The International Organization for Animal Health (OIE) warned about the risk of incorrect use of antibiotics that can generate a growth of resistant bacteria in animals. The OIE announced that this will be one of his fights in 2012.

The OIE’s General Director Bernard Vallat, said that a hundred countries in the world do not have an adequate regulatory framework to use the the antibiotics in animals wich, in medium term, knocked his use.

The head of the OIE indicated that there is some controversy about the use of preventive antibiotics or using them to promote the growth of animals. 

In this sense, Vallat underlined the decision taken ten years ago by the European Union to ban the use of antibiotics to promote animal growth, an "avant-garde political decision that no other country has followed."
