There are no hard and fast rules about the length of time corned beef will keep. That will depend upon several factors including
# the recipe/formulation # the packaging used # the handling of the corned beef from production through distribution to the store and by the consumer
# the actual conditions of storage - especially temperature and temperature fluctuations
Most of the information we have available are just guidelines. So use those and a bit of good sense.
