I was in California recently. While there, I visited a McDonald's for a cup of coffee and a snack wrap. On my tray was a label that read, "WARNING: Chemicals known to cause cancer or birth defects or other reproductive harm may be present in foods or beverages sold or served here. Cooked potatoes that have been browned such as French fries, hash browns and baked potatoes, contain acrylamide, a chemical known to cause cancer. Other foods sold here, such as hamburger buns, biscuits and coffee also contain acrylamide."
