Shelled Egg, Peeled Onion, or Peeled Garlic Clove Left Overnight
Several Biblical injunctions are derived from the warning to “beware for
your souls,” including the Biblical prohibition of placing oneself in any
type of life-threatening situation, e.g., walking dangerously near the
edge of a roof, exposing oneself to a disease, etc. In addition to such
obviously dangerous acts, our Sages warned against other dangers which are
not understood today, such as the well-known injunction against eating meat
and fish together. Although we cannot define the resultant danger in terms
of medical science, we accept and adhere faithfully to our Sages’ warning
that eating fish and meat together is a danger.
Another practice involving food which our Sages considered dangerous is
eating a shelled egg, peeled onion, or peeled garlic clove that was left
overnight. Although this practice is less widespread than the universally
accepted restriction against eating meat and fish together, the Talmud
maintains that a ruach ra'ah, literally a “bad spirit” or a “spirit of
impurity,” rests upon these three foods when peeled and left overnight,
similar to the “spirit of impurity” that rests on one's hands during
nighttime sleep. One who eats these foods after they were left overnight,
states the Talmud, endangers his life. Moreover, he will be judged by the
Heavenly Court as a person who took his own life. In view of the
severity of both the offense and the punishment, it is difficult to
understand why certain communities do not comply with this restriction. How
can they ignore such frightening consequences?
There is a basic difference, however, between the two prohibitions mentioned
above. The prohibition against eating meat and fish together is quoted by
the Shulchan Aruch as practical Halachah. All Jews—without exception—are
obligated to follow the rulings of the Shulchan Aruch, whether
scientifically understood or not. The prohibition against eating the three
peeled foods, however, is omitted by many of the Rishonim and the
Shulchan Aruch, probably because they held that the particular “spirit of
impurity” in question was no longer prevalent in their times. Thus, in
many communities this practice is not followed, and, indeed, many people
have never heard of it.
But in many other communities the practice is in force, to one degree or
another. While omitted by the Shulchan Aruch, the warning against eating
these three peeled foods is cited by some Rishonim, and recorded as
practical Halachah by several of the later authorities, among them the Peri
Chadash, Shulchan Aruch ha-Rav, Aruch ha-Shulchan and Ben Ish Chai.
Must everyone observe this prohibition?
Whoever comes from a family that adheres strictly to this custom should
definitely continue to do so, since it has a Talmudic source and is surely
not less valid than any other well-founded custom.
The poskim differ as to whether or not one who never followed this practice
is required to adopt it. Some rule that the practice is mandatory,
others recommend adopting it, while others do not require following it
The prohibition applies even when the peeled food items were wrapped,
sealed, and stored in a closed pot or container, or were placed in a
refrigerator. It also makes no difference whether or not the peeled
items were whole, cut up into large or small pieces, crushed or diced.
The prohibition applies only when...
- The entire egg, onion, or garlic clove was peeled. If even a
minuscule part of it was left unpeeled, or even if the root hairs on top of
the onion or garlic remain, the food is not considered to be "peeled" and
the prohibition does not apply.
- The egg, onion, or garlic clove was kept separate from any other food.
It is permitted, however, to mix them together with other ingredients such
as vegetables, tuna fish, vinegar, oil or mayonnaise, and leave them
overnight. Even adding a large amount of salt or sugar to the peeled
food items is sufficient to permit them to be left overnight.
- The egg, onion, or garlic clove was peeled with the intent of using it
immediately and it was then left overnight, or if it was peeled in order to
be used the next day. If, however, it was shelled or peeled with the express
intent of being frozen and used at a later date (as many large companies or
bakeries do), it is permitted.
- Dried egg, onion or garlic powder does not fall into the category of
"shelled" and is permitted.
- The egg, onion, or garlic clove is uncooked. When it is cooked,
roasted, or fried, several poskim hold that it may be left overnight.
- The egg, onion or garlic is left the entire night. If it is left for
only part of the night, it is permitted.
B'diavad, if these items were shelled or peeled and left overnight, what
can be done?
- Some poskim hold that b'diavad, one does not have to be stringent
and the peeled foods should not be thrown away. Many other poskim,
however, hold that even b'diavad these items should not be eaten.
- Some poskim hold that cooking or soaking the peeled items in vinegar
removes the "spirit of impurity" from them and they may then be eaten.
Other poskim do not mention this leniency.
- Washing the peeled foods does not alter their status—they still may not
