Manischewitz spokesman David Rossi says there were delays getting a new oven working at a New Jersey plant. Because of that, the company didn't have enough time to produce its full line of matzo products for Passover.
But other companies are producing the bite-sized matzo crackers and some stores still have leftover boxes from last year.
Matzo is made without yeast. Eating unleavened bread is an essential part of Passover.
