“As per the defination of “”Use by date”” in FSS (Packaging & Labelling) Regulation, 2011
“Use – by date” or “Recommended last consumption date” or “Expiry date” means the date which signifies the end of the estimated period under any stated storage conditions, after which the food probably will not have the quality and safety attributes normally expected by the consumers and the food shall not be sold;
Thus, you shall not use the product beyond use by date.
“Best before” means the date which signifies the end of the period under any stated storage conditions during which the food shall remain fully marketable and shall retain any specific qualities for which tacit or express claims have been made and beyond that date, the food may still be perfectly safe to consume, though its quality may
have diminished. However the food shall not be sold if at any stage the product becomes unsafe.
Thus, you may use the food product beyond best before date. However the food shall not be used if at any stage the product becomes unsafe.”
