Pesach is a complicated and complex holiday.
But we do banish chometz and any and all manner of leavened bread and grains. The kitchen can become a battle place, with all the cleaning and scrubbing and covering and separating and hiding all-year-round food stuffs.
It can become even more difficult when you go to purchase items and seek out a Rabbinical supervision label. Which Rabbi, which Rabbinate, which company?
And here in Israel, with not-so-friendly rivalry, I found a problematic instance:
If you pay attention you can see that the tuna fish can on the right has contradictory declarations as to whether the contents can be eaten on the Pesach holidy.
Arrow 1 on the can to the left points to “Bishul Yisrael [prepared by Jewish employees], Kosher for Pesach” on the label.
Arrow 2 on the can to the right points to the same text and both are from the Tirat Carmel Rabbinate.
Arrows 3, however, pointing to a yellow label on the can to the right from the Badatz declares the tuna non-edible for Pesach.
