Can I still use my Worcestershire sauce? So we have this Lea&amp;Perrins Worcestershire Sauce from the past 6-7 years ago. And I would like to really know if it is still safe to consume?

I've done my research but I'm still not sure if I could consume it because I do not know how it actually tastes. 

It is kinda dusty on the top, but it was last opened years ago and it was just in our cabinet so i don't know if it is still safe to consume
Lea &amp; Perrins Worcestershire is shelf stable.  As long as it's been in the cupboard with the cap on, it is safe.  The flavor may have degraded, but it won't make you sick.
