Ice cream and frozen treats without the listed preservatives

48 of the 48 ice cream and frozen treats foods on the list pass this check. A short, fixed list: BHA, BHT, TBHQ, potassium bromate, brominated vegetable oil, propylparaben and azodicarbonamide. Other preservatives, such as citric acid or sorbates, are not counted.

They may still fail one of the other four checks; the strip on each card shows which.
