Israeli farmers have begun to prepare cows for the Passover holiday, set to begin in just two weeks. During the holiday, Jews do not eat any leavened products, nor do they feed leavened products to their animals.
Farmers begin to introduce the cows to a non-leavened diet in stages. The Passover diet includes legumes, corn, and sesame seeds. In addition, milk produced for the holiday undergoes extra filtration to make sure it doesn’t contain any leavened bits.
