Study directly links increase in vibrio cases to global warming trend

A recent study may be the first one to link a warming trend in sea surface temperatures to the spread of vibrios and the human diseases which can be caused by pathogenic strains. “In this study, for the first time to our knowledge, experimental evidence is provided on the link between multidecadal climatic variability in the… Continue Reading

FDA sued for failing to impose regs about shellfish bacteria

The 5 Most Dangerous Foodborne Pathogens

It can be tricky business to say that one foodborne pathogen is more dangerous than another. Are the criteria the number of illnesses, number of deaths, or percentage of victims who die? Do the severity of an illness or chronic side effects factor into the ranking? The first three pathogens on this list are fairly obvious dangers and ones… Continue Reading

Oysters Can Harbor Dangerous Pathogens in Summer Months

The warmer coastal water temperature produced by summer weather creates ideal conditions for bacteria that can contaminate oysters, the Washington State Department of Health reminded the public over the Fourth of July weekend. Vibrio vulnificus and Vibrio parahaemolyticus, two types of bacteria that grow in warm waters and can cause human illness, are known to… Continue Reading

Still Too Many Raw Oyster Deaths in Gulf States

There’s red tide in Texas, salinity levels in state waters are way off in Mississippi, and Louisiana has fallen behind Washington state in oyster production. To say Gulf oystermen have not had much cause for optimism since the 2010 BP oil spill is to put it lightly. Gulf oyster production — at about 15 million… Continue Reading
