Hi, this is my first post and I am certainly not an expert, but aren't there DEFRA rules and regs about what would essentially be exporting/importing non-native species?

For example, if someone sent me some broad beans and I planted them not noticing that they had small holes in them, isn't there a chance of me introducing a non-native pest into the UK?

Wouldn't surprise me if the same applies to the US, and I do know that the Australians are quite touchy about anyone taking things like fruit into the country. The Australian and New Zealand flatworms were introduced accidently here and are causing a bit of a ruckus at the moment too!
