Ingredients and suppliers
Product specifications, recipe information, supplier changes, labels and the process used when information is incomplete.
For food-service organisations
GCSI helps restaurants understand their current practices, identify priority gaps, educate employees and communicate honestly with people who need medically necessary gluten-free food.
A baseline, not a judgement
The initial assessment is designed to make current practices visible. It identifies where controls are already working, where evidence is missing and where manageable improvements can reduce uncertainty.
A lower result in one area does not label a restaurant as irresponsible. It shows that the current evidence or process does not yet demonstrate the expected practice and connects that finding to a practical next step.
What GCSI examines
The developing GCSI Index follows the dining journey and the responsibilities of managers, kitchen teams, front-of-house employees and suppliers.
Product specifications, recipe information, supplier changes, labels and the process used when information is incomplete.
Storage, preparation, utensils, surfaces, cooking water, fryers, grills, cleaning, handwashing and order identification.
What employees know, how uncertainty is escalated and how information moves between the diner, service team and kitchen.
Written procedures, onboarding, refresher training, incident handling, internal checks, reassessment and improvement records.
Improvement pathway
The service is structured as an improvement cycle rather than a one-time badge.
What your team receives
Transparent communication
GCSI helps restaurants avoid both unsupported reassurance and unnecessarily defensive communication. Public wording should explain the assessment scope, evidence level, date and limitations.
“Staff-training records and ingredient procedures were reviewed. Shared-fryer controls were not demonstrated.”
“Completely safe,” “zero risk,” “celiac-proof” or other claims that no assessment can responsibly guarantee.
Employees should pause, check and explain the limitation rather than guess or provide contradictory reassurance.
Commercial independence
Assessment, training, reassessment and platform services require resources. Payment never determines the evidence level, score or public status.
Relevant commercial relationships, assessment scope, methodology version and conflicts of interest must remain visible. Restaurants also receive a correction and appeal pathway when information is incomplete or inaccurate.
For independent restaurants and larger organisations
The framework can support an individual restaurant, hotel, café, caterer or multi-location group. Larger programmes may include central dashboards, common procedures, train-the-trainer models and site-level reassessment.
Vienna pilot
The pilot will examine feasibility, staff learning, documentation burden, implementation barriers and how clearly evidence can be communicated to diners.
