Bishul Akum with Sardines

Do Sardines Have to Be Bishul Yisroel?

Canned sardines are a very basic staple all over the world. However, in many places canned sardines that are bishul Yisroel (cooked by a Jew) are not available. There is a machlokes haposkim (a debate among poskim) whether canned sardines fall under the prohibition of bishul goyim (cooked by a non-Jew). The consensus is that the prohibition does not apply to sardines. If we ascertain that the canned sardines are kosher and that no non-kosher fish, nor other non-kosher ingredients, have been added (according to many poskim, this might require the presence of a mashgiach temidi during the entire processing), we may eat them—even if they are not bishul Yisroel. In fact, it is known that many great tzadikim ate sardines that were not bishul Yisroel. Among the reasons for this is that sardines are not food that is fit to be served at a royal table, and certainly not canned ones. However, according to many poskim, this leniency does not apply to tuna and other fish.  #289?1
