Quote by Jonathan Safran Foer
There is a glaring reason that the necessary total ban on nontherapeutic use of antibiotics hasn't happened: The factory farm industry, allied with the pharmaceutical industry, has more power than public-health professionals.
Summary
This quote suggests that the lack of a comprehensive ban on the nontherapeutic use of antibiotics, which is deemed necessary in public health, is primarily due to the influential role of the factory farm industry and pharmaceutical companies. These two industries, joined together, wield more power than public health professionals, preventing the implementation of strict regulations. The quote implies that political and economic interests override public health concerns in this context.
