About $40,000 worth of eggs were taken from a trailer belonging to Pete and Gerry’s Organics, police said. U.S. wholesale egg prices are at a record high.

Police say they are investigating the theft of 100,000 eggs from a Pennsylvania supplier. Egg prices have surged due to avian flu and holiday demand.

The theft of the eggs, which the authorities said were worth $40,000, comes as grocery shoppers across the country are facing empty shelves and higher prices for eggs.
