Caution!

Last year, I ate a bowl of salad with soy-sauce dressing. It was very delicious.

Next day, I had a lot of things to do, but I couldn't do anything because of nausea and a stomachache. I couldn't leave the toilet.

Fortunately, I didn't throw up, but I felt so bad. I thought the cause of

my sickness was the dressing. It was a month past its use-by-date!!

I didn't know that. I think soy-sauce which is a month past its use-by-date is

OK, but oil isn't.

Please be careful when you use any dressing.
