Type and intensity of parasites in wastewater from the municipal swine slaughterhouses in the central region of Thailand
Abstract:
The swine slaughterhouse is an important place for pork production. Most
slaughterhouses lack wastewater management. If there is not a good and effective
waste material management system, the swine slaughterhouse will be a major place for
spreading pathogens especially parasites, to the environment. The objective of this
study was to detect the type and quantity of parasite and to determine an associations
between factors of swine slaughterhouses and the contamination of parasites in the
wastewater from municipal swine slaughterhouses. Wastewater samples were taken
from each of 41 municipal swine slaughterhouses in the central region of Thailand.
The samples were tested by modified formalin-detergent technique. Unsporulated
Eimeria and/or Isospora oocyst, Ascaris spp., Balantidiun coli, Trichuris spp,
Strongyloides spp., Rhabditiform larva , Adult Ascaris spp., Adult Trichuris spp. were
found in 36.6%, 34.1%, 19.5%, 12.2%, 4.9%, 4.9%, 4.9%, 2.4% of sample
respectively. The type of wastewater treatment modification system had a significante
association with the contamination of parasites in the wastewater from the municipal
swine slaughterhouses. There was also an association with cracks in concrete floors
with contaminate of parasite in the wastewater.
Wastewater treatment modification systems should be adjuster or new ones
should be built to conform to the regulations of the department of livestock
development. These systems and the concrete floors of the slaughterhouses should be
maintained in good condition to prevent the spread of parasites to the environment
