Keep your hive contamination free

My Question is bees live in an open environment travel in a wide areas. I’m thinking all honey are contaminated with some types pesticide or GMOs. Question 1. Do anyone test their honey for contamination? If so how do you test for it’.?! Question 2. How do you keep your hives contamination free?

Those are great questions:
#1 No.
#2 I don’t even try.
