βKey Takeaways
When you start a gluten-free diet, the focus is naturally on the obvious culprits: bread, pasta, and baked goods. You clean out your pantry, buy π gluten-free soy sauce, and start cooking whole foods from scratch.
You grill a piece of chicken, season it with garlic powder, paprika, and a taco seasoning packet. An hour later, you are violently ill.
Why? Because the spices you used were contaminated with wheat flour.
While pure, single-ingredient spices should be naturally gluten-free, the reality of global spice manufacturing makes your spice cabinet a major risk area for cross-contamination. Here is how to navigate it safely.
Why Would Gluten Be in Spices?
There are two main reasons gluten ends up in spices:
1. Intentional Fillers (Anti-Caking Agents)
Spices are sold by weight. Unscrupulous manufacturers, or those producing very cheap spices, will sometimes cut their ground spices with wheat flour to bulk up the weight and save money. Furthermore, wheat starch is sometimes used as an anti-caking agent to prevent spices like garlic powder or onion powder from clumping in humid environments.
2. Cross-Contamination in Manufacturing
This is the biggest risk. Spices are usually processed in massive facilities that also handle wheat, barley, and rye. A machine that grinds wheat into flour in the morning might be used to grind cumin in the afternoon. If the machines are not properly sterilized, your cumin will be heavily cross-contaminated.

The Rule of Thumb: Single Spices vs. Blends
Single-Ingredient Spices (Generally Safer)
Whole spices (like whole peppercorns, whole cumin seeds, or cinnamon sticks) are the safest option because they haven't been ground on shared machinery.
Ground single-ingredient spices (like ground cinnamon, oregano, or basil) from reputable brands are generally safe, but you should still check for "processed in a facility" warnings.
Spice Blends and Seasoning Packets (Extremely High Risk)
This is where celiacs get caught. Taco seasoning, chili powder, curry powder, poultry seasoning, and generic "steak rubs" frequently contain hidden gluten.
Manufacturers use wheat flour to thicken the blend or as a carrier for flavor extracts. Never use a seasoning packet unless it is explicitly labeled "Gluten-Free."

Celiac Safety Glossary
- Celiac disease
- Celiac disease is a serious autoimmune disorder in which ingesting gluten β a protein found in wheat, barley, and rye β triggers an immune response that damages the small intestine's villi, affecting approximately 1 in 100 people worldwide according to the Celiac Disease Foundation.
- Gluten
- Gluten is a family of storage proteins (prolamins and glutelins) found naturally in cereal grains like wheat (including varieties like spelt, kamut, and farro), barley, and rye, which acts as a binder to give food elasticity and shape.
- Cross-contamination
- Cross-contamination (or cross-contact) occurs when gluten-free food comes into contact with gluten-containing food or surfaces β such as shared cutting boards, toasters, fryers, or utensils β rendering otherwise safe food dangerous for people with celiac disease.
- Gluten-free certification
- Gluten-free certification, such as the GFCO (Gluten-Free Certification Organization) seal, verifies that a product contains fewer than 10 parts per million (ppm) of gluten β stricter than the FDA's 20 ppm threshold for "gluten-free" labeling.
- Malt (Barley)
- Malt is fermented barley used as a flavoring or sweetener in cereals, chocolates, and beer; it is a major source of hidden gluten that is often overlooked on ingredient lists.
- Wheat starch
- Wheat starch is wheat flour that has had the gluten protein washed out. While some European gluten-free foods use codex-grade wheat starch (tested below 20 ppm), it can still trigger reactions in sensitive individuals.
