Beware Leaven found in Matzoh products

One of our 360 Yahoo friend found some leaven in matzoh product here is what she wrote:

WARNING! Leven found in Matzoh products!

Shalom Sisters!

If you have ANY Matzoh products, check them for leavening.
I frond Sodium Bicarbonate (baking soda) in Matzo Ball Mixes.
BTW, it said "use for Passover on carton"! Shocker!
