The Mickey's Ice Cream Bar is a pre-packaged treat manufactured by Nestle. It is free from fish and shellfish.

This meal contains milk, soy and eggs.

We do not consider this meal gluten/wheat, peanut or tree nut-friendly due to being produced in a facility that also processes wheat and peanuts/tree nuts.

*Note: People have reported experiencing peanut/tree nut reactions allergic reactions to the Mickey's Ice Cream Bars.
