most of the info I found says cooked meats are OK for 3-4 days, assuming they were refrigerated in a timely manner after the meal.

If you have too much left over you can freeze portions for later use.

At 6 days out I guess it depends on you & if you have a sensitive system or not.

If you have a dog or cat???
I often cook up/boil questionable leftovers again and pour the broth and spare meat pieces over their food.
