The argument below is from the book "A concise introduction to logic".
The condition under which many food animals are raised are unhealthy for humans. To keep these animals alive, large quantities of drugs must be administered. These drugs remain in the animals' flesh and are passed on to the human who eat it.
In this argument the first statement is the conclusion and other two are the premises.
I am unable to find in what way or in what sense the premises support the conclusion. For me it doesn't seem to be an argument.
How do the premises support the conclusion of this argument?
