We're hoping to head down to the U.S. in a couple of weeks or so with our motorhome, and this will be our first cross border trip in the motorhome. (Saw an almost white rabbit in our yard today, it's time to head south, lol!)

I am wondering what sort of groceries the customs officials allow across. I realize we can't cross with fresh produce and meat products, but what about canned goods, dry goods, and dairy? Also, do dry goods have to be in original packaging? (I have some items stored in smaller quantities in plastic storage containers--stuff like flour, sugar, and rice.)

you can cross with beef,pork,fish and fowel(chicen/turkey) No veal or LAMB
Dairy is fine and dry goods is a total non issue.DO NOT take any produce at all as its totally prohibited,no plants at all,US only dog/cat food*(even though there wrong on that but why argue)
