Chametz After Pesach: Laws, Prohibitions and Practical Guidance

A Jew who left chametz in his possession during Passover:

• Has neglected the positive commandment of “removing chametz.”

• Has transgressed the prohibition of “no chametz shall be seen in your possession.”

Because of this, the Sages imposed a penalty and forbade chametz that remained in a person’s possession during Passover. This law is known as “chametz she’avar alav haPesach” — chametz that remained under Jewish ownership and was not sold is prohibited by rabbinic decree.

Chametz that is forbidden under this law may not be eaten or benefited from, whether by the owner or by others. The prohibition is rabbinic.

When There Is Doubt

Since the prohibition of chametz that remained over Passover is rabbinic, when there is uncertainty about whether the chametz was sold, one may be lenient, as is generally the case with rabbinic doubts. In such situations the chametz may be permitted — of course, only after consulting a qualified halachic authority.

When a Person Was Prevented or Forgot to Sell Their Chametz

• A person who was unable to annul or sell their chametz still has chametz that is rabbinically forbidden for both eating and benefit.

• However, if a person annulled their chametz but, due to circumstances beyond their control or by mistake, did not sell it, some authorities permit the chametz while others forbid it. In cases of financial loss, there are grounds to be lenient — yet one should not permit it for oneself without consulting Torah scholars.

• Even someone who annulled their chametz may not keep it in their possession during Passover; it must be sold according to halacha. If it remained in their possession without being sold, it becomes rabbinically forbidden.

Buying Chametz From Stores After Passover

• One should not purchase chametz products or foods containing chametz from a store that did not perform a proper chametz sale for Passover. It is advisable to request to see the official certificate issued by the Rabbinate confirming that the store’s chametz was sold.

• Anyone who knows of chametz that remained in Jewish ownership over Passover should inform others, in order to prevent them from inadvertently violating a rabbinic prohibition.

Eating Chametz That Remained Over Passover

One must be careful when visiting homes that do not observe Torah and mitzvot, where food or drinks made from chametz known to have remained in Jewish ownership during Passover — such as cookies, beer, or whisky, may be served. These foods may not be eaten because of the law of chametz that remained over Passover.

Stolen Chametz

If someone stole chametz before Passover and it remained in their possession during the holiday, and afterward they repent and wish to return it, that chametz is forbidden for benefit to the person from whom it was stolen.

Deriving Benefit From Chametz After Passover

Some authorities hold that chametz which remained over Passover is forbidden even to smell, if it gives off a noticeable fragrance.
