Asian, African and South American countries have seen a giant upswing in commercial meat production. Often, these animals are given a steady stream of antibiotics along with their feed. After long-term exposure to these drugs, the bacteria learn how to resist the medication.
The study states that 73 percent of all antimicrobials sold go into animals raised for food. This constitutes an overreliance on the antibiotics, which could lead to problems later as the bacteria continue to adapt to new medicines. Even when given antibiotics, animals still carry bacteria in their gut. Those bacteria, especially if resistant to antimicrobials, can spread when the host animal is slaughtered and processed. This can affect other meat products and even get into the water, which may be irrigated with contaminants., often contracted by eating raw or underprepared chicken, affects 1.3 people in the U.S. each year, according to the Centers for Disease Control .
