What Warning Should Irish Food Businesses Display for Glycerol Slush Drinks?

An Irish food business selling unpackaged slush ice drinks that contain glycerol should display a clear, permanent warning at the point of sale: “This product contains glycerol and is not recommended for children aged 10 and under.” The warning should be visible before purchase, remain in place during trading and be supported by reliable product information, staff awareness and supplier records.

TapTick can help an operator schedule point-of-sale checks, record supplier and dilution information, and connect a missing warning or incorrect set-up to a corrective action. It does not verify a formulation, calculate glycerol exposure or replace supplier information and FSAI guidance. See the TapTick features.

What warning should be displayed?

FSAI advises retailers selling unpackaged slush ice drinks containing glycerol to display this wording at the point of sale:

“This product contains glycerol and is not recommended for children aged 10 and under.”

The notice should be clear, permanent and visible to customers before they buy the drink. FSAI specifically advises replacing temporary paper notices with something that can withstand handling and everyday wear and tear. A sign behind a machine, inside a staff folder or below the customer’s normal line of sight does not achieve the practical purpose of a point-of-sale warning.

The current Irish advice applies to glycerol-containing slush ice drinks. Do not display the warning automatically beside a product that does not contain glycerol, and do not assume every slush product uses the same formulation.

Is the warning a legal requirement?

The distinction matters. Glycerol is an authorised food additive in the European Union. For flavoured drinks it is permitted under the “quantum satis” principle, so Regulation (EC) No 1333/2008 does not set a single numerical maximum for this use. Businesses must still use it according to good manufacturing practice, at no more than the level needed to achieve its purpose, and without misleading consumers.

Article 14 of Regulation (EC) No 178/2002 places the primary legal duty on food businesses not to place unsafe food on the market. FSAI says its 2026 advice was developed to support manufacturers, importers, distributors and retailers in meeting that duty after a new European Food Safety Authority (EFSA) assessment of acute exposure.

The recommended point-of-sale wording and the advice to avoid refill promotions are FSAI risk-management guidance. They should not be described as a new statutory ban on selling slush drinks to children. An operator should nevertheless treat current regulator guidance as an important control, document how it is followed and keep watching for changes to law or official advice.

How do you know whether a product contains glycerol?

Start with the exact syrup, concentrate or ready-to-drink product in use. Check the label, specification and supplier information for the terms “glycerol”, “glycerine”, “glycerin” or “E 422”. Do not rely on the brand name, flavour, colour or whether the product is advertised as low sugar or zero sugar.

For a machine product, keep the current specification and preparation instructions where the manager and staff can access them. When the supplier changes a recipe, the business should review the point-of-sale information and operating procedure before putting the new stock into use.

If the business cannot confirm whether a product contains glycerol, pause and obtain written clarification from the supplier. Staff should not reassure a parent or caregiver based on memory or on information for a different flavour or formulation.

What should you do about refills and portion sizes?

FSAI advises businesses to avoid free refills, unlimited refill promotions or similar marketing for glycerol-containing slush ice drinks in premises where children may consume them. Repeated servings over a short period can increase acute exposure, while cup sizes in the market may be larger than the 250 mL child serving used in EFSA’s assessment.

Practical controls include:

• removing unlimited-refill messaging for glycerol-containing products;
• making cup sizes clear to staff and customers;
• checking that promotions, meal deals and self-service instructions do not conflict with the warning;
• avoiding casual “top-ups” for children; and
• including the warning and refill control in the site’s opening check.

The FSAI advice is aimed at managing exposure, not at turning counter staff into age-verification officers. A business should set a simple, consistent procedure and train staff to explain the advice calmly.

What should a daily check cover?

A short opening or pre-service check can prevent the warning and product set-up from drifting out of control. Record:

• the product, flavour and supplier batch in use;
• whether glycerol or E 422 is present;
• that the correct warning is visible at the point of sale;
• that the notice is legible, clean, undamaged and not obscured;
• that the syrup is being diluted and prepared to the supplier’s current instructions;
• that the correct cup or portion options are available;
• that refill or promotional messaging is appropriate; and
• who completed the check and what action was taken if something was wrong.

A tick by itself is weak evidence when a problem is found. Record the exception—for example, “warning missing after machine move”—then record the immediate action, owner and verification that the correction was completed before sales resumed.

What should staff know?

Staff do not need to explain the toxicology. They do need a reliable answer to common customer questions and a clear escalation route. Training should cover:

• which products contain glycerol and where the information is kept;
• the exact FSAI warning for children aged ten and under;
• why the business does not offer free or unlimited refills for the product;
• how to follow the supplier’s preparation and dilution instructions;
• what to do if the warning is missing or the product cannot be identified; and
• who to contact if a customer reports illness.

Do not ask staff to improvise medical advice. If a customer asks whether a particular child can safely consume the product, staff should explain the FSAI advice and point to the warning rather than give a personal assurance.

What supplier and product records should be kept?

Keep enough information to show what was sold, how it was prepared and what the business knew at the time. Useful records include:

• current and previous product specifications;
• ingredient lists and glycerol concentration information supplied by the manufacturer;
• batch, delivery and traceability records;
• preparation and dilution instructions;
• copies or photos of the point-of-sale warning;
• staff briefing or training records;
• opening checks and corrective actions; and
• supplier notifications about formulation, labelling or safety changes.

For prepacked slush drinks and make-at-home concentrates, FSAI advises appropriate on-pack warnings consistent with its current advice. Retailers should not remove or obscure required food information and should escalate missing or inconsistent information to the supplier.

What if a child becomes unwell?

Potential adverse effects described by FSAI include headache, nausea, vomiting, dizziness and low blood sugar, with loss of consciousness possible in severe cases. Staff should follow the business’s emergency and incident procedure, help the customer obtain appropriate medical assistance and alert the responsible manager immediately.

Record the product, flavour, serving size, time of purchase, amount reportedly consumed, batch or supplier details, symptoms described and contact information where appropriate. Preserve relevant product, packaging, machine set-up and preparation records. Do not diagnose the cause or make assurances about recovery.

Assess whether the product may be unsafe, incorrectly prepared or inconsistent with its specification. Where there is reason to suspect unsafe food or a wider product issue, follow the business’s food-incident procedure and contact FSAI or the relevant competent authority promptly.

What should a multi-site operator standardise?

Head office should not assume that every site uses the same syrup, cup size or machine settings. Build a controlled list of approved products and map the warning and refill procedure to the actual formulation used at each location.

Standardise:

• approved product and supplier specifications;
• the exact Irish warning artwork and where it must be positioned;
• machine preparation and dilution instructions;
• cup sizes and refill rules;
• daily verification and exception escalation;
• the process for supplier formulation changes; and
• incident reporting and cross-site stock checks.

When guidance changes, record which locations were updated and which remain outstanding. Silence from a site is not evidence that its warning, stock and staff briefing are correct.

Practical operator checklist

• Confirm whether each slush product contains glycerol, glycerine or E 422.
• Keep the current product specification and preparation instructions.
• Display FSAI’s warning clearly and permanently at the point of sale.
• Check the notice before service and after cleaning, refilling or moving the machine.
• Avoid free or unlimited refills where children may consume the product.
• Train staff on the warning, refill rule and escalation route.
• Review promotions, cup sizes and self-service instructions.
• Record missing signs, unknown products and preparation errors as corrective actions.
• Recheck every control when a supplier changes the formulation.
• Monitor FSAI advice and any future change to additive limits or labelling requirements.
