Kosher Caper! Is Your Matzah Really Safe for Passover?

JERUSALEM (CBS/AP) Is your matzah kosher for Passover?

Israel's Chief Rabbinate is warning Israeli citizens to be on the lookout for pirate matzah.

Just a week before the start of the holiday of Passover, Israeli police raided a warehouse containing a 7-ton stockpile of matzah with fake kosher certificates.

Matzah is flat, unleavened bread Jews eat during the weeklong holiday instead of regular bread.

Israel's Chief Rabbinate published photos Wednesday of the matzah packages, warning shoppers not to buy them. The rabbinate suspects that non-kosher flour was used to make the matzah.

"I can't believe that someone would do something like that," said Roy Wolf, manager of a leading matzah factory in Israel, after receiving calls from concerned customers.

Most Israeli Jews do not eat bread during Passover.
