Sickness bug hit our household this week so decided on a easy quick lasagna ready meal from Tesco that your just microwave. It wasn’t until I had ate it that I realised our microwave setting was on defrost and not on high. It was definitely warm but I had left it in the microwave for about 5 mins after it finished as I was just pottering about so it didn’t occurs to me that it wasn’t boiling hot. So now I’m worrying about listeria. Is it common in ready meals? Anyone one has something similar and been fine? 31 weeks pregnant and not sure why the anxiety kicks up a notch in the last trimester
