Halloween
We kept seeing posts about arsenic in candy. So we tested some of them ourselves.
Canopy's heavy metals results for Nerds, Sour Patch Kids, a Hershey's snack-size bar, and Welch's Fruit Snacks.

Candy
The post says 36 pieces a year. Can you trust that number?
Viral Instagram posts say your kid can only eat 36 Sour Patch Kids a year before getting too much arsenic; the data behind them can't be checked and is far above what FDA and an independent retest found. Four Halloween candies are open for testing on Canopy now, with detection limits, benchmarks, and math shown, so you can get a number you can trust before October 31.
