Recovery of putative taeniid eggs from silt in water associated with an outbreak of bovine cysticercosis.

Degenerate taeniid-like eggs consistent with Taenia saginata were recovered from sediment in the water supply of a beef feedlot under quarantine for Cysticercus bovis. Nine degenerate eggs in total were recovered from 482 modified flotation assays. Flotation controls of sediment spiked with known numbers of T. saginata eggs had poor egg recoveries, supporting the need for more sensitive assays for environmental samples.
