Challenge tests and shelf-life studies with Listeria monocytogenes

For several weeks now, there has been a new version of the "EUR2 Lm TECHNICAL GUIDANCE DOCUMENT on challenge tests and durability studies for assessing shelf-life of ready-to-eat foods related to Listeria monocytogenes Version 4 of 1 July 2021."

This version contains some relevant changes compared to the previous edition.

These include, for example:

• It is generally required to test at least three batches. This corresponds to the implementation of at least three batches or challenge tests with Listeria monocytogenes.
• The recommended temperature profile for storing food during the challenge test has been changed from +12°C to +10°C in the last third.
