Kashrut
Among the numerous laws that form "kashrut" are prohibitions on the consumption of certain animals (such as pork and shellfish), mixtures of meat and milk, and the commandment to slaughter mammals and birds according to a process known as "shechita". There are also laws regarding agricultural produce that might impact the suitability of food for consumption.
Vibrio vulnificus
Increasing seasonal temperatures and decreasing coastal salinity levels seem to favor a greater concentration of " Vibrio" within filter-feeding shellfish of the US Atlantic seaboard and the Gulf of Mexico, especially oysters ("Crassostrea virginica"). Scientists have frequently demonstrated the presence of "V. vulnificus" in the gut of oysters and other shellfish and in the intestines of fish that inhabit oyster reefs. The vast majority of people who develop sepsis from "V. vulnificus" became ill after they ate raw oysters; most of these cases have been men.
