Dehydrated meals + customs

hey all! I was planning on packing my own dehydrated meals due to severe food allergies - I make + dehydrated my own meals and didn’t even think about potential issues getting them through customs til recently. We are flying from U.S to Geneva

Does anyone have experience with bringing pre-made (homemade) backpacking meals through customs? I understand that store bought ones are typically fine, but would like to avoid those as I have ~2 weeks of homemade meals that I know are safe to eat already!

Thanks for the advice :) would hate to lose it all.
