Yes I'm very careful...and I know the difference between 'use by''..and 'best before''...
I got shellfish food poisoning years ago after eating at a pub restaurant , I was so ill the doctor had to come to my home and give me intravenous antibiotics..
I have never taken a chance with food since then..
When my DD was small I worked in 2 major supermarkets in the uk part-time, and I know how date labels are changed , so I will never use poultry, fish, shellfish, or chicken within 2 days of their 'use by'' date .. nor deli meats...
I'm very careful to chill left over rice immediately before keeping it in the fridge and use within 24 hours or throw it out...
