Governments around the world have recognized the growing threat that antimicrobial resistance (AMR) has on our ability to treat infections in humans.
Why is this so important for animal health? Many of the same antimicrobials used to treat and prevent infections in human medicine are also used in animals.
Some antimicrobials are more important than others for treating people. Health Canada classifies them into four categories, based on whether:

What drugs fall into these categories? The chart below presents a list of the key drug products that fall into each category:
