Dear Rabbi Simon,
What do we do if for instance, you’re eating a bowl of cereal and a small bug lands in your bowl? Does one need to calculate the volume of the insect against that of the contents of the bowl, re 1:60 threshold?
Thanks
Cyril
Hi Cyril
Thank you for your practical (if slightly unappetizing) question.
The answer is, just remove the insect and enjoy the rest of the cereal. (On Shabbos, remove some cereal and/or milk with the insect to avoid the prohibition of borer [sorting, ie removing detritus from a mixture]).
In the case of cold cereal, no taste is imparted by the bug, so there is no need to calculate 1:60. In the interest of thoroughness: If the cereal is hot, eg, porridge, further investigation/clarification may be necessary. If this happens, get in touch to discuss.
Best wishes
Rabbi Rashi Simon
