Tomb of Tana Hakadosh Rabbi Nachum Ish Gamzu
Rabbi Nachum Ish Gamzu was one of the first Tannaim (sages of the Mishnah era) and teacher of Rabbi Akiva
Hello, rabbi
I wanted to ask if the disposable aluminum trays bought in stores need to be immersed in a mikveh for utensils?
I heard that this is Rabbi Ovadia Yosef’s opinion on this, is it true?
Thank you
Hello and welcome
Rabbinic authorities (poskim) disagree on the issue of disposable metal utensils, such as aluminum trays, disposable grills, etc., regarding whether they require ritual immersion.
The opinion of Igrot Moshe, Minchat Yitzhak, and also Or Lezion, among others, is that disposable utensils do not need immersion, as they do not have the status of utensils since they are not intended for repeated use.
However, the opinion of Rav Ovadia Yosef zt”l, Shvut Yaakov, Tzitz Eliezer, and others is that even disposable metal utensils require immersion, as they are suitable for repeated use by themselves.
Therefore, it is important that buyers of disposable forms check if they are produced by a company in Israel and not imported from abroad.
Sincerely
PLEASE NOTE*
Attention: You should not learn from one case to another, each case must be analyzed individually. Generally speaking, it's always best to have contact with a Rabbi in person, not just virtual contact. Note that where there is a local Rabbi("Mara Deatra"), one should ask him. The answers are under the responsibility of the rabbi who responded, and not under the responsibility of the website and/or the Head of the Institution.
