⚠️ Risks & cross-contamination
- The facility is not dedicated gluten-free. Cross-contamination risk remains a factor in any non-dedicated kitchen.
- While staff commonly practice glove changes, separate prep areas, and foil-wrapping for GF sandwiches, there are documented instances where cross-contact could occur, especially if toasted or prepared alongside gluten-containing items.
- Availability of GF bread can be variable; there are reports of temporary shortages that could affect safe options on a given visit.
