In Negros Occidental, oysters, or talaba, as what the locality calls it, can be found in all the coastal areas in the province. Though there are places that are major oyster producers like the city of Himamaylan and the municipality of Ilog, the talaba of Hinigaran are deemed the best. Some sources say that oyster culture in the Philippines began at Hinigaran in 1921. Hinigaran has natural breeding grounds for “spats” or veliger larvae of talaba.

Though oysters are usually enjoyed half-cooked to preserve its delicious taste, some people eat it raw, with millions of Americans eating it au naturel with a squeeze of lemon or a dash of hot sauce. However, when eaten like this, this tasty mollusk can pose certain health risks.

Eating raw oysters exposes people to certain kinds of bacteria and human gastric pathogens they naturally harbor, examples of which include the Vibrio parahaemolyticus and the Vibrio vulnificus bacteria. Vibrio vulnificus is a naturally occurring bacterium found in marine waters, particularly those waters with low salinity levels such as bays and estuaries. The bacterial population is typically greatest during the summer months when water temperatures rise. Because oysters are filter feeders, meaning they filter water containing plankton and food particles through gills, it is common for Vibrio vulnificus to become concentrated in their tissues when feeding in waters where bacteria thrive. This kind of bacteria will not only cause gastrointestinal illness like the other Vibrio bacteria that can also be found in oysters, Some people with certain health conditions can suffer serious illness or even death when infected with Vibrio vulnificus.
