Note. The lines with bold lettering refer to the 3 samples with a L. monocytogenes concentration of >100 cfu/g.

^(∗): zero time, analysis of one of the three sample units on the day they reached the laboratory.

^(∗∗): 4^°C, analysis at the end of shelf-life at 4^°C storage conditions.

^(∗∗∗): 10 ^°C, analysis at the end of shelf-life at 10^°C storage conditions in the last third before final expiration.

^{(∗∗∗∗)}: packaging with bulging at the end of shelf- life with no unpleasant odour.

^{(∗∗∗∗∗)}: samples from the same company but from different batches.
