Please excuse my ignorance about nut and peanut allergies. I'm after some advice.
I work in a setting serving food to children. One of these children has a peanut allergy. The reaction is hives-like all over his face and body, rather than anaphylaxis. An anti-histamine is kept on-site.
When I am checking food ingredients lists if I see the unhelpful cover all phrase 'may contain nuts/made in a factory which handles nuts' I have been presuming this covers peanuts too. However a colleague started saying something about treenuts? In this context what is the difference between peanuts/nuts/treenuts? I feel like I've not ever read 'may contain peanuts'. Are packets ever that specific? Is there anything else I need to look out for on the bold allergens?
If someone with experience could just explain what I need to look out for when reading packets I would appreciate it. I should add that my employer has not given me training on this
as they presume we will all just pick it up. I know, I know. But that's a separate thread 
Cheers.
