The oyster lover’s axiom of edibility — that this shellfish is safest to eat in any month with an “r” in it — may soon become somewhat of a culinary anachronism, thanks to a new food-safety test developed with help from the
University of Florida. Oysters are typically considered safest to eat in cooler months (September through April) because the shellfish-infecting bacteria in the genus Vibrio flourish best in warm temperatures.
Even in the “r” months, slurping an oyster opens some people to infection from these bacteria, which can cause fever, nausea, abdominal pain, diarrhea and has even led to finger amputation when it’s given a chance to penetrate a cut or skin lesion.
However, a new quick and inexpensive diagnostic test developed by DuPont Qualicon and refined by
UF’s Institute of Food and Agricultural Sciences could make weeding out pathogen-loaded oysters much more practical and efficient. Oysters are a $14 million industry in the Sunshine State, according to the
Department of Agriculture and Consumer Services.
