There are numerous types of bacteria, diseases, viruses and parasites that are carried in canine feces.  The devastating effect of Roundworm is usually blindness to children and can be transmitted to adults also.  Roundworms can develop within a couple of weeks and can live from months to years on your property.  This is why a weekly service visit would be very beneficial to ensure protection against contamination and transmission to humans.  Maybe this is why many doctors have referred pregnant women and also employ our services themselves.
