Not sure about sheep specifically, Rb, but the parasite finds its way into the water courses where the watercress grows via the droppings of drinking cattle etc.
I'm feeling a bit guilty now, about highlighting this 'liver fluke' issue.
Be assured that the stuff you buy from supermarkets and other retailers will be commercially grown and represent absolutely no risk...as will that grown in the garden & allotment.

I've grown watercress from seed in containers of compost for years now, just keep it watered and feed occasionally with high nitrogen feed.
