I just had a reminder of what bacteria can lurk in food. Up all night with a terrible stomach and feeling quite weak today, which happens to be my birthday so celebrations around eating cancelled. I roasted a chicken yesterday and I'm pretty sure some campylobacter on the raw chicken must have transferred to something as I was preparing it, and then I must have ingested it somehow.
A lesson that it's not just how long you cook food, it's what raw food touches on its way to your table and how that can spread round your kitchen in an invisible way.
