Constant worldwide structural changes in animal production (including aquaculture) have
crucially contributed to increased health risks for animals and humans. Worldwide, huge
economic losses are caused by OIE List A diseases, "new" or infectious diseases long
believed conquered, antibiotic-resistant and multifactorial diseases. In addition,
such diseases often pose serious trade barriers. Problems due to disease can be reduced
or even eliminated if the entire spectrum of preventative and prophylactic measures
are implemented as part of health programs. This strategy requires the cooperation
of producers, veterinarians, public health authorities, the industry and consumers.
Thanks to their position in the economy, consumers can provide producers with
economic incentives to act. The implementation of animal health programs is
a continual, never-ending process.
