As I understand it, that lead contaminated cinnamon was found in dollar-store apple sauce packaged for children - and they only found it because some of the kids eating it started to show symptoms of lead poisoning. Given that it was for a dollar store, I'd expect the manufacturer was *very* price sensitive on ingredients so this was the absolute cheapest cinnamon they could source.

I have heard nothing about contamination in cinnamon being sold as cinnamon in US supermarkets.

If you're concerned about lead, consider buying cinnamon as rolls of bark* and either grinding it or throwing it in a blender. Or buying it from a reputable supplier like Penzeys. Or switching to the more expensive 'true' cinnamon (cinnamomum verum) AKA 'Ceylon' cinnamon. Ceylon is now Sri Lanka and I get my cinnamon either directly from a producer there (Druera) or from Penzey's Spice. Both are very good.

All that said, Consumer Reports recently tested cinnamon brands for lead. They found that Paras had the highest lead concentration, at 3.52 ppm. Then, from highest lead level to lowest, were EGN, Mimi’s Products, Bowl & Basket, Rani Brand, Zara Foods, Three Rivers, Yu Yee Brand, BaiLiFeng, Spicy King, Badia, and Deep.

The FDA issued a 'voluntary recall' for ground cinnamon from the brands Compania Indillor Orientale, ALB Flavor, Shahzada, Spice Class, La Frontera, El Chilar, Marcum, SWAD, and Supreme Tradition.

I'll confess to having used both Deep (local South Asian store) and Badia (online store for restaurant products) - but check your pantry for both the FDA recall names and the ones CU found lead in. I'd note that neither mentions McCormack - which seems to be the most common supermarket spice brand here in New England. (no idea about the rest of the country — who goes to the supermarket for spices when traveling?)

*there are two ways for lead to get into cinnamon. One is like cadmium in cocoa: it's in the ground / water and the plant takes it up. This seems to play a minor role in cinnamon contamination. The rest is either from processing, storage, or direct adulteration. Grinding your own gets you past the latter set of issues.
