There's no sugar-coating it. We're at a critical junction, and we have to get serious about this issue. Tens of millions of people are likely going to die in the coming decades as a result of widespread antibiotic abuses. The presence of mcr-1 may further speed up the prevalence of bacteria impervious to every single antibiotic currently available. There are no quick and easy answers here.
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.
