Please don’t attack me for not providing a sources, I’m not as learned as many here.
If i say something halachic on a forum, then i definitely have heard it from somebody who is clearly a talmid chochom, and baki b’ halacha. In this case i can’t remember who it was, but it made a roshem. Generally, i am more of a skeptic.
Maybe everyone else knows this , but
I have only recently learned that Yashan in Eretz Yisrael is not a chumra.
Outside of EY, it is still considered a chumra to refrain from chadash, because there are significant chilukei dayos haposkim of whether it applies. I don’t think there’s much disagreement that eating only yashan is REQUIRED in Eretz Yisrael. That applies to food that grew there, AND [If understood this correctly] also to food that you bring in, if you’re going to eat it there! (The sandwich you didn’t end up eating on the plane). You do have the option of holding on to your (crackers?) and eat them once you have left the holy Land. And… food that is chodosh, that grew in E.Y. has no special requirement to be avoided outside E.Y. (unless of course you are following the chumra of eating only yoshon outside of E.Y.)
If you are frum, you are quite likely to have learned that there are special halachos that apply to food in E.Y. As a Torah observant jew, if you go to E.Y., it is up to you to prepare, and learn how to follow the halachos that pertain only to there. You should find about them from the outset, or immediately upon arriving there.(You probably DO make sure to check the weather forecast before you go, not leaving it up to chance!). It shouldn’t be up to the OU to notify you that INSIDE E.Y., you must eat only yoshon, no matter where it comes from. For such issues, kashrus is highly dependent on how and where a product is consumed.
Regarding milk powder, Rav Moshe Feinstein’s psak about chalav yisroel affects how we look at the issue. For those not in the U.S.A., it is a far different matter. There apparently is strong reason to conclude that although chalav yisroel is non-negotiable (outside of the U.S., where Reb Moshe’s psak has any significance at all), milk powder as a substance is changed so drastically in the process, that for some reason it no longer requires to be of a chalav yisroel source for some reason – I don’t remember the details.
