At a Thanksgiving potluck, a handwritten dish card can help guests recognize what
is in the food, but it cannot establish that a dish is safe for someone with a food
allergy. The host should ask about allergies before the gathering, keep accurate
ingredient information available, and prevent serving utensils and food from crossing
between dishes. Guests managing an allergy still need to decide what they can eat
based on their own medical advice and the preparation details.

Start the conversation when people offer to bring a dish. Ask what ingredients it
contains, including sauces, toppings, spice blends, and packaged shortcuts. If the
cook does not know an ingredient or whether shared equipment was used, write down
the uncertainty instead of promising a food is free of an allergen.

## Ask Guests About Allergies Before You Plan the Menu

A simple note with the invitation works: “Please tell me about any food allergies
or dietary restrictions before we finalize the menu. We can discuss ingredients 
and whether you would prefer to bring your own food.” Keep that conversation private
and practical. Do not assume that avoiding one of the common allergens covers every
guest’s needs.

The FDA recognizes nine major food allergens for U.S. packaged-food labeling: milk,
eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame.
A guest may also need to avoid another ingredient, and an allergy is not the same
as a preference or intolerance. Use the FDA list as a reminder to check recipes,
not as a substitute for asking the person what they must avoid. See the [FDA food-allergies overview](https://www.fda.gov/food/nutrition-food-labeling-and-critical-foods/food-allergies).

## Write What You Know on Each Dish Card

Give each dish a plain name and list ingredients or known allergens in words that
guests recognize. A card saying “contains wheat and milk” is useful only if you 
have checked the full ingredient list and the cook has not substituted anything.
Keep the package or a photo of its ingredient label for sauces, broths, dressings,
bakery items, and spice mixes. Ingredients can change between purchases.

| Dish | Useful verified label | What still needs discussion | 
| Green bean casserole | Contains milk and wheat (when confirmed from the recipe) | Brand of soup and fried onions; shared utensils | 
| Sweet potato casserole | Contains egg and milk (if used) | Whether the topping also has tree nuts or other ingredients | 
| Stuffing | Contains wheat (if made with wheat bread) | Broth, sausage, butter, and other added ingredients | 
| Cranberry sauce | Ingredients: cranberries, sugar, water (only if this is the actual recipe) | Shared preparation equipment and any substitutions |

These are examples of _how to word labels_, not declarations about every version
of those foods. Never copy an example onto a dish without checking its actual recipe.
Do not describe a homemade dish as “allergy-safe,” “nut-free,” or “gluten-free” 
merely because a particular ingredient was omitted. Shared surfaces, utensils, or
prepared ingredients can introduce an allergen without making it obvious.

## Keep Ingredient Information With the Food

Ask each contributor to share the recipe or a brief ingredient list, including ingredients
within store-bought products. Keep that information next to the dish, in a small
folder, or in a message you can show guests. If someone replaces butter with a spread
or swaps a packaged mix, update the information before serving. For a household 
system that preserves package information, see [Pantry Labeling System for Allergens, Open Dates, and Rotation](https://lifeandwork.blog/pantry-labeling-system-for-allergens-open-dates-and-rotation-everyone-can-follow/).

The labeling rules that apply to commercially packaged foods do not make a homemade
tent card a certified safety declaration. Your aim is to communicate accurately 
and allow guests to ask questions. When the ingredients or preparation history cannot
be verified, say so plainly.

## Reduce Cross-Contact at the Thanksgiving Buffet

An otherwise suitable dish can pick up allergen proteins when a spoon moves from
the pecan topping to the potatoes, when food splashes into a neighboring tray, or
when ingredients share an unwashed board. This accidental transfer is often called
allergen cross-contact. Ordinary handwashing and thorough cleaning with soap and
water are necessary; removing a visible nut or wiping crumbs off a utensil does 
not make contaminated food safe.

 * Give each dish its own serving spoon or tongs and keep them with that dish.
 * Set nut-containing and other known-allergen dishes apart where spills or shared
   utensils are less likely.
 * Wash hands, counters, cutting boards, and utensils thoroughly before preparing
   food intended to avoid a particular allergen. Prepare and cover that food separately.
 * Do not allow guests to mix serving utensils. Replace any utensil that touches
   another dish.
 * For a guest with a serious allergy, discuss whether a separately prepared and
   served portion or a meal they bring themselves is a better arrangement than using
   the shared buffet.

Buffets create particular risks because guests serve themselves and utensils may
be switched without anyone noticing. [Food Allergy Research & Education](https://www.foodallergy.org/resources/avoiding-cross-contact)
explains why clean equipment and careful handling matter. [Food Allergy Canada](https://foodallergycanada.org/living-with-allergies/day-to-day-management/kitchen-tips-and-recipes/)
likewise recommends checking labels every time, using separate utensils, and preventing
cross-contact in preparation.

For placement, queues, and dish access, the related [Thanksgiving buffet layout guide](https://lifeandwork.blog/set-up-thanksgiving-buffet-better-traffic-flow/)
covers traffic flow. Keep the allergen signs close enough to the corresponding dishes
that nobody has to guess which label belongs to which tray.

## Have a Plan When a Guest Cannot Confirm a Dish

Do not pressure anyone to try a serving to be polite. If the recipe, packaging, 
or utensils are uncertain, offer the information you have and allow the guest to
decline. Guests with diagnosed food allergies should follow their personal emergency
and medication plan and bring prescribed emergency treatment if instructed by their
clinician. A handwritten food card is no substitute for that plan.

Packaged food labels may include precautionary “may contain” statements, but the
absence of such a statement is not a guarantee that an item is free of cross-contact.
If there is doubt, contact the manufacturer or ask the person with the allergy whether
the food fits their needs.

## A Short Setup Plan for Thanksgiving Day

Before guests arrive, place a dish-name card and verified ingredient details beside
each serving area. Set out separate utensils, keep packaged labels or recipe information
nearby, and check with contributors about last-minute substitutions. If a guest 
needs a separately handled meal, arrange its preparation and serving before the 
main buffet becomes crowded.

For take-home containers, keep the same accurate dish name and ingredient information
with the leftovers, and handle food promptly according to safe refrigeration rules.
