I used an expired cooking oil due to oversight

Latte bought a bottle of OKI Brand canola cooking oil (2 Kg pack) last year. The expiry dated was September 2008.

Only after I last used the cooking oil on 2nd April 2009 to cook fish vegetable soup for BB and GG, she told me that the cooking oil was expired in last September!

It was fortunate that there was no food poisoning for using the expired cooking oil. It might be due to the very little quantity I used for cooking soup.

The lesson learned: Always monitor the expiry date of processed food if we have to use it. Of course, if there is a choice I would not use cooking oil at all.
