Can you simmer turkey carcass for 4 days?

It is not advisable to simmer a turkey carcass for multiple days. There is a potential for safety risks, including bacterial growth and spoilage. Turkey meat should not be exposed to temperatures between 40°F and 140°F for an extended period of time, particularly over several days. If you wish to make turkey stock or broth, follow recommended food safety guidelines by simmering the carcass for several hours instead of multiple days.
