The United Nations General Assembly passed a declaration aiming to slow down the spread of bacteria that have become resistant to antibiotics. The U.S. is well underway in following the U.N.’s directive. Animal health companies are eliminating the use of antibiotics important to human medicine for the purpose of promoting growth in animals. In many cases, these antibiotics will only be available under a Veterinary Feed Directive, essentially a prescription from a veterinarian, starting the first of the year.
