Protocols adapted from Masangkay, et. al (2016) and Paller, et. al (2017) were utilized to effectively process the samples. Modified Ziehl-Neelsen staining was performed on the sediment samples. After which, microscopic analysis was executed to determine the presence of Cryptosporidium parvum from the samples. The pools were also subjected to profiling through questionnaire format, adopted from the survey by the CDC (2006). Out of six samples, all are negative from Cryptosporidium parvum oocysts. This is mainly due to the different sanitary practices in the maintenance of the establishments, which are qualified in the standards according to Sanitation Code of the Philippines (P.D. 856), and the pH and chlorine levels further confirmed through water analysis that affected the presence of the said parasite.
