This study directs to Cyclospora, Microsporidia and Cryptosporidium three parasitic protozoa may be spread in food or water,
even if are not considered as huge a risk to food production, owing to the fact that in cold and humid conditions, they may
stay alive for months, control of them is important and following of consumption of contaminated drinking water or foods that
have not received heat treatment, some outbreaks may appear. In this study we assessed the frequency of the two parasites in
fecal samples submitted to the Central Parasitology laboratory of Tabriz, Iran. From 2009 to 2010, 1825 fecal samples submitted
to the Central Parasitology laboratory of Tabriz were assessed by conventional methods of Light microscopy, Formalin-ether
concentration technique, staining technique and PCR method. The frequency of Cryptosporidium was 0. 0%, 15%, 3% and 2%
and Microsporidia were 0.0%, 3%, 1% and 0% by methods of microscopy, formalin-ether concentration, staining and PCR,
respectively. Cyclospora was not found in all the stool samples examined. The frequencies of these three protozoa in our study
were less than our expectations. Lack of infection with Cyclospora can be good news for local health care providers. More
investigations especially in at risk populations is needed for health policy making.
