Updated July 19, 2017

The general consensus between the North Dakota University, whatscookingamerican.com, and Virginia State University, is that after opening a container of yoghurt it will stay good for about two weeks as long as it's kept in the refrigerator. They do not recommend eating it after seven to 10 days.

About two weeks

The general consensus is that after opening a container of yoghurt it will stay good for about two weeks as long as it's kept in the refrigerator. North Dakota University and Virginia State University do not recommend eating it after seven to ten days.

Watch expiration dates

According to the Chobani Yogurt and Dannon Yogurt websites, yoghurt can be eaten past the sell by or the expiration date on the containers as long as you don't see any mould growing on it or smell sourness that often comes with spoiled dairy products.

Bottom line

The Chobani Yogurt website says, "if the yoghurt looks, smells, and tastes good, and there are no visible signs of mould, it's most likely OK to eat." If the yoghurt passes the smell and the mould test it should be good to eat.
