I dont know how safe this place is but I had a pizza 2 Times during my stay in Corralejo and felt ok after my visits. Pizza is super thin, delicious, really good sauce. I had one with ham and next with jamo serrano and tomatoes. 2nd is my preferred one. They said that they can preparw almost everything gluten free from the menu. I can recommend you this place, and that was also the only GF pizza I have found in corralejo. In others from google maps they were saying they do not have GF pizza.
