As noted from other posts, do check on the regulations and requirements of permitted and prohibited foods in order to give you the heads up, but do also keep in mind two scenarios that could encounter as well :
-Current regulations and requirements could be subject to change at any given day
-Any type of food thats listed as a permitted item could possibly change at the discretion of the customs officer if they feel any doubt or suspicion of the food from it's origin (unlikely event however it has happened on more than one occasion for the traveler)
The best advice on bringing food items upon crossing the USA-CANADA Border :
-Declare ALL food items only when asked while staying within the current limits allowed for certain permitted foods, as the worst case scenario will not hit someone's wallet and cost the traveler $0.00 along with confiscation of any determined prohibited items.
-Undeclared food could (or undeclared prohibited food will) lead to confiscation anyway, in addition to costing the traveler an amount up to :
$800.00 fine in Canada
$300.00 fine in United States
$220.00 fine in Australia (without going to court or contesting the offense) as this fine would be much greater in the thousand of dollars if found guilty in a court of law, Australia has such strict rules upon importing a variety of foods within their country
I believe I seen practically every episode of Border Security shows posted on YouTube of these three countries as it gives the viewer a great idea on how each customs agency works upon entering their respected country, as it mindboggles me on why many people still insist by not declaring any food or concealing food upon entering these three countries while subject to fines, as just a simple declaration of possessing any sort of food will cost the traveller nothing while the declared food will either be confiscated or permitted to keep.
I generally practice the no possession of any produce, meat, and dairy products upon crossing borders as I will stock up on these products after entering Canada or returning to the United States as I will always declare even the permitted foods I have in possession whenever asked (I for one like to get cleared by customs the least amount of time possible without giving them anymore additional excuses to delay the border crossing process upon their discretion), as you never know if one day they might all of a sudden classify that can of soup or that chocolate bar or that bag of chips as a prohibited item as no food of anykind is subject to a fine by simply declaring it when asked.
