The impending superbug crisis needs to be addressed from a number of different angles, but eliminating antibiotics for growth promotion and prophylactic purposes in livestock and fish production is perhaps the most pressing priority. As a consumer, you can add pressure on the industry and hasten this change by demanding antibiotic-free meats and animal products, no matter where you shop and eat.
Ideally, buy directly from a local farmer or rancher who raises his animals according to organic standards. Sustainably raised animals are also less likely ( but certainly not definately) to be contaminated with pathogenic bacteria. This goes for pork and chickens and their eggs as well.
You have to chose – You are what you eat.
