As you know my elderly father has difficulty eating matza and sometimes after eating and swallowing, he vomits it. How long does it have to be in his stomach until it is considered that he ate it? If he ate and then vomited, does he comply with the mitzva?
A. Horav Shlomo Miller Shlit’a maintains that as soon as it was swallowed, he has complied with the mitzva.
