I used to work as a Pharmacy Technician at many different pharmacies including CVS. The prescription pills you take everyday most likely have fecal and urine matter and other bacteria on it because while counting the pills, they often roll and fall on the floor. Since most medications are expensive we just pick it back up off the floor and put it in your medication vial.
I've seen pharmacists and technicians accidentally step on the pills with their dirty shoes and they just pick them back up and put it in the vial and give it to a customer.
