I have a friend who works as an inspector for Agriculture Canada (farms during growing season, importers during winter), and foodstuffs coming in are watched closely. Their focus is on products coming in from areas with a temperate climate (tropical bugs won’t survive a winter here). Bring back a live plant or fresh produce from overseas and I can pretty much guarantee that they will seize it and incinerate it the same day.
Then some idiot swabbie on a cargo ship empties the bilge water into Lake Ontario and the zebra mussels play hell with the water supply for 50 million people...
Zebra mussels plague my inland area also.
I understand limiting ag pests, but cured meats from italy, chocolates and beer from canada and germany, and spice packets from singapore/malaysia are of no threat to anyone. Even smoked sausage from Costa Rica was no real threat.
