Many food packets have expiry dates on them what happens to the food after this adte

Answer 1

Well everything that is manufactured have a expiry date..
For example, the bread have expiry date of usually 3-4 days after them they expired means we cannot eat them.. In fact u can see after that particular date there is dark bluish-green thing on the surface of it that is fungus and may cause u food poisoning..

The main aim is that after expiry dates the nature of that food starts changing and may get worse day by day..
