Respectfull, baloney. From a sanitation point of view, eating fresh local food cooked on a grill in front of me where I can watch the process and "supervise" the level of cooking and the handling, is far less risky than eating Chinese processed food...or for that matter, certain dishes prepared behind the scenes at upscale restaurants. I'll stand by what I said earlier, Chinese food processing plants are too variable in their quality of preparation and packaging. All the years I spent in China cooking in my own kitchen, I can count on one hand the number of times I ever purchased a Chinese processed food product to take home and use, either as-is or as a component. Seriously. For me it was fresh food only, or buy imported for pantry-type items.

On a different note, a proper Beijing duck roasted in the classic oven and carved at the table--with trimmings--is a sublime pleasure. Relegating a duck to the inside of a vacuum bag is IMO close to an unpardonable sin of the food universe. I'm still trying to come to grips with a planet that puts the magnificent tuna into cans.

I do agree that if the OP insists on traveling with this duck, declaring it is a better strategy than trying to sneak it through. And if the beagles are patrolling around, one is toast. I used to own a beagle--which are noses with fur and legs. Their capabilities are uncanny and in a contest between the USDA Beagle and the Vacuum Duck, my money's on the dog.
