NOTE: The U.S. Food and Drug Administration (FDA) issued a final rule on July 3, 2008 prohibiting the extra-label use of cephalosporins (including ceftiofur in swine) in food-producing animals. The agency is issuing this order based on evidence that extra label use of these drugs in food-producing animals will likely cause an adverse event in humans and, as such, presents a risk to the public health. Public comment regarding the rule will be accepted until September 2, 2008 and the rule will go into effect on October 1, 2008.
This action would add cephalosporin antimicrobials to the list of drugs prohibited for extra-label use by the FDA. Given the recent approval of Baytril® for use in swine, it is important to remember that it too is among another class of drugs, fluoroquinolones, that are also prohibited for extra-label use in food animals.
Under the Animal Medicinal Drug Use Clarification Act (AMDUCA) drugs on this list may not be used under any circumstances in an extra-label manner even by a veterinarian.
Sorry that this review is not related to the intended use of this product... However, if it works nearly as well on cows as it does for eliminating thrush / white line disease in horses, it is an excellent product! I tried everything to eliminate my horse's chronic thrush / WLD. This is the only solution I have found for him in year-round damp, northern FL, where he is out to pasture 24/7. Tomorrow helps keep his hoof ailments in check! The tubes are so handy for applying the medication - less waste, less on your hands / clothes. Great stuff.
