I got on the Pepperidge Farms website for more info. Well, thank you Pep Farms for providing no information on your website! It literally just says "...and they're gluten-free" at the end of a product description. They don't even list the ingredients for the product - that just seems shady to me! They also don't provide any statement on how they deal with allergies and special dietary needs. There's also no way to actually call them, you have to send one of those annoying message-things and wait to hear back from them and then they don't even answer your question.
So for now, I'd only recommend these little fishies to people who are choosing to not eat gluten or have a sensitivity/intolerance. Since I have Celiac Disease, though, and I can't verify if these are safely free of gluten then I'll just have to wait until I can find out more! Hoping to have good news about these little fishies soon! If you have any info or see something on their website that I missed let me know!
