There is a real possibility that they were in compliance with both Islamic and Jewish dietary rules all along and all they did was revise the label
On the other hand I found about a year ago that "Kosher for Passover" means that there's NO wheat, barley or rye gluten in a product.
There's rarely any "Kosher for Passover" marked foods on the market tough so it's nothing you can count on.
If they were in compliance with Kashrut, the label has a small “K”in a circle on the label. If the product is “Pareve” meaning that it contains neither milk nor meat, a “P” in a circle appears. If the product is “Kosher for Passover” (contains no leavening) THAT will appear on the label. It is up to the Observant Kosher Jewish person to look at the labels and READ them prior to buying the product, based on THEIR personal beliefs. I have No problem with that.
But when a Company announces that they will now be “halal” or use Sea Salt merely to appease politically a correct green agenda-driven propaganda machine, I have to draw the line.
