Owning Chametz on Pesach: Difference between revisions

* The Gra 443:11 writes that if someone has chametz of another Jew in your property you violate Baal Yiraeh and Baal Yimaseh. He proves it from Rashi Pesachim 5b. Peni Yehoshua there and 4a agrees. See Or Chadash 4a who disagrees and argues based on Rashi Pesachim 46b. Rav Soloveitchik in Mesorah v. 3 p. 7 answers this proof of the Or Chadash. The fnt. on Maharam Chalavah Pesachim 4a fnt. 26 cites also the Bet Meir 443, Torat Chaim 4a, and Tzlach 5b who hold like the Gra.

# Similarly, if someone has a deposit of another Jew's chametz in his property on Pesach he must get rid of it and there is a discussion if the one who has it deposited by would violate Baal Yiraeh and Baal Yimaseh.<ref>Bach 443:5 and Magen Avraham 443:5 state that the one who has the chametz deposited by him wouldn't violate Baal Yiraeh but the owner would violate Baal Yiraeh, while the Gra 443:11 disagrees. Meiri Pesachim 4a s.v. vkol implies that in fact neither the owner or the one who it is deposited by would violate Baal Yiraeh.</ref>

# A chametz mixture which do not have the ability to leaven other foods and is inedible to people is permitted to own and benefit from on Pesach.<ref>Shulchan Aruch O.C. 442:4 clarifies that a chametz mixture is permitted if it isn't human edible and can't be used to leaven other foods. [https://www.hebrewbooks.org/pdfpager.aspx?req=14336&pgnum=342 Chazon Ish OC 116:7] notes that the Rambam Chametz Umazah 4:12 clearly holds that the standard that chametz is forbidden unless it is inedible to dogs only applies to foods which are used to leaven other foods such as spoiled bread. However, other medicines or tanner's liquids which aren't used to leaven other foods are permitted as long as they human inedible. Mishna Brurah 442:12 seems not to distinguish. Dirshu 442:20 explains that the Mishna Brurah fundamentally agrees with the Chazon Ish and is only strict on something that can be used to leaven other foods and people wouldn't do it because it is disgusting.</ref> Therefore, using tropical fish food that has chametz as an ingredient may be owned on Pesach and may be fed to fish on Pesach since it is edible to people.<ref>[http://halachayomit.co.il/en/default.aspx?HalachaID=2470 Rav Yaakov Sasson on halachayomit.co.il] quotes Rav Ovadia Yosef and Or Letzion v. 3 p. 92 that it is permissible to have and use tropical fish food which chametz in it since it is human inedible.</ref> However, other pet foods such as dog, cat, and bird food potentially could be edible to people and therefore are forbidden if they contain chametz.<ref>[http://halachayomit.co.il/en/default.aspx?HalachaID=2470 Rav Yaakov Sasson on halachayomit.co.il] writes that dog, cat, and bird foods which chametz are forbidden since they could be human edible. Even though generally people would never eat them that is only because of convention and the fact that better foods are available. For example, Minchat Shlomo 1:17 proves that the standard of human edible doesn't depend on what most people would want to eat as the gemara considered urine to be human edible. [https://www.koltorah.org/halachah/chametz-mixtures-and-pet-food-a-bold-and-controversial-approach-by-rabbi-chaim-jachter Rabbi Chaim Jachter] quotes Rabbi Avihud Schwartz (Techumin v. 35 pp. 47-54) who in discussing the Israeli army dogs that the dog food is not human edible and would be permitted if it isn't majority chametz or used to leaven other foods. Rabbi Jachter concludes that the standard Orthodox halacha pronounced by the OU, Star-K, and CRC is that pet foods with chametz are an issue and should be replaced with kosher for passover alternatives.</ref>

#Is there is baal yiraeh on less than a kezayit? Maharam Chalavah 45a s.v. amar and Rabbenu Dovid 6b s.v. iylayma explicitly hold that there is a biblical violation of baal yiraeh on less than a kezayit like every other prohibition that is prohibited with less than the requisite measure (Yoma 74a). It is possible to argue that based on Rashi, Tosfot, and other rishonim on 45a baal yiraeh biblically does not apply to less than a kezayit though it isn't explicit in their conclusions. Taz 442:5, Magen Avraham 442:10 in understanding Shulchan Aruch O.C. 442:11 and Smak, Shagat Aryeh 81 hold that there's no biblical violation of baal yiraeh on less than a kezayit.
