Can airport x ray scan detect seeds?

[RobertFisher]

I once accidentally transported live plant seeds across countries. When cleaning my luggage I discovered in one of my luggage pockets there are some lychee pits and skin. There were garbage that I stuck there for the time being and completely forgot about them. At the time I discover them, they had traveled in and out of maybe 10 countries.

So I am wondering, what's with the airport x ray machines? Can they detect plant seeds which most countries prohibit importing?

I think you answered your question.

The USDA uses sniffer beagles for that kind of inspection work at many US points of entry because they're food driven and non-threatening to passengers.

What are the USDA rules regarding Pulses? Things like pigeon peas, chick-pea or beans? Many international travellers do bring food stuff like pulses and spices. While rules about ban on meat & dairy products are clear, I am not sure whether this kind of pulses beans are considered live seed?

I went through with a bag of kitty litter and the line came to a screeching halt! Once I identified the substance they declined reaching in - though my cat didn't mind if they did. He hadn't used it yet.
