What We Wish We Knew About Cross-Contamination

Hi, it's Morgan & Allie 👋

Welcome to the very first issue of our newsletter. If you're new here: we're sisters, we both have celiac disease, and we started this site because we were tired of guessing whether a restaurant was actually safe. This first issue covers the thing that scared us most when we were newly diagnosed — cross-contamination — plus a few label-reading traps that still catch us off guard.

1. Cross-contamination 101

"Gluten-free" doesn't automatically mean safe. Cross-contamination happens when a gluten-free food comes into contact with gluten — even in amounts too small to see or taste. For someone with celiac disease, that contact can trigger an immune reaction and intestinal damage, even without obvious symptoms. Here's where it sneaks in most often:

Shared fryers. If breaded, wheat-containing foods (like regular chicken tenders or onion rings) are fried in the same oil as "gluten-free" fries, the fries are no longer safe. Always ask if the fryer is dedicated.
Toasters. One of the most common at-home offenders. Crumbs from regular bread linger in a toaster and transfer to anything toasted after. Keep a dedicated gluten-free toaster or use a toaster bag.
Cutting boards, colanders & utensils. Wooden and plastic surfaces can absorb gluten into scratches and pores that don't fully wash out. Colanders used to drain regular pasta are notorious for trapping starch in the mesh.
Shared condiments. Butter, jam, mayo, and peanut butter jars get "double-dipped" with a knife that touched regular bread first. We keep squeeze bottles or a dedicated labeled jar at home.
Flour in the air. Bakeries that handle wheat flour can have it airborne, settling on "gluten-free" display items nearby. This is exactly why we prioritize dedicated gluten-free kitchens in our restaurant guide.

2. "Gluten-friendly" is not the same as "gluten-free"

This one took us a while to learn the hard way. Some menus use soft language like "gluten-friendly," "gluten-conscious," or "made without gluten ingredients" — and none of those terms carry the same legal weight as "gluten-free."

Why the wording matters. In the U.S., the FDA's "gluten-free" food labeling rule requires the product to contain less than 20 parts per million (ppm) of gluten. Restaurants aren't required to test their food, but a kitchen that confidently uses the term "gluten-free" is generally signaling they've thought about ingredients and preparation. "Gluten-friendly" often just means gluten-containing ingredients were swapped out of a specific dish — with no promises about shared equipment, fryers, or prep surfaces. Treat it as a starting point for a conversation with your server, not a green light.

Our rule of thumb: when a menu says "gluten-friendly," we ask directly whether the kitchen can accommodate celiac disease specifically — not just a gluten-free preference. The answer tells us a lot.

3. Hidden gluten sources that surprise people

Soy sauce — traditionally brewed with wheat. Look for tamari labeled gluten-free instead.
Malt vinegar & malt flavoring — made from barley, a gluten grain. This includes malt vinegar chips and some cereals.
Regular oats — oats are naturally gluten-free, but are almost always cross-contaminated during farming, transport, or milling with wheat, barley, or rye. Only buy oats labeled "certified gluten-free."
Soup bases & broths — wheat flour is a common thickener in restaurant soups and gravies.
Medications & supplements — some use wheat starch as a filler or binder. Worth a quick check with your pharmacist if you take anything daily.
Seitan & some fake meats — seitan is literally made from wheat gluten. Always read plant-based meat labels closely.
Communion wafers & play-dough — not food-related exactly, but worth knowing if you or your kids come into contact with either.

4. How we order at a restaurant, every time

Call ahead, ideally during a slow period, and ask to speak with someone who knows the kitchen (a manager or chef, not just the host).
Say "I have celiac disease" instead of "I'm gluten-free" — it signals a medical need, not a lifestyle choice.
Ask specifically about shared fryers, shared water for boiling pasta, and shared prep surfaces.
When your food arrives, if anything looks off (breaded item on the same plate, croutons on a "GF" salad), send it back and ask for a remake.
Cross-check with the Find Me Gluten Free app before you go, especially for reviews left by people who specifically mention celiac disease.

What's next

In our next issue, we're breaking down how to read a nutrition label in under 10 seconds, plus our early days: what symptoms we ignored for way too long. If there's a topic you want us to cover, tell us on the contact page — we're building this newsletter around real questions from real people.

Eat well and stay safe out there, Morgan & Allie
