If a fly lands on my grill and dies while I am grilling meat. What is the status of my food? What is the status of my grill ?
All you have to do is get rid of the fly, and make sure nothing is left of the actual fly. All the food, and the grill are permitted to use, and you do not have to kasher the grill. The reason for this is, since a fly is disgusting, and chazal said that it tastes disgusting, it is considered “nosain taam lefgam”, therefore it is permitted. Note: there is an opinion brought in the Rama that one should wait 24 hours before using the utensil that absorbed such taste, however when the absorbed taste is from something so disgusting as a fly, there is no need to even wait the 24 hours.
