My kid is eating beggin strips and I am concerned?

a href="http://www.purina.com/begginstrips/" rel="nofollow"http://www.purina.com/begginstrips//a Is this even safe for a human to eat? He gets real fussy when I try to take it away. I really don't want to upset him and I mean the dog eats them and is happy but they certainly dont taste like bacon.
