I am looking for advice regarding staph aureus. I work for a low care vegetable processing company. We have been hand swabbing for staph aureus for the last 12 months. I have only recently had a positive result on one of our production staff. We have re-swabbed him and it came back positive again. I believe he could be a carrier. The result was <20. Apart from retraining on personal hygiene, is there any other corrective action I could put in to place?
