78% of candy brands tested positive for elevated levels of arsenic: Three Musketeers, Snickers, Skittles, Nerds, Kit Kats and Jolly Ranchers.

Multiple independent news sources report on a Florida Department of Health investigation conducted in early 2026 that tested 46 candy products from 10 companies for heavy metals, including arsenic. The findings consistently indicate that approximately 60-80% of these candies contained elevated levels of arsenic. Specific brands named across sources include Three Musketeers, Snickers, Skittles, Nerds, Kit Kats, and Jolly Ranchers.

The reports highlight that some candies like Jolly Ranchers and Nerds exceeded the annual safe arsenic consumption limits for children when consumed in typical quantities. While the exact percentage varies slightly between sources (ranging from 60% to 80%), the figure of 78% aligns well within this range. The testing focused on 'elevated' levels relative to safety standards rather than outright toxic contamination.

The data comes from official Florida health officials' statements and detailed test results posted publicly. However, the reports do not provide detailed breakdowns for every brand listed in the claim, so while the named brands are confirmed to have elevated arsenic levels, the exact proportion of all tested brands with elevated arsenic is an estimate based on available data.
