Abstract EN
The present study was conducted to investigate the efficacy of sodium dich-loroisocyanurate (NaDCC) on the infective stages of common food-borne intestinal protozoa; Entamoeba histolytica(E.
histolytica), Giardia lamblia(G.
lamblia), Cryptosporidium, Cyclospora and Micro sporidia; beside its effect on raw green vegetables and fruits.
Parasites, isolated from stool of patients with diarrhea or dysentery, were exposed to NaDCC solution(lg/1) for one and two hours.
Disinfection effect of NaDCC was assessed by in-vitro viability, using trypan blue stain, and infectivity bioassay in laboratory animals as indicated by fecal and intestinal parasitic counts.
Raw vegetables and fruits were dipped in NaDCC solution in the same concentration and exposure time as used for treatment of the parasites.
Results revealed statistically significant reductions in viability and infectivity of all examined parasites indicating their susceptibility to NaDCC.
Relative variations in susceptibility were revealed; E.
histolytica and G lamblia were most susceptible(100% reduction) followed by Microspo-ridia then Cryptospridium and Cyclospora.
NaDCC did not affect the consistency, color, taste or flavor of raw green vegetables and fruits.
The proved efficacy of NaDCC, in cheap and convenient dry tablet form, makes it a promising tool in decontaminating raw vegetables and fruits from food-borne protozoan parasites at household and restaurant levels as well as in catering and fresh produce industry.
It is also recommended for disinfection of food preparation surfaces and equipment.
