Domestic passengers flying within the United States or Canada do not need to declare packaged food. However, international travelers entering any foreign country must declare all agricultural items, fresh fruits, vegetables, and meats on their customs declaration card to prevent biological contamination and avoid fines up to $10,000.

If prohibited items like Cheese wire are discovered at checkpoint screening, screeners will prohibit entry past the security perimeter. You must voluntarily surrender the item for disposal, return landside to pack it in checked luggage, hand it to a non-traveler, or risk law enforcement referral.
