I’m not sure how you’d test lettuce for this and achieve reliable results. The parasite is microscopic and isn’t going to show up all over, say, a head of lettuce. I don’t think a sample would give you accurate information.
Probably the best way to know is like this story, when an outbreak shows up and can be traced to produce where the source is known.
I’m limiting myself to greenhouse grown fresh produce for the duration; I’m not sure if even that is reliable, because cross contamination might occur anywhere across supply lines, so...
Sorry; I meant 15 to go to ‘bullish’.
What you did there.
I see it.
