If the babysitter isn’t Jewish, there are a few things to keep in mind to maintain your home's kosher status:
Non-Jews can’t cook for Jews unless a Jew lights the fire (bishul akum), as food cooked solely by a non-Jew can render both the food and cookware non-kosher.
Uncooked (non-mevushal) wine must also be inaccessible to non-Jews to prevent it from being handled and becoming non-kosher.
Non-Jewish helpers left unsupervised in the home could inadvertently cause kashrut violations, such as using non-kosher food or utensils, or mixing meat and milk.
There are several options to prevent kashrut concerns when a non-Jewish babysitter or helper is left alone at home:
- Simply limit or lock access to the kitchen.
- Implement a yotzei v'nichnas system, where you explicitly instruct the sitter not to use kitchen items and arrange for Jewish household members to make unannounced check-ins.
- Install monitored security cameras in the kitchen and inform the sitter of the surveillance.
Any of these systems work because the possibility of being caught prevents the sitter from mishandling kosher items.
If supervision is insufficient, restrict access to kosher-sensitive items like meat, dairy, bread or non-mevushal wine to prevent substitution with non-kosher food. Pots, pans, and ovens should also be secured to avoid their use for non-kosher food or mixing meat and dairy. You don’t have to lock everything; taping cabinets or disabling appliances (e.g., shutting off the oven) is good enough.
If you do need the caregiver to prepare hot food, speak to a rabbi since the halachah would depend on the type of food and other factors.
