I don’t see the alternative to inspectors for the US food supply. Your assertion that small businesses do it better is questionable.
As for the local small businesses can do it better what is your question? I already indicated if a small business provides a tainted product they will go out of business. If a large one does then it simply is a dip in profits. Schwans Ice Cream is a good example. So was Pilgrim’s Pride turkey I used as an example. If you think it is questionable support your statement and we can discuss the point.
