Perdue Farms, a competitor, said it eliminated the routine use of antibiotics in chicken past year.
The World Health Organisation has urged farmers to stop using antibiotics to promote growth and prevent disease in healthy animals because of the serious risks to human health that result.
"Healthy animals will not receive antibiotics for prevention of a disease diagnosed in other animals of the same herd, of the same farm or the same population in the case of fish", does it.
Where possible, sick animals should be tested to determine the most effective and prudent antibiotic to treat their specific infection.
Asian riseIn some countries, around 80 per cent of total consumption of medically important antibiotics is in the animal sector According to the Scientific American, the United States has moved toward reducing antibiotic use in agriculture, but China and other Asian countries have started using more.
About 80% of antibiotics worldwide are used in animals, something health experts say is contributing to the growing problem of antibiotic resistance, in which common infections no longer respond to the drugs used to treat them. Figures collected via the eMB-Pigs database showed the pig industry cut use by 35% in 2016, with further reductions expected this year, while new targets require a 62% overall reduction between 2015 and 2020.
Antibiotics that are considered to be in the last line of defence for humans should not be used at all it says.
The recommendations are part of new guidelines from the World Health Organization on what constitutes inappropriate use of antibiotics in the food chain, with the aim of tackling one of the main causes of antimicrobial resistance.More news: Call of Duty: WWII's launch brings in $500 million, doubling Infinite Warfare
Dr. Chavonda Jacobs-Young, USDA acting chief scientist, said, "The WHO guidelines are not in alignment with US policy and are not supported by sound science".
"Farmers will play their part and have in the past number of years made significant investment in raising the health status of their animals through the implementation of disease eradication programmes, which reduce the requirement for antibiotics". A new and demanding set of targets for each of the key livestock sectors will ensure momentum continues. "The new guidelines illustrate the degree to which our regulators and large food animal producers are falling short". For example, since 2006, the European Union has banned the use of antibiotics for growth promotion.
"We know some practices in veterinary medicine, as in human medicine, can not continue". "We also believe that all food animal production must meet a high standard of animal welfare".
Farmers in the United Kingdom insisted that the requests were unnecessary and incompatible with British farming.
The organization has issued its first formal guidelines on how such drugs should be used in farms.
"USDA agrees that we need more data to assess progress on antimicrobial use and resistance, and we need to continue to develop alternative therapies for the treatment, control, and prevention of disease in animals".
"The recommendations erroneously conflate disease prevention with growth promotion in animals", Chavonda Jacobs-Young, the U.S. Department of Agriculture's acting chief scientist, said in a statement.
