Everything in Vero Beach was Eaten - Paperback

A transport jet left the Miami Airport carrying experimental food to a cattle farm in Nebraska to check the actual effects on living subjects. Designed to jolt bovines' metabolic systems into overdrive, the designers believed that cows on this diet would grow faster and larger.
Caught in a nasty lightning storm over Vero Beach, one of the plane's cargo doors opened. Large bales of feed tumbled out into the squall and disintegrated in the powerful wind. The small clear pellets contained within the bales swirled to the ground as a more dangerous rain. Thousands of pellets glistened across the fields surrounding the city. The smell of them had attracted a genus of carnivorous animals prevalent on the coast of Florida, and they ate every last nugget. This transformed them into hungry giants hunting the inhabitants of Vero Beach down as if these civilized humans had become cattle themselves.
