The oranges made by ocean spray sweet mandarins are a product of Israel it is distributed by 1 world fruit sold in SHINS on Avenue M. One should discuss with a Rav if he cooked with it whether the pots are kosher!
Does using a pot to prepare something that has kedushas sheviis make the pots treif?
Not treif, but it has kedushas shviis, and must be treated appropriately. Just like if you bake your separated challah piece into something.
Speak to your LOR.
That’s the food, but that has nothing to do with the status of your pots, as asked in the OP.
That’s why you should ask a Rov. Just like treif food makes a pot treif, shviis food makes a pot shviis.
LiF, please let us know what your Rov says.
Perhaps LIF was referring to the possibility of produce from
a field (etc.) that was worked on during shmitta being assur.
