Film aims to expose dangers in U.S. food industry

Maryland farmer Carole Morison let cameras in to show chickens collapsing and dying before they are put on the market because, she said, of fast weight gain caused in part by antibiotics in the feed. Morison said she lost her contract with Perdue.

The film says U.S. food corporations now widely use industrial techniques linked to growing problems like obesity, diabetes, salmonella, toxic strains of common E. coli bacteria and environmental pollution.

"Confined animal agriculture is so unsustainable in so many ways. It depends on using antibiotics in the feed that lead to antibiotic-resistant diseases. It produces more pollution than any other industry," Pollan said.

"It costs treasury, costs the public health system," he said. "The film vividly shows it costs the people who do the work and of course it is brutal to the animal."

Barbara Kowalcyk, whose 2-year-old son Kevin died from an infection of E. coli, appears in the film trying to persuade Congress to pass "Kevin's law," which would give the U.S. Department of Agriculture the power to shut down plants that produce contaminated meats. It has not passed.

Consumers can effect change, the film says, pointing to Stonyfield Farm's Gary Hirshberg, who now offers his line of organic products at giant chain Wal-Mart due to demand.

"You vote for what you eat by what you buy at the supermarket," Pollan said.
