losses, some avian influenza viruses can be transmitted to humans under certain conditions. Here we present the profile of a highly contagious disease and describe the work of ANSES, a key player in preventing the spread of high-pathogenicity avian influenza viruses.
