A small town in the southern
Appalachian mountains, in mid-April
A mother and daughter spent the
afternoon in the woods hiking and
foraging for “ramp,” a local
delicacy similar to wild onion.
After an idyllic day in the woods,
the women made a casserole from
the ramps they had collected,
adding some potatoes and
canned salmon.
Unfortunately…
The casserole tasted
“terrible.” Thirty to fortyfive minutes after eating
the casserole, both women
developed nausea,
vomiting, and extreme
weakness.
They arrived in the local emergency
department one hour post ingestion.
