So you are fuming that you daughter was crouching outside her tent. A ten year old. And you automatically assume its food poisoning because it was on a camp site and there were raw chickens and basic facilities. Therefore its the leaders fault. Judge, jury and execution. You are ready to go in all guns blazing rather than take 5 to think that your precious daughter might be also be being a massive princess and drama queen. Talking to them in a few days when you've calmed down and got some perspective is a very good idea.
She's 10. If she really was that bad she was perfectly capable of stressing the point to leaders. What would she do if she was really ill? Instead it just sounds like exaggeration and whinging. Nothing particularly serious and certainly not worth ringing her parents and worrying them unnecessarily if its a matter of hours before she was due to go home anyway. Its not a trip to A&E here.
Secondly I'd like to ask what you think camping involves. No running water? God forbid!!! That's third world insanitary conditions unsuitable for all children. You have to walk further than 10 foot to the toilets. Won't someone think of all the children who died with their outside loos.
Frankly if you are not prepared to let your ten year old handle raw chicken even at home and haven't taught her hygiene (not your hysteria with gloves) then don't send her on camp for other people to have to baby sit. The point of camp is to get kids doing things, especially things they wouldn't do at home. The fact that you have this level of hysteria over chicken which means you wash chicken yourself in this way, screams more about you than what the guides may or may not have done at camp and whether your daughter has food poisoning or not. I suggest that you may be passing on your fears to your daughter...
Incidentally, running water isn't necessary much better than clean standing water - bacteria end up on the tap that every one touches. Funnily enough the places with the most bacteria in the house are not the places you'd expect like the toilet.
I swear to god, that some parents are determined to complain about something and expect their children to be pampered on camps rather than expecting their children to take a certain share of responsibility. Ruining it for everyone in the process because leaders get feed up of all the shit that comes with giving up their spare time for others to have a experience. Its up to parent and kids to take on some of the responsibility and understand there is a certain level of manageable and acceptable risk and that all risks can not be eliminated in life.
All I can say is thank fuck she's not a Scout at DH's troop or you'd have kittens. They've cooked over open fires and done camping without tents in December. And they use knives. And throw axes. (and yep there is a risk assessment for all of the above). Yes 10 year olds. Yes girls.
Second thoughts. It'd probably do her the world of good.
