During the evening of Thursday, June 18, the Colorado Department of Public Health and Environment urged Coloradans not to eat raw Nestle Toll House cookie dough because of possible contamination with E. coli O157:H7.

David Cantor, Founder and Director, Responsible Policies for Animals, Glenside, Pa., writes to say thank you for Nicholas D. Kristof’s plea for food-policy reform (“Lettuce From the Garden, With Worms,” column, June 21). Though factory-style production worsens it, the root problem is animal use.

The Nestlé USA plant at the center of a federal probe into an E. coli outbreak involving cookie dough refused to give inspectors access to pest-control records, environmental-testing programs and other information, according to newly released inspection reports covering the past five years.

I know I sound a bit like a broken record asking yet another company to step up and admit they have a problem, pay the victims’ medical bills and lost wages, and then focus on how the problem happened and how to prevent it from ever happening again.
