Weeks after taking a job as a breeding technician at Eagle Point Farms, an anguished Sharee Santorineos sat down and wrote a three-page whistleblower complaint. I seen pigs that are pregnant beat with steel bars," said her letter to the Illinois Bureau of Animal Health and Welfare. Santorineos knows about raising animals. At a friend's rural Illinois farmhouse, she grows pigs and poultry that they eventually will have slaughtered. Like other worker allegations about animal abuse in Illinois' 900-plus hog confinement facilities, Santorineos' account went nowhere. The state has regularly discounted or dismissed such worker complaints, a Tribune investigation has found. In the Illinois hog confinements that send 12 million pigs to market annually, the bureau did not find a single animal welfare infraction or violation during the past five years. A lack of inspectors - the bureau has just six - contributes to the scant enforcement, while weak Illinois and federal livestock protection laws do little to safeguard animals. In on-the-record interviews, Santorineos and more than a dozen other Illinois swine-confinement workers told the Tribune they witnessed fellow employees whip pigs with metal rods and gouge them with pliers and ballpoint pens to hurry the animals from one stall to the next or onto the trucks that took them to slaughter. They described employees abusing pigs for amusement and encouraging colleagues to take out their frustrations on the animals.
