Re-Giardiasis,
According to my doc,this parasite is mainly water borne,i.e swimming pools,the sea,drinking water etc.
Other areas such as uncooked food i.e salads fruit that may have been washed in local water can be a problem.
The parasite lives in the intestine and after a bowel movement can survive for long periods.
Apparently the bug can be transferred by accidently or not as the case may be swallowing soil,food,water or touching surfaces that have come into contact with the faeces of infected animals or people,so dont use your hands to eat, and wash and peel fruit etc.
Ash the rep told me the glasses are washed by hand not by machine so that could possibly be a source,also the ice and lemon in drinks is served by hand this could also be a possible source of transfer.
I my self did not use the pool and was ill for a week so I dont think its that.
Also the strength of the anti biotics used to combat this parasite mean you should not drink alcohol or you can get rearly sick.
I must stop being such a gloom merchent,but if you get this its horrible so be careful..............
