Prevent infection  –  Food animals

Set up a program

The main diseases that drives antibiotic use in the animal sector are common infectious endemic diseases such as mastitis, pneumonia and diarrhea. These diseases also cause decreased productivity. Thus, disease prevention is an important factor both to lower antibiotic use and to increase the productivity of the animal.

There is no universal best practice to prevent diseases in farm animals, as the measures have to be specific to the problems on the individual farm. A possible starting point is to do an analysis of the herd management, biosecurity and health situation of the farm. This will indicate what measures that will be valuable and applicable at the specific farm. In order to evaluate the health status of the heard it is good to establish a disease recording system. Ideally this should be based on both clinical observations within the herd and recording of lesions at slaughter. Data on weight gain, pregnancy results and farrowing rate are also valuable for evaluation of the health status of the herd.

After health status among animals has been improved, changes in how antibiotics are used can be introduced with retained animal health and productivity.


Improved biosecurity and herd management optimization have been shown to increase productivity parameters and decrease disease treatment incidence in farm animals. Despite this, biosecurity measures at farm level can be poorly implemented. Introduction and continous improvement of biosecurity measures is essential for a health oriented farming system.

What is biosecurity?

Biosecurity is the series of management steps taken to prevent the introduction of infectious agents into an animal herd or flock. It usually involves testing incoming animals, and some sort of quarantine or isolation for newly purchased or returning animals (external biosecurity). Biosecurity also includes measures to diminish the spread of an infectious agent that have reached a herd (internal biosecurity or biocontainment).

Prevention of foodborne zoonoses

Food is one of the potential routes of transmission of antibiotic resistance. Both zoonotic bacteria and the normal gut flora of the animal can carry resistance genes, and these bacteria can contaminate the meat during slaughter. Measures to reduce the risk of spreading antibiotic resistance via food are the same as for other food safety issues, and includes the whole food chain such as disease prevention at farm, and appropriate hygiene from farm to fork.

Guidelines on processes and methodology for risk analysis concerning foodborne antibiotic resistance related to non-human use of antimicrobial agents have been developed. These guidelines also provide advice on appropriate risk management activities to reduce such risk.
