Question 5

Owl pellets are commonly found around owl roosting sites and are examined in school lessons to detect the skeletal remains of their prey and determine their eating habits.One student questions if the owl pellets are a serious bacterial concern.What is a reasonable and accurate reply?

Accepted Answer

A) Owl pellets would be a serious hygienic concern since they have gone through the bird's intestine and,similar to a human intestine,would be mixed with many gut bacteria 
B) Owl pellets are probably not too serious a problem because bacteria in an owl's intestine are probably not disease agents for humans
