I Found Hair Inside Pedigree Biscrok Dog Treat

We found a hair inside the Pedigree Biscrok dog treats that our dog has loved and eaten for years. We usually break the biscuit in half to give it to our dog, and a strand of hair came out of one of the halves. We’ve been buying this product for years, and I never thought we would experience something like this.

What kind of hygienic conditions are these treats being produced in?
