Q. When my father was hospitalized, his care giver stayed at his home for weeks. There is a security camera installed inside the kitchen. Do we have to be choshed for the kashrus of the utensils and food left?
A. Horav Shlomo Miller's Shlit”a opinion is that since the care giver was aware that the attention of the family was focused on the patient at the hospital and probably little if any consideration was given to the home kashrus situation, on the onset the utensils that could have been reasonably used, should be kashered and the unsealed food given to the care giver or other Gentile.
Although recording cameras are of great help in Kashrus and similar situations, they only help if the observed are aware that they are being monitored, and there is an actual supervision.
