The perceived risks of using antibiotics in farm animals are related to the ability of bacteria to develop resistance to antibiotics. Given that pathogenic bacteria are sometimes transferred from animal protein to its consumer, it is prudent to ask whether this creates any risk of compromising the ability of antibiotics to treat human illness. That question has been on scientific and political agendas, and subject to repeated debate, since the 1950s. The argument to eliminate certain uses of these drugs in animals appears persuasive. However, the argument excludes examination of why antibiotics are used on the farm.
Antibiotics are essential tools in disease-management regimen in food animals.
In discussing the need to look at both risks and benefits, it is important to consider the interlinked factors in the food chain. Making a risk decision in one area may result in greater risk in another. Balance viewing the system as a whole and considering all factors is critical for safeguarding public health. Physicians, veterinarians, government regulators, producers and antibiotics manufacturers enjoy many points of agreement. All have a stake in prolonging the usefulness of today s medicines.
