Sulphites in Food FAQ, Your Questions Answered

Straight answers about the food allergen awareness course for Ireland learners: local acceptance, online delivery, certification and pricing at Online Safety Courses.

No. The proteins that cause allergic reactions survive cooking, frying, baking and freezing. Heat does not make a food safe for a person who is allergic to it, and oil used to fry one food carries its allergens into the next.

Not in Ireland. Irish regulations require allergen information for non prepacked food to be provided in writing, for each item, where the customer can find it easily before ordering. Staff can explain it, but spoken information alone does not meet the law.

For some people a very small amount: a trace on a knife, a few crumbs or a splash of milk. The amount differs from person to person and from day to day, so there is no safe level a kitchen can rely on. The aim is always to keep the allergen out altogether.

Why Choose Us

Why Take Your Allergen Course with Online Safety Courses?

Discover why workers and businesses in Ireland, from Dublin, Cork, Galway and beyond, choose Online Safety Courses for food allergen awareness training.

The food allergen awareness course at Online Safety Courses fits Ireland working life perfectly. From Dublin's construction cranes and Cork's pharma plants to Galway's medtech campuses, Limerick's manufacturing belt and the farms, hotels, warehouses and hospitals in every county between, Irish workplaces run on certified, compliant staff. Instead of losing a day to a classroom, learners in Ireland complete the full accredited training online, in about 1-2 hours, from home or straight from the workplace.

Local employers know exactly what they are looking at when your certificate arrives: CPD Certified, RoSPA approved, HSA aligned training from a provider used by businesses across every county in Ireland. The unique verification code on every certificate makes checks instant, whether you work in Dublin, Cork or Galway.

For businesses, the free Employer Dashboard turns a team rollout into one afternoon of work: bulk registration, live progress and every food allergen awareness certificate in one clean screen, with automatic volume discounts applied at checkout.

This food allergen awareness course was designed around real hospitality schedules: split shifts, weekend service and no spare afternoons. Every lesson streams on any device, every pause saves your place, and nothing needs installing. HD video and interactive questions make the 14 allergens, cross contact and labelling law genuinely memorable.

The syllabus tracks exactly what Irish EHOs expect: each allergen and its hiding places, reaction and anaphylaxis response, separation and cleaning routines, declaration rules under Regulation 1169/2011 and confident customer communication. Scenes come from real Irish kitchens, delis and counters.

Whether you are a barista fielding your first allergen question or a catering manager certifying a brigade, the allergen training flows without friction from registration to certificate.

A classroom allergen day means lost shifts, travel and cover costs, multiplied by every team member and repeated every 3 years. The online allergen course removes all of it. Staff certify from home or the staff room, starting the moment you enrol them.

Managers see each completion in real time and can show an EHO the complete allergen training record in seconds. Stack the automatic volume discounts on top and this becomes the most economical accredited allergen training available in Ireland.

Pricing is honest: one figure covers the full course, unlimited retakes and the instant allergen awareness certificate. No add ons, ever.

Hospitality rotas leave no room for fixed course dates. The self-paced allergen awareness course lets you move at whatever speed suits, pausing on any device and resuming exactly where you left off, after close, before opening or on the bus home.

A clear progress tracker shows how much of the allergen training remains and how close the certificate is. Most learners finish inside 1-2 hours; others spread it across a few breaks. Both work perfectly.

Assign it to staff and they will slot it around the rota without disrupting service, one of the main reasons Irish food businesses return to Online Safety Courses year after year.

There is no waiting around. Pass the assessment and the digital allergen awareness certificate is generated on the spot, aligned with Irish and EU food law and recognised across Ireland, the UK and Europe.

It lives permanently in your account for re-download during EHO inspections, job applications and insurance renewals, and its unique verification code lets any inspector confirm it instantly.

Paired with a HACCP certificate, it forms the standard food industry double that every Irish kitchen and food shop expects to see.

Every module comes from licensed, Chartered (CMIOSH) consultants who know exactly how allergen incidents happen in real kitchens: the shared fryer, the dusted worktop, the garnish nobody mentioned.

That experience shows: you learn where each of the 14 allergens hides in everyday menus, how one shared spoon can trigger anaphylaxis, the cleaning and separation habits that survive a Friday rush and the exact words to use when a customer asks. Irish kitchen scenarios drive every lesson home.

Content is re-reviewed against current Irish and EU food legislation and national food safety guidance, so the allergen course never drifts out of date.

The platform never closes, which suits an industry that barely does either. Start the allergen training after service, continue before opening and finish on a day off, whatever rhythm the rota allows.

Progress syncs across every device automatically, so switching from phone to laptop mid module is seamless. Split shift and weekend staff get exactly the same premium experience.

Teams can also reopen the 14 allergens module before a menu change or an inspection, turning the allergen course into a living reference rather than a one time event.

Online Safety Courses has certified more than 749,500 learners across Ireland, the UK and Europe, with a 98% pass rate and a 4.9 star average from verified Google reviews we cannot edit or hide.

From Dublin to Cork, Galway to Limerick and Waterford to Belfast, our allergen training helps Irish food businesses serve allergic customers safely and confidently.

Food businesses come back because it simply works: clean records, instant certificates and a support team that answers.

Everyone who prepares, serves or sells food. EU Regulation 1169/2011 makes allergen information mandatory, and the national food safety authority expects trained staff behind every menu declaration and every answer at the counter.

In practice, the people certifying with us are chefs and cooks, kitchen porters, waiters and baristas, deli and counter staff, supermarket workers, food truck operators, market traders and caterers in schools, hospitals and care homes.

Allergen training pairs naturally with HACCP as the food industry standard, and the automatic discounts reward taking both for every team member. Our Irish support team can help you roll it out.

Essential Knowledge

Sulphites in Food

How allergens reach a plate by accident, what the law requires a food business to tell its customers and how to serve them safely.

Sulphur dioxide and sulphites

Sulphur dioxide and sulphites are preservatives. They must be declared as an allergen where they are present at more than 10 milligrams per kilogram or per litre in the finished food. In sensitive people, particularly some with asthma, they can trigger wheezing and breathing difficulty.

  • Wine, cider and beer.
  • Dried fruit, such as apricots, raisins and prunes.
  • Prepared potatoes, including some chips and peeled potatoes.
  • Sausages and burgers.
  • Pickles, vinegar, sauces and cordials.
  • Prawns and other shellfish.

On labels they appear by name or by number, E220 to E228.

Hidden sources of allergens

  • Milk: in bread, crisps, processed meats, stock cubes and "non dairy" creamers.
  • Egg: in pasta, mayonnaise, glazes on pastry and some wines.
  • Gluten: in soy sauce, gravy, sausages, stock and beer.
  • Soya: in bread, chocolate, sauces and vegetarian products.
  • Nuts: in pesto, marzipan, praline, nut oils and curry pastes.
  • Fish: in Worcestershire sauce, Caesar dressing and some stocks.
  • Celery: in stock cubes, soups and spice mixes.
  • Mustard: in dressings, marinades and processed meats.
  • Sesame: in houmous, tahini, bread and oil.

Compound ingredients are where allergens hide. Read the full label of every bought in product, and read it again when the brand or the pack changes.

Allergen cross contact

Cross contact is the accidental transfer of an allergen from a food that contains it to a food that does not. It is the allergen equivalent of cross contamination, with one important difference: cooking kills bacteria, but it does not destroy an allergen.

  • Shared chopping boards, knives, tongs, spoons and probes.
  • Shared fryer oil, grills, toasters and sandwich presses.
  • Hands, gloves, aprons and cloths.
  • Flour dust, splashes and steam.
  • Crumbs in butter, spreads and shared containers.
  • Garnishes and sauces added at the pass.
  • Open storage, with one ingredient spilling into another.

The law on allergen information

Regulation (EU) No 1169/2011 requires food businesses to tell consumers when any of 14 named allergens has been used as an ingredient or a processing aid. On prepacked food the allergens are emphasised in the ingredients list, usually in bold.

For food sold loose, such as meals in restaurants, takeaways and delicatessens, Irish regulations made in 2014 go further than the European minimum. The information must be in writing, for each item, at the point where the food is presented, ordered or supplied, and it must be easy to find without the customer having to ask. It may be on the menu, on a board, on a label or in an allergen folder. Environmental Health Officers check it during inspections.

A trace is enough

A crumb, a smear or a shared spoon can cause a severe reaction.

In writing

In Ireland allergen information for loose food must be available in writing before the customer orders.

Never guess

If you cannot be sure a dish is safe for a customer, say so.

The accredited Food Allergen Awareness Course covers the 14 allergens, the law on allergen information and how to prevent cross contact, in about an hour online, with a CPD certified certificate the moment you pass.
