The 25-g aliquots were placed in Stomacher® 400 filter bags containing 225 ml of buffered peptone water (HiMedia Laboratories, Mumbai, India). The samples and diluent were mixed in Stomacher® 400 for 60 seconds.
The study found that there was no difference for the recovery of C. jejuni from fresh, refrigerated or frozen samples after selective enrichment, showing that this microorganism can survive under the tested storage conditions.
