New hand-washing requirements and restrictions on touching food with bare hands are among new food service rules adopted by New Jersey as it looks to clamp down on illnesses spread by food. Officials said the new regulations were not prompted by the E. coli infections suffered by 33 New Jerseyans whose illnesses late last year were linked to Taco Bell restaurants. The new rules govern food service at 50,000 food stores, restaurants, banquet facilities, caterers and other establishments. The regulations, announced Monday and effective immediately, include detailed hand-washing requirements for food workers, including specific instructions on how, how long and when to wash and how to dry hands properly. For instance, workers washing their hands will have to rub them together vigorously for at least 10 seconds, paying particular attention to areas underneath fingernails. Bare-hand contact with ready-to-eat foods has been banned.
