A customer asks about allergens. Can your cafe give a reliable answer?

Allergen questions in a cafe rarely arrive with much warning. A customer wants to know whether today's muffin contains sesame, whether the aioli has egg, or whether a dish can really be made dairy-free. In that moment, the legal and practical issue is not how confident the answer sounds. It is whether your business has a current, reliable basis for what staff are saying.

For New Zealand food service, unpackaged food does not escape allergen-information obligations just because it is sold over the counter. Where food is not in packaging or does not need a label, allergen information must be displayed with the food or available on request. That makes recipe control, supplier checks and a clear front-of-house to kitchen checking path especially important.

The safest approach is to answer from current ingredient and preparation information, update that answer when substitutions happen, and be candid about any cross-contact limits your kitchen cannot rule out. For businesses operating under a Food Control Plan or National Programme, that is part of practical allergen management, not just good customer service.

What you need to be able to tell a customer

For food prepared and sold by your cafe without packaging or a required label, allergen information must either be displayed with the food or be available on request. Your team needs a reliable way to provide that information for the item being ordered.

That means your team should be able to check whether an allergen may be present directly in the dish, such as milk in a sauce or egg in aioli, and whether it may be present indirectly through shared preparation, utensils, fryers or surfaces.

In practice, a reliable answer usually depends on four things:

• the current recipe used for that exact dish
• the current ingredients and any supplier substitutions
• how the dish is prepared, including shared equipment or work areas
• whether front-of-house staff know when they must ask the kitchen instead of guessing

That on-request route is different from the packaged-food label rules. Some cafes also choose to use menu icons or descriptions such as dairy-free. If you use them, they must still be accurate.

Unlabelled meals and packaged food are treated differently

Many hospitality businesses deal with both prepared meals and packaged items, so it helps to separate the rules.

For packaged food that must carry a label, allergen information has to be declared in plain English. Food Standards Australia New Zealand: Allergen labelling for consumers says labels must identify allergens and include a separate summary statement beginning with the word contains near the ingredient list. For cereals containing gluten, the summary statement uses the word gluten. Check each packaged product against the current allergen declaration requirements rather than assuming an older label is still suitable.

That packaging system does not apply in the same way to food served without packaging or food that does not need a label, such as a meal plated in your cafe or food prepared in a takeaway context. For that kind of food, allergen information must be displayed with the food or available on request from the business selling it.

So if you sell a labelled retail brownie at the counter, the packaging rules matter. If you serve an unlabelled brownie from the cabinet, what matters is whether your staff can give accurate allergen information when asked. If you also package food for retail sale, our broader NZ labelling and packaging guide covers other label questions beyond allergens.

This distinction is where businesses often slip up. A team member may point to a packaged product rule, a menu symbol, or a general sign near the till, when the customer is actually asking about the specific item they are about to eat. Answer for the product and recipe being served today.

Why menu claims like dairy-free or gluten-free need evidence

If you choose to describe a dish as dairy-free, gluten-free or similar, that is a representation to customers. The Commerce Commission's guidance on making accurate claims says businesses need reasonable grounds for claims at the time they make them.

For a cafe, reasonable grounds usually means more than good intentions. You need a sensible basis for the statement, such as a checked recipe, supplier information for each ingredient, and a preparation method that matches the claim you are making.

That does not mean you can never use these terms. It means you should use them carefully and only to the extent you can support them. If your almond slice contains no dairy ingredients but is made on the same bench as cheesecakes, your team should not turn dairy-free into a broad assurance without explaining the cross-contact risk.

The same applies to general wording such as may contain. On packaged foods, may contain statements are voluntary and not regulated by the Food Standards Code. In food service, a sign or verbal caveat of that kind is not a substitute for checking the actual dish. It also does not solve a misleading claim if the rest of your wording suggests more certainty than your kitchen can prove.

If staff cannot verify a requested assurance, they should say so clearly. An honest answer is: "We cannot confirm this dish is free from sesame because the dressing was changed and we have not checked the new bottle." That is far better than a quick guess.

Set up a counter-to-kitchen checking path

When a customer asks about an allergen, the biggest risk is often the handover between the person serving and the person preparing the food. A prudent process can reduce that risk without pretending there is a perfect script for every venue.

Start with a simple rule for staff: do not answer from memory if there is any doubt. The question should move to the person who can check the current recipe and preparation method.

For many cafes, that means having:

• a current recipe file or menu matrix for each dish
• ingredient specifications for bought-in items such as sauces, breads, spice blends and desserts
• a way to note known cross-contact points, such as shared fryers, sandwich presses or bakery cabinets
• a clear internal process for recording supplier substitutions and temporary menu changes

Front-of-house staff should know the difference between direct ingredients and indirect presence. A muffin may not include peanuts in the recipe, but if it is displayed and handled beside peanut products, that can still matter to the customer.

Kitchen staff should also know when a dish can be adapted and when it cannot. Removing feta from a salad may be straightforward if the rest of the ingredients are separate. It is very different if the dressing itself contains dairy or if the salad has already been mixed in a shared bowl.

The aim is not to create a thick manual nobody uses. The aim is to make sure the person speaking to the customer can get a current, practical answer from the people and records closest to the food.

What to say when ingredients or suppliers have changed

Ingredient substitution is one of the most common reasons allergen information becomes unreliable. A supplier runs out of a sauce, your chef buys a replacement, and the menu description stays the same. That is exactly when a customer can receive an answer that was true last week but wrong today.

A useful habit is to treat any changed ingredient as a trigger for a quick allergen check and a team update before service. The question is simple: does the new ingredient change what we can say about this dish?

Take a practical example. Your menu says a chicken wrap can be made dairy-free by leaving out the cheese. A customer asks if that is still possible today. The kitchen has switched to a new peri peri sauce because the usual supplier was unavailable. The old sauce had no milk ingredients. The new one includes milk powder.

The reliable answer is not, Yes, just remove the cheese. It is something like: Usually we can make this without cheese, but the sauce we are using today contains milk, so we cannot say this version is dairy-free.

That kind of answer may feel less sales-friendly in the moment, but it is accurate, useful and much safer from both a customer care and legal point of view.

The same principle applies when the issue is uncertainty rather than a confirmed allergen. If you cannot confirm whether the crumb coating includes sesame because the outer carton was discarded and no specification is on file, say that you cannot verify it and offer another item only if you can answer for that item properly.

Train staff to avoid reassurance they cannot substantiate

Customers asking about allergens are often looking for confidence and clarity. Your team can provide that without overstating what the business knows.

Helpful language is specific and factual. For example:

• This cake contains almond meal and is displayed beside other nut products.
• The soup recipe does not include egg, but it is served with bread from a supplier and we need to check that product information.
• We can remove the yoghurt, but the marinade already on the chicken contains milk.
• We cannot guarantee this item is free from gluten because it is prepared in a shared area and we cannot verify it to that level.

Less helpful language is broad reassurance such as "it should be fine", "I think it is dairy-free", or "our gluten-free options are completely safe". Those phrases create certainty without a proper basis.

Food Standards Australia New Zealand's food-service guidance stresses accurate, up-to-date allergen information, staff training and communication about allergens that may be present directly or indirectly. That is a sensible operating standard for cafes and restaurants even before you get to any dispute about what was said at the counter.

Review the wording you already use

Many businesses already have menu notes, social posts, cabinet labels, online ordering pages or verbal scripts that mention allergens. The question is whether those statements match how the food is actually bought, prepped and served today.

Review any wording such as dairy-free, gluten-free, nut-free, vegan-friendly, made without egg, or suitable for allergies. Check whether you have current grounds for each statement and whether any qualification is needed.

Also look at operational points that can quietly undermine your answer, such as supplier substitutions, relabelling of house-made cabinet food, shared utensils, buffet service, and specials prepared by different staff. If your process is strong but your wording overpromises, the wording needs work. If your wording is careful but nobody updates recipe information when ingredients change, the process needs work.

Key Takeaways

• For unpackaged cafe and restaurant food, allergen information must be displayed with the food or available on request, so staff need a dependable way to answer about the item actually being served.
• A reliable answer depends on current recipes, current supplier ingredients, and a process for updating the team when substitutions or specials change that position.
• Claims such as dairy-free or gluten-free need reasonable grounds when made and should not promise more than your kitchen can verify.
• Cross-contact matters as well as direct ingredients, so shared benches, utensils, fryers and display areas may need to be explained honestly.
• If staff cannot confirm an assurance, the safer response is to say that clearly rather than guess or offer broad reassurance.
