Buried in a N.Y. Times piece on the demand for cage-free eggs is this nugget that Ben found while editing AnimalNet tonight:

"Officials at Notre Dame turned down a request by a campus animal rights group to switch to cage-free eggs after investigating the issue for six months.

The university, which serves 16,000 meals a day in its dining halls, visited both cage and cage-free operations, examining animal welfare, food safety, environmental impact, taste and other issues. Both operations they toured appeared to take equally good care of their chickens, said Jocie Antonelli, nutrition and safety manager.

The university decided that its current source of eggs, which uses a cage system, had the edge in food safety.

“There are pros and cons to each system,” Ms. Antonelli said. “Either way, these are not free-roaming chickens living out in a pasture.”

The story does not explain what constituted the edge in food safety, but the mere mention of food safety – microbial food safety – is encouraging.
