Golden Nematode and Pale Cyst Nematode do not pose a risk to
human health. These two species of Potato Cyst Nematode (PCN) are considered
quarantine pests because they can reduce yields of potatoes and other host
crops such as tomatoes and eggplants by up to 80 per cent. These pests infest
the soil and are very difficult to eradicate because they can persist, dormant
in the soil, for several decades.
Both of these quarantine Potato Cyst Nematodes have been confirmed in 65
countries worldwide, including the United States. In Canada, Golden Nematode is
present in Newfoundland, Vancouver Island and now in Quebec. Pale Cyst Nematode
is only present in Newfoundland. Strict quarantine measures are in place to
prevent the potential spread of these PCNs.
