Trader Joe's Everything but the Bagel seasoning, popular for adding flavor to food, is banned in South Korea because of its poppy seeds.
Poppy seeds contain a substance that can be linked to drugs, which is illegal in South Korea, even though the amount in the seasoning is very small.
This has led to a lot of confusion and frustration for travelers who want to bring the seasoning into South Korea, as many have had it confiscated at the airport.
While the likelihood of testing positive for drugs from the seasoning is low, South Korea's strict regulations mean it's still not allowed.
