Good morning. I want to buy this product for Pesach. https://www.mykoshermeat.com/center-cut-tuna-loins-by-kahuna.html
Should there be a concern that this fish could have been packed with corn starch and/or could have been glazed in corn syrup. Thank you very much.
While I can not see the link that you attached, however in general frozen fish needs to be certified kosher for Passover, for the exact concern that you mentioned.
