Question

Livestock production in the U.S. today uses nearly 3 times as many antibiotics as are prescribed for all human patients. It is most likely that routine use of antibiotics in animal feed will result in:

A) an effective, long term way to eliminate disease-causing bacteria in the animals and therefore increase food production.

B) The animals developing resistance to the antibiotics.

C) An increased number of antibiotic-resistant bacterial strains

D) the elimination of viral infections and thus increased food production.

E) ever fewer disease-causing bacteria in the environment

Explanation / Answer

The correct answer is C).

The excessive use of antibiotics results in increased number of antibiotic resistant bacterial strains. If antibiotics have been fed to animals over a period of time as mentioned 3 times in the above case, they retain strains of bacteria which has became resistant to antibiotics these resistances can be due to genetic modifications or genetic inheritances. These resistant bacterial strains then proliferate in animals through colonization and finally came in contact with the humans through the farms and slaughterhouses via feces, intestines etc.
