SpeakPolish said:If those peppers have a virus or bacteria. Not necessarily for peppers but for citrus fruits there are pathogens in other countries that would absolutely destroy our citrus. Same thing with bananas.
Not only virus & bacteria an issue but other invasive species an issue:
The brown marmorated stink bug (Halyomorpha halys) is an insect in the family Pentatomidae, native to China, Japan, the Korean Peninsula, and Taiwan. In September 1998 it was collected in Allentown, Pennsylvania, where it is believed to have been accidentally introduced.
The invasive brown marmorated stink bug causes problems for homeowners and farmers and threatens U.S. specialty crops valued at over $20 billion.
