However these zoonoses persist, especially in areas where poor sanitation, ineffective sewage treatment plants, irrigation with raw sewage/heavily contaminated surface water, free range or smallholder pig production and informal slaughter practices prevail. This is due to the enormous reproductive potential of Taenaeiid tapeworms where adults measuring 1-12m release one or more gravid proglottids (segments 0.5cm x 1-2cm sized) daily, each containing 50 000 to 80 000 eggs.(Schmidt 1986, Hyman 1951)
