If turkey smells sour but has been refridgerated is it safe to eat?

No, it is not safe to eat turkey if it smells sour, even if it has been refrigerated. Sour smell is an indicator of spoilage and the growth of bacteria that can cause foodborne illness. Eating spoiled turkey can lead to symptoms such as nausea, vomiting, diarrhea, abdominal pain, and fever. Therefore, it is important to discard any turkey that has an off smell or other signs of spoilage.
