Salam Alaikum. Thank you for your concerns as a Muslim about Halal food in the Maldives.
I have been to Paradise Island a couple of times and I've heard that the Resort does not import pork for their cuisines. And knowing that I am a Muslim they told me that the food is halal and to be only concerned about alcohol. I hope you can come to Maldives and have a nice time, InshaAllah.
