A house guest cooked frozen vegetables in a milk pot (no onions), but then strained them in a plastic meat strainer. IS that strainer now treif? Do we have to throw it out?
No, the strainer is still kosher. The reason is because we can assume (unless we know otherwise) that the pot was not used within 24 hrs. prior to when the vegetables were cooked. therefore it will not be able to make the strainer trief. Of course, this is only if there wasn’t any milk in the pot.
