PORTLAND, Ore. -- Public health officials said a teenager in Multnomah County caught a case of E. coli from a brand of commercial cookie dough as part of a national outbreak.

Nestle voluntarily recalled more than 40 kinds of Toll House refrigerated cookie dough and issued a statement saying that the public shouldn't eat the recalled products, after E. coli cases were reported across the country.

Public health officials said among those who came down with a case of E. coli was a Multnomah County teenager who became sick in early May but has since recovered. The teen told health officials that she tasted the cookie dough while baking -- a practice that has long been warned against by doctors.

Public health officials have reported 65 cases nationwide in 28 states, but no deaths have been reported.

Dr. William Keene of the Oregon Department of Human Services Public Health Division provided some tips on how to deal with the recall:

1. Discard or return any of the recalled Nestlé Toll House items. Do not eat or even taste them.
2. Try to resist the temptation to eat any cookie dough, cake batter or similar product before it is cooked. Raw eggs are always a risky bet, and some other common baking ingredients are safer after they have been cooked.
3. Wash your hands thoroughly with soap and water before and after preparing food, as well as before eating, after using the toilet and after changing diapers.
