I ate all sorts of things too - if you're unsure next time, just microwave your chicken super hot first. I think all Australian cheese has to be pasteurised first anyway, so if you eat that fresh it might be alright...I think the issue is, that some things are really ambiguous - some foods are okay fresh, but not as safe if they've been left out, or stored, and it's just easier to create a blanket rule about that food saying to avoid it. Soft serve, for example, is considered risky because we can't guarantee that the soft serve machine has been properly cleaned and maintained. The actual food itself isn't bad.

I think I read somewhere that you're more likely to be hit by a car than contract listeria? Not sure of my source there. So...I guess just be aware of what's healthy to eat, go get normal ice-cream instead of soft serve...and be careful when crossing the road!

No point beating yourself up if you do eat something not recommended though. What's done is done.
It might be worth avoiding the borderline foods just for your peace of mind though.
