Texas residents Vicki Bergquist and wife Jeanette LeBlanc were visiting family in Louisiana. They went crabbing with friends and family on the coast, picking up a sack of raw oysters in a market in Westwego. It wasn't long after when LeBlanc's health rapidly declined, CBS affiliate KLFY reports.
The couple's friend Karen Bowers says she and LeBlanc shucked and ate about two dozen raw oysters.
"About 36 hours later she started having extreme respiratory distress, had a rash on her legs and everything," Bergquist said.
"An allergic reaction of sorts, that's what I would call it. That's what we thought," Bowers added.
LeBlanc's condition went from bad to worse in the first 48 hours.
Doctors told Jeanette she had vibrio — a potentially deadly bacterial infection.
