Yes, U.S. poultry processors dip birds into chlorine. It "kills bacteria, controls slime and algae, increases product shelf life [and] eliminates costly hand cleaning labor and materials" in addition to disinfecting "wash down" and "chilling" water, says the USDA's Food Safety and Inspection Service. "Pinners" in the slaughter facility who remove the birds' feathers by hand wash their hands with chlorinated water to "reduce odors and bacterial count" after which the birds are sprayed to "wash all foreign material from the carcass." Meat is similarly disinfected with chlorine, says one industrial paper, especially because conveyer belts are "ideal breeding grounds for bacteria." The FSIS directive also reveals that chlorine gas is used on beef "primals," giblets and "salvage parts" and for "reprocessing contaminated poultry carcasses." Bon appetit.

It has only been three years since the nation's stomach churned when it saw photos of "pink slime" oozing out of processing tubes and bound for U.S. dinner tables and the National School Lunch Program. Looking like human intestines, "lean, finely textured beef" (LFTB) was made from unwanted beef "trim" and treated with puffs of ammonia gas to retard the growth of E. coli. While the company making most of the nation's LFTB, Beef Products Inc. (BPI) shuttered three plants and laid off hundreds of employees two years ago, it is since fighting back and has brought a lawsuit against ABC news. Ag giant Cargill has also announced it is bringing back "pink slime" with two changes--instead of ammonia, E. coli will be killed with citric acid and the meat will be identified as "Finely Textured Beef" on its label.
Nine years ago there was an uproar about Big Meat using gasses like carbon monoxide to keep meat an unnatural red even as it was aging on the shelf. The brown color that meat assumes after a few hours is as harmless as a sliced apple turning brown says the American Meat Institute. Right. "Modified atmosphere packaging" of meat, using assorted gasses, is still a mainstay of meat production and "safe and suitable" in meat production according to the FSIS report. Carbon monoxide is also used to "maintain wholesomeness" in "fresh cuts of case-ready muscle meat and ground meat," says the FSIS directive.
