I purchased a container of Co-ops bleach yesterday.
Printed on the label was "Suitable for vegans"

Many years ago I visited the USA and bought a Beef Sandwich...........on the label it said , ' suitable for Vegetarians '

Also

A Cheddar Cheese sandwich that had a label..........' No milk products used in the manufacturer of this product '

I once bought a tin of mackerel with the allergy warning 'Contains Fish'.
