Welcome to this resource centre of material that may help you better understand some of the issues involved in the use of antibiotics in animal production in Australia. Our view is that the positive impacts far outweigh the negative. This was confirmed again with a new antibiotic risk assessment of macrolides in the US, published in the Journal of Food Protection (May 3, 2004), a peer reviewed journal. Key findings from a risk assessment of two macrolide antibiotic compounds, tylosin and tilmicosin, have determined that their use does not adversely affect the safety of the food supply. "We found that there is an extremely low risk of a person eating beef, poultry, or pork and acquiring a resistant infection that is untreatable with a human macrolide antibiotic," said lead author H. Scott Hurd D.V.M., Ph.D., Hurd-Health Consulting. The study assessed two bacteria, which are known to have resistance to certain antibiotics, and developed a mathematical equation to determine if using these two macrolide antibiotics could lead to food-borne infections in humans that are difficult to treat. The results of the study, which was conducted by Dr. Hurd and a number of independent medical, food safety, and veterinary experts, show that the risk of acquiring a resistant Campylobacter infection from beef, pork, or poultry that results in a difficult-to-treat food-borne illness is less than one in 10 million. For resistant Enterococci faecium, the chances are even lower – less than one in three billion. “Given these results, and the fact that human macrolide antibiotics are rarely used to treat people who have food-borne infections, macrolides certainly are among the safest for use in food animal production,” said Ronald N. Jones, M.D., The JONES Group/JMI Labs, North Liberty, IA, who was one of the co-authors of the article.
