Heinz Salad Cream (Dressing) Original, 14.9-Ounce Squeeze Bottle (Pack of 6)

Seller- Please can you advise of the sell by date please- generally speaking (I know different batches will have different dates)?

I used this for months in the UK. What is the shelf life if it is refrigerated?

Like others I find the sell by date confusing, is it month, day, year or day, month, year? Why don’t companies use day numbers exceeding 12.

Can this be used on spotted duck?
