bearded dragon parasites

Question
We are new to having a pet bearded dragon and I was wondering about risks of zoonosis.  I understand the top risk is with Salmonella and that therefor one must always be careful to wash the hands after handling a lizard and avoid cleaning water bowls, etc in the kitchen.  However, I wonder how careful do we need to be?  Hand washing is easy, but do we also need to disinfect every article of clothing or furniture a lizard has come in contact with?  Beside Salmonella, what is the risk of transmission of parasites, such as pinworm, hookworm, or coccidia?  I am also confused about the sources of intestinal parasites.  I have read that we should avoid feeding our beardies insects from the garden (ours is entirely pesticide free) because of the risk of parasites, yet I've also read that crickets are the major source of coccidia, yet they are the recommended food, aside from vegetables.  Could you please clarify these issues?  Thanks.

Hello Dan,

Those are good questions.  Do you have children?
Really to be honest, there is not that much of a risk of salmonella anymore than there is with raw chicken.  The same principles apply, just keep the hands washed when handling feces or cleaning up after their feces.  Just handling them, normally, you will not contract salmonella.
The water bowls for them, need to be kept clean 1-2 times per day, just in the case they go to the bathroom in the water which some will. No, you don't need to clean & disinfect every single thing that he comes in contact with to avoid salmonella.  Only if he goes potty on something, then, it needs to be cleaned.  Other than that, there is no salmonella risk.
The transmission of internal parasites for them, is usually pretty easily preventable.  The water bowls are breeding grounds for bacteria if they are not kept cleaned.  If they go to the bathroom in the water they can be drinking dirty feces contaminated water which will make them sick with  parasites.  
They do have normal, low levels of normal parasitic levels in their body of coccidia & pinworms so that is fine.  It is when it gets higher than what it should be is when it begins to cause problems.  Again, the only way we can contract worms from them is fecal to oral.  So, just wash the hands, & especially if you have kids, do not let them handle the feces without washing their hands.  Otherwise, yes, they can get worms.  That goes the same for dogs though as they can have worms too that we can contract also.
Hookworms are not a real common worm that they get but they can get them from time to time.  Those are bad & can cause alot of problems, as well.  
Crickets in the petstores are the worst culprits of disease because they don't keep them clean.  I would order from reputable places online, & or learn to breed your own so they are cleaner.  I have never had problems with crickets though.  
As far as letting them eat bugs from outside, it is questionable.  You never know where they insects have really come from or what they have come into contact with so I do not recommend feeding them bugs from outside.  If you have an organic garden, just wash everything well & that is fine to feed him.  
I hope that helps out alot.  Let me know if you have any other questions.  :-))
