Seeking to obtain information on the ingredients in LaCroix, Consumer Reports apparently discovered that National Beverage Corp. had failed to obtain a permit sell its products in Massachusetts, which requires the submittal of water-quality tests. Consumer Reports notes, "The situation reveals an unusual quirk of food safety regulations: Federal and state regulations typically treat artificially carbonated waters—including club soda, tonic water, seltzer, and sparkling water—differently than bottled water. (Sparkling mineral water, which is naturally carbonated and contains natural minerals, is regulated like bottled water.) And even in states that have added oversight of those fizzy waters, there's apparently occasional slip-ups in enforcement." The article, originally published June 18, 2019, was updated on June 26 to reflect that National Beverage Corp. announced it had obtained the permit required to sell LaCroix within Massachusetts.
