About a month ago, the Food and Drug Administration (FDA) ruled that antibiotics should not be used in livestock for the purpose of promoting growth. As with most FDA rulings, they do not garner a lot of weight as their decisions are non-binding. In a surprise however, many livestock farmers who were polled about the ruling have stated that they would comply with the ruling. For years, we have seen the outcome of use of antibiotics in livestock as the numbers of antibiotic resistant bacteria types and associated infections rise. Now that the FDA has taken this intervening step, we now have to consider finding a balance in this process. Antibiotics still have a place in the raising of livestock as a means to insure that one sick animal does not infect an entire herd. As a preemptive action, antibiotics should still be used and used judiciously to reduce the potentially devastating economic effects of the loss of livestock due to illness.
A few days after the antibiotics ruling, the FDA also asked manufacturers of antibacterial products to conduct additional research to prove that an active ingredient, triclosan is safe for long-term use. Triclosan has been shown in lab testing to have deleterious effects, especially on children. In lab rats, triclosan has been shown to decrease thyroid hormone, affect metabolism and reproduction. These companies have to prove that triclosan, in it’s current formulation will not have these long term effects or will, if not shown have to reformulate their products without triclosan. It is interesting to note, the FDA first ruled on the use of triclosan in 1978, when it was in limited use. As the use of this chemical has expanded. the FDA felt it was in the interest of consumers to call for this review in advance of a potential new ruling on triclosan’s use in 2016.
FDA rulings have very little teeth as far as compliance and enforcement are concerned. I have been saying for a few years now that the role of the FDA needs to be drastically changed in order to better serve the needs of consumers and to insure that rulings truly have the force of law behind them. Without any major changes on the horizon, it will appear that the only way that proper regulation is in place will be via the legislative branch through the passing of new laws that will reduce antibiotic use and if triclosan is shown to be problematic in long-term use, that the chemical be regulated more closely or outright banned for use. Before that, we need to have alternatives, safe alternatives to triclosan so that our antimicrobial products still have usefulness in this era of unprecedented antimicrobial resistance.
