Measures to prevent infections, such as biosecurity measures and use of vaccines, are among the most important tools to decrease antibiotic use in the animal sector without decreasing animal health, welfare and productivity. Also, infection prevention diminishes the risk for spread of antibiotic resistant bacteria between animals and between animals and humans.
To have basic routines for prevention and control of infectious diseases at farms, in veterinary practices and in other human – animal interactions is crucial to decrease antibiotic use as well as the risk for spread of antibiotic resistant bacteria. Accurate information about biosecurity measures and data showing the cost-benefit of different measures are important to increase farmers’ motivation to adopt biosecurity measures. Increasing number of reports demonstrate the economic benefit of applying disease prevention measures such as improved heard management, biosecurity and vaccination. These measures can also lead to substantial reduction in antibiotic use. In one study of pig farms, antibiotic use were decreased 52% from birth to slaughter.
Infection prevention efforts are also important to reduce the spread of zoonotic diseases through the food chain. The global burden of foodborne diseases is considerable, and particularly affects persons living in low-income areas. Also antibiotic resistant bacteria can spread via food, and ensuring food safety is an important component of efforts to limit the spread and effects of antibiotic resistance. Food safety has often been low on the political agenda. However, due to the growing evidence on the negative health effects of foodborne diseases, it is likely that food safety issues will receive more attention in the future. Improving food security is highlighted as one of the priority areas of the United Nations “Sustainable Development Goals”, to be achieved in 2030.
Work to improve infection prevention
There are no universal best practices for disease prevention at animal farms, but there are a number of measures that can be taken to improve infection prevention and control and reduce antibiotic use. Set up a program and Interventions provides more information and tools to facilitate the work.
