There is a long list of items that are prohibited from being carried on flights. One such is the commonly used poppy seeds or khus khus, which are used in many Indian gravy dishes or sprinkled on breads and buns for that extra crunch. According to aviation expert K Anuradha Suresh, a retired Senior AGM at Air India, carrying poppy seeds on flights can be risky, and in several countries, it is “strictly illegal”. Since poppy seeds come from the opium plant, they can contain trace amounts of opiates (like morphine and codeine), said Anuradha. Carrying them even accidentally in raw form, as a cooking spice (khus khus), or on baked goods can lead to confiscation, severe fines, or immediate detention,” said Anuradha.
