Tap water or ice made from tap water may be found in some foods and beverages you may not think to worry about, including ice cream, fruit juices or smoothies diluted with water, frozen sweet beverages, ice pops, fountain drinks, or sodas that don’t come from a sealed bottle. You should also be on the lookout for unpasteurized (raw) milk or dairy products made from unpasteurized milk, such as ice cream or cheese. If you’re not sure, ask.
