Antibiotic resistance: "One of the Greatest Threats to Public Health"

Lance Price

In the United States, there are nine billion food animals produced annually including, 34 million cattle, 108 million hogs, 267 mililon turkeys, and 8.9 billion broilers. In contrast, there is only a human population of about 300 million people. Only a fraction of those people will be treated with antibiotics (for 10 days or so a year), but those nine billion animals will be treated all the time whether they're sick or not.

Combined with overcrowded and unsanitary conditions, feeding healthy animals antibiotics to prevent disease and promote their growth are ideal grounds for evolution of antibiotic-resistant bacteria. These are bacteria that are no longer inhibited or killed by antibiotics at clinically relevant doses and evidence continues to grow that many of these resistant bacteria do eventually make their way to humans (some originated in humans and made their way back).
