"Citrus fruits, it turns out, are allowed by law to be contaminated with up to 95 parts per million (ppm) of sodium aluminum fluoride, while potatoes are permitted to have up to 22 ppm on the outside skin, and two ppm on the inside flesh. Raisins are allowed to have 55 ppm of the chemical, while romaine lettuce can have up to 40 ppm. But perhaps the worst offender is iceberg lettuce, which is allowed to have a whopping 180 ppm of sodium aluminum fluoride, or 180 times the amount of fluoride typically added to municipal water supplies."
