Puzzle 220

Ethoxyquin, a chemical preservative, was originally developed as a rubber stabilizer. It was later refined for use as a preservative in animal feeds. Before the late 1980's there was little Ethoxyquin used in pet foods. After companies started to make high performance feeds they began to use more of this chemical
to extend the shelf life of their products. Shortly after this, some pet owners began to see dramatic changes in their animals. Puppies were dying, deformed or stillborn. One breeders prized studs throat looked like raw hamburger and every time he walked he would leave a trail of blood.
