Yes, pink slime is gross stuff. Call me crazy, but I prefer my burgers without added ammonia. But it's not even close to the grossest thing about our meat-production system—far from it.

Here are some highlights:

• Rodents on egg conveyor belts
• Rotting corpses in cages with hens laying eggs for human consumption
• Hens stuck by their heads, legs and wings in cage wires
• Mummified hen carcasses in cages
• Overcrowding of hens in cages that only provide 54-58 square inches [less than 8 inches by eight inches] of living space per hen (well below the national average for egg-laying hens)
• Flies in barns so thick that the investigator had to scrape off his boots after walking down each aisle
• Piles of dead hens on floors of barns
• Dead flies in hens’ feeding troughs
• Barns so dark that workers needed head lamps and flashlights
• Ammonia levels so high that workers often had to wear masks
• Manure and eggs from some barns tested positive for salmonella
• Each worker is tasked with overseeing more than 100,000 animals.
