When he first saw a map of malaria's range, Mann says it was as if the scales had fallen from my eyes. That range extends almost precisely to the Mason-Dixon Line, along which the American Civil War broke out in 1861, between the slave-holding states of the South and the Union soldiers of the North.
Opened yogurt will typically stay at peak quality for 5 to 7 days after opening, but will generally remain safe to consume for at least 1 to 2 weeks after the sell by date on the package, provided it has been properly stored- discard entire package if any sign of mold appears.
It should be OK for up to a week past the sell-by date, if properly stored. While the National Dairy Council recommends a one-week refrigerated shelf life for yogurt, both Dannon and Stonyfield Farm imply a much longer life. Both clearly state the stamped date is not the date that the yogurt will expire or go bad.. It's more of an optimum eating period. As long as yogurt is properly refrigerated and it looks, smells and tastes good and there are no visible signs of mold or discoloration, the yogurt remains safe to eat.
