Most antibiotics in livestock farming are used in aquaculture, but significant amounts are also used in terrestrial livestock species, particularly in poultry and pigs.
Approximately 70% of antibiotics are used for non- therapeutic purposes, i.e. many antibiotics are used in sub- therapeutic doses and over prolonged periods, which leads to the development of genes that confer antimicrobial resistance to animal pathogens. These genes can subsequently be transferred to human pathogens and it is estimated that 75% of recently emerging diseases in humans are of animal origin.
Antimicrobial resistance (AMR) problems are further exacerbated by the fact that antibiotic resistance genes were found in bacteria long before antibiotics were ever used on super-pathogens in farm animals.
AMR is a worldwide problem, which clearly affects both animal and human health, and hence it is truly One Health issue.

The European Agriculture Council has formally approved a draft law on animal diseases that are transmissible among animals and potentially to humans (zoonoses).
The provisions in the law on farm animal health visits stipulate that professional animal owners are to receive regular animal health visits from a veterinarian for disease prevention, detection and biosecurity. This new piece of legislation aims to merge and update existing scattered directives and regulations into a single and coherent law.
It is announced as an important step forward, since visits by vets are the cornerstone of the ‘prevention is better than cure’ strategy and indispensable for the prevention and early detection of known and emerging transmissible diseases. The role of the veterinarian in achieving this is defined and highlighted. The veterinary profession also has an active part to play in raising awareness of animal health and of One Health, or the interaction between animal health, animal welfare and public health.

Following the successful eradication of Rinderpest (Cattle plague, see blog), veterinarians, farmers and donors across the World are turning their focus to combat Foot-and-Mouth Disease (FMD) on a global scale. The FAO and the World Organisation for Animal Health (OIE) have developed a detailed strategy for FMD control under the umbrella of their Global Framework for the Progressive Control of Transboundary Animal Diseases (GF-TADs). However, it is clear that only a massive commitment of national and international resources can make FMD eradication possible, as surveillance and monitoring over a long period is required.
FMD is a highly infectious disease caused by a picornavirus, which affects cloven-hoofed animals, in particular cattle, sheep, goats, pigs and deer. Other animals including camelids and elephants can also be affected. The disease is notifiable, which means that the local veterinary services must be notified immediately if FMD is suspected.Although FMD does not pose a direct threat to human health, and is rarely fatal in animals, it can cause reduced milk yield, weight loss and lower fertility.
