Even the existence of direct and easy to understand causal links doesn't prevent corporate disinformation campaigns if there is money involved. Just look at the history of tobacco propaganda. Cato is still feeding the media articles and quotes denying that there are health risks from second hand smoke. If you want to find an industry where antibiotics crate large profit then look at industrial farming.
What percentage of antibiotics used in industrial animal farms are still patented, and what's the profit margin and net profit from those antibiotics at biotech companies?
Altogether, the US meat industry uses 29 million pounds of antibiotics every year. To put that number in perspective, consider that we humans in the United States—in all of our prescription fill-ups and hospital stays combined—use just over 7 million pounds per year. Thus the vast bulk of antibiotics consumed in this country, some 80 percent, goes to factory animal farms.
