We appreciate your interest in our fruit snacks. Welch’s fruit snacks are produced in the same facility as dairy and peanut products. They are not produced on the same production line, but in the same facility. As always, we would not recommend the fruit snacks to those with sensitivities to dairy and peanut products. We suggest consulting your doctor before using the fruit snacks.
We hope this information is helpful to your search.
