Cryptosporidium, Giardia and Cyclospora,
Did you know that bacteria are not the only cause food poisoning outbreaks. There are other microorganims out here that can produce similar symptoms. These are the protozoan pathogens and they include Giardia, Cryptosporidium and Cyclospora. All have been associated with several foodborne outbreaks.
Protozoan are single-celled, microscopic animals that reproduce in the intestinal tract of the host (eg humans and animals). As part of their life cycle, they produce eggs (cyst or oocyst), which is part of their reproductive cycle and helps them to spread and reproduce. These eggs are excreted in the faeces and are extremely infectious through water or food. With the majority being waterborne, they are found in sewage, lakes and ponds. Although rare, swimming pools and possibly the drinking water could a source. The only way to find if they are present is to test for them using water microbiology laboratory.
If you are infected with these protozoans (intestinal tract), it causes the following symptoms: Watery diarrhoea, fever, muscle aches, abdominal cramps, nausea and vomiting. Symptoms can last for months.
