Due to technical advances in materials, the expiration dates for cans and trays produced after March 31, 2004 will be two years from the date of manufacture.
Here is an example of the coding:
First Line: BEST BY MM DD YY
Second Line: Contains manufacturing information (i.e., plant, line and time)
MM = Month of Production
DD = Day of Production
YY = Year of Production + 2 Years
For example, a can manufactured on May 31, 2011 would be coded: BEST BY 05 31 13 (MAY 31, 2013).
