Gluten-Free, Halal, Vegan, Nut-Free: A Workplace Catering Cheat Sheet for Every Dietary Need
Ordering lunch for a team of 30 should not feel like defusing a bomb. But for many office managers and EA teams, that is exactly what it feels like when the dietary requirements start rolling in. Gluten-free, dairy-free, halal, vegan, nut allergy, low-FODMAP, and someone who is "mostly vegetarian but eats fish on Fridays."
The stakes are real. An allergic reaction is a medical emergency. Serving non-halal meat to someone who eats halal is a serious breach of respect. Forgetting the one coeliac on the team, again, tells them they are an afterthought.
This guide is a practical reference for anyone responsible for workplace catering in Australia. It covers the most common dietary requirements, how to collect information respectfully, how to avoid cross-contamination, and what to order when you do not have full information. Print it. Pin it to the kitchen noticeboard. Send it to your caterer.
Allergies vs Intolerances vs Lifestyle Choices
These three categories require different response levels, and conflating them creates problems in both directions.
Allergies are immune system responses that can be life-threatening. Peanut and tree nut allergies, shellfish allergies, and egg allergies can trigger anaphylaxis, which requires immediate treatment with adrenaline (EpiPen). Even trace amounts through cross-contamination can cause a reaction. Allergies require the highest level of caution. This is a medical safety issue.
Intolerances are digestive responses that are uncomfortable and sometimes debilitating but not immediately life-threatening. Lactose intolerance and coeliac disease (an autoimmune response to gluten) fall into this category. While not anaphylactic, coeliac disease causes serious intestinal damage with repeated gluten exposure. Intolerances require genuine accommodation, not dismissal.
Lifestyle choices include veganism, vegetarianism, and other dietary preferences based on ethical, environmental, or health considerations. These are personal decisions that deserve the same respect as any other. The accommodation may be simpler (no risk of anaphylaxis from accidental cheese), but the principle of inclusion is the same.
The practical rule: treat every stated dietary requirement as non-negotiable. You are not a doctor, and it is not your role to judge which requirements are "real enough" to accommodate. If someone says they cannot eat something, believe them and plan accordingly.
Common Dietary Requirements: A Quick Reference
| Requirement | What It Means | Common Triggers to Avoid | Notes |
|---|---|---|---|
| Gluten-free | No wheat, barley, rye, or oats (unless certified GF oats) | Bread, pasta, soy sauce, most baked goods, some sauces thickened with flour | Coeliac disease requires strict avoidance. Cross-contamination from shared cutting boards or fryers is a real risk |
| Halal | Prepared according to Islamic dietary law | Pork and pork-derived products (gelatin, lard), alcohol, non-halal slaughtered meat | Look for halal certification from a recognised Australian body. "No pork" is not the same as halal |
| Kosher | Prepared according to Jewish dietary law | Mixing meat and dairy, shellfish, pork, non-kosher slaughtered meat | Kosher requirements are complex. For observant employees, source from a kosher-certified caterer |
| Vegan | No animal products of any kind | Meat, fish, dairy, eggs, honey, gelatin, some food colourings (carmine) | Check sauces and dressings, which often contain dairy or egg |
| Vegetarian | No meat or fish | Meat, poultry, fish, shellfish, gelatin, animal-derived rennet in some cheeses | Some vegetarians eat eggs and dairy (lacto-ovo). Some do not. Ask |
| Nut-free | No tree nuts or peanuts | Peanuts, almonds, cashews, walnuts, pistachios, pine nuts, pesto, satay sauce, marzipan, praline | This is frequently an allergy-level requirement. Cross-contamination is a serious concern |
| Dairy-free | No cow's milk or products derived from it | Milk, cheese, butter, cream, yoghurt, whey, casein | Check labels carefully. Dairy appears in many processed foods under various names |
| Low-FODMAP | Avoidance of certain fermentable carbohydrates | Onion, garlic, wheat, certain fruits (apples, pears), legumes, lactose | Developed by Monash University in Melbourne. Common for people managing IBS. The restricted list is specific and sometimes counterintuitive |
How to Collect Dietary Information Respectfully
The way you ask matters as much as the fact that you ask.
Use a standard form for everyone. Do not single out people who "look like" they might have dietary requirements. Send a simple form to the entire team. A Google Form or similar tool with checkboxes for common requirements and a free-text field for specifics works well.
Keep it simple and judgment-free. The form should ask what people cannot or do not eat, not why. "Please list any dietary requirements or restrictions" is sufficient. Nobody should have to justify their needs to the office catering coordinator.
Store the information securely. Dietary information can reveal religious beliefs, medical conditions, and personal values. Treat it as personal information under the Privacy Act 1988. Store it in a secure location, limit access to the people who need it for catering purposes, and do not share it casually.
Update regularly. Dietary requirements change. People develop new allergies, adopt new diets, or receive new diagnoses. Send the form out at least twice a year, or whenever there is a significant team change. A quick annual refresh takes five minutes and prevents the "I told you about my allergy when I started two years ago" situation.
Confirm before every catered event. Even with a standing record, confirm requirements before each event. A brief message asking "any changes to dietary requirements since last time?" takes seconds and catches updates.
Cross-Contamination Basics
For employees with allergies, the difference between a safe meal and a trip to the emergency room can come down to whether someone used the same tongs for the regular and nut-free options. Cross-contamination is the most common way workplace catering goes wrong.
Use separate serving utensils. Every dish should have its own serving spoon, tongs, or ladle. Utensils should be clearly matched to their dish, not left floating between options.
Set out allergen-free options first. When laying out a buffet, place allergen-free and dietary-specific items at the beginning of the line, before the general options. This reduces the chance of crumbs, drips, or splashes from other dishes contaminating them.
Keep packaging for allergen-free items. If food comes from a caterer in labelled packaging, keep that packaging visible at the event. It lets people with allergies verify ingredients themselves, which many prefer to do.
Cover allergen-free items. Use lids, cling wrap, or domes on dishes designated for specific dietary requirements. An uncovered platter of gluten-free sandwiches next to a platter of regular sandwiches is one accidental bread crumb away from a problem.
Label everything. Every single dish at a workplace event should have a label listing the dish name and the major allergens it contains or is free from. Use a consistent format. The FSANZ (Food Standards Australia New Zealand) list of major allergens is a good starting framework: gluten, crustaceans, eggs, fish, milk, peanuts, soybeans, tree nuts, sesame, lupin, and sulphites.
Separate preparation areas. If food is being prepared onsite (even just assembled), use separate cutting boards and preparation areas for allergen-free items. Wash hands between handling different types of food.
When You Do Not Know Everyone's Requirements
Sometimes you are catering for a large group, a client event, or a situation where collecting individual requirements is not practical. In those cases, aim for a safe default spread.
The 30/2-3/avoid/halal/label rule:
- 30% of food options should be vegan. Vegan food is safe for vegetarians, many allergy sufferers, and people with dairy or egg intolerances. It is the most broadly inclusive single category.
- 2-3 clearly labelled gluten-free options. At least one should also be vegan for maximum coverage.
- Avoid nuts entirely unless you are certain no one with a nut allergy is attending. The risk-to-benefit ratio is not worth it.
- Order halal meat if serving meat. Halal meat is acceptable to most people, while non-halal meat excludes observant Muslim attendees. If kosher attendees are expected, provide a separate kosher option from a certified provider, as halal and kosher are different standards.
- Label everything. Even a simple handwritten card listing ingredients covers most situations.
This approach will not be perfect for everyone, but it will avoid the most common failures and demonstrate that you have thought about inclusion.
The Workplace Catering Checklist
Planning Phase (1-2 weeks before)
- Confirm or collect dietary requirements from all attendees
- Review the dietary requirements spreadsheet for any updates
- Determine the total headcount and the percentage breakdown by dietary need
- Choose a caterer who can accommodate the required range (see questions below)
- Set budget, keeping in mind that dietary-specific items sometimes cost more
- Plan the layout so allergen-free items are separated and clearly marked
Ordering Phase (3-5 days before)
- Place the order with specific dietary requirements itemised, not just a note saying "some dietary needs"
- Confirm the caterer understands the difference between "no gluten ingredients" and "prepared in a gluten-free environment"
- Request individual packaging or clear labelling for dietary-specific items
- Order slightly more of dietary-specific options than you think you need (running out of the one gluten-free option is a surefire way to make someone feel excluded)
- Confirm delivery time and any special handling instructions
Setup Phase (day of event)
- Set out dietary-specific items first, in a designated area
- Place labels on every dish
- Assign separate serving utensils to each dish
- Cover or protect allergen-free items from cross-contamination
- Brief any staff or volunteers on the layout and which items are for specific requirements
- Keep a printed list of ingredients or allergen information accessible
After the Event
- Note what worked and what did not for future reference
- Record any dietary requirement changes flagged during the event
- Thank the caterer and provide feedback on dietary accommodation quality
- Ask attendees for quick feedback (was your dietary requirement met?)
Five Questions to Ask Your Caterer
Before you commit to a catering provider, ask these questions. The answers will tell you whether they can genuinely accommodate dietary needs or whether they will nod and then send the same platter they send to everyone.
-
How do you handle allergen-free preparation? You want to hear about separate preparation areas, dedicated utensils, and staff training. "We just leave the nuts out" is not a sufficient answer for someone with an allergy.
-
Do you have halal and/or kosher certification? If they claim to offer halal or kosher options, ask for evidence of certification. Self-declared halal without certification is not reliable for observant employees.
-
Can you provide individual packaging for dietary-specific items? Individually wrapped or boxed items are the safest option for people with allergies, as they eliminate buffet-style cross-contamination risk entirely.
-
How do you label your food? Ideally, every item comes with a label listing ingredients and common allergens. If the caterer does not provide labels, you will need to create them yourself.
-
What is your process if a dietary requirement cannot be met? A good caterer will tell you upfront if they cannot safely accommodate a specific need rather than guessing. This gives you time to source an alternative.
A Note on Cost and Equity
Dietary-specific catering sometimes costs more per head than standard options. This is not a reason to provide lesser quality or smaller portions for people with dietary requirements. If the team gets gourmet sandwiches and the one coeliac gets a sad, cling-wrapped rice cracker with hummus, the message is clear: your needs are an inconvenience.
Build the cost of inclusive catering into the standard catering budget, not as a separate line item that needs justifying. Inclusive catering is not a premium add-on. It is the baseline for professional workplace events.
Keep This Guide Handy
Workplace catering does not need to be stressful. With a current dietary requirements list, a reliable caterer, clear labelling, and basic cross-contamination awareness, most events can be handled smoothly. The effort you put into getting it right tells every employee the same thing: we thought about you.
