Is it safe to buy bulk spices from small grocery stores?

What's actually in it

Turmeric, paprika, cumin, and cinnamon are sometimes cut with lead chromate or lead oxide at the source to brighten the color or bulk up the weight. The practice isn't legal in the US, but imported spices can be treated before they arrive and end up on a store shelf. Small ethnic markets and bulk bin sections have less regulatory oversight than big chain groceries, so contaminated lots are more likely to reach the shopper.

Spices are used in small amounts, which sounds reassuring. But a daily teaspoon of contaminated turmeric adds up like any other lead source.

What the research says

A 2026 study in Biol Trace Elem Res tested spices sold in the Las Vegas market and measured lead plus several other trace elements. A meaningful share of samples had lead levels above health-based limits, especially in ground turmeric and some red chili blends. The risk assessment flagged regular users, including pregnant women and young children, as the groups where intake mattered most.

For peace of mind, look for spice brands that publish third-party heavy metals testing (Penzeys, Diaspora, and a few others). Whole spices ground at home are safer than pre-ground because adulteration is easier to spot. Consumer Reports publishes periodic spice lead test results that can guide brand choice. Avoid bright yellow turmeric and intensely red paprika sold without labels.
