1.2 Extension of shelf life

Any extension of shelf life greater than kill+4 days shall be subject to satisfactory documented shelf-life verification (sensory and microbiological evaluation) that shows that the extension of life does not, under worst case conditions, adversely affect product safety or quality. The microbiological limits shall not exceed the levels that will impact the quality and food safety of any finish products. 

NOTE: the UK has a derogation for the extension to the 6-day kill to mince.
