Raw meat
Beef, poultry and seafood
There are many disease-carrying pathogens found in raw meats, and they differ according to the source, whether it be mammalian, poultry or seafood. Some disease-carrying pathogens found in beef are Salmonellas, Escherichia coli, Shigella, Staphylococcus aureus, and Listeria monocytogenes. Different varieties of Salmonellas are often found in contaminated poultry. Seafood itself can also contain a wide variety of pathogens. The most common pathogen in raw oysters is Vibrio gastroenteritis, while Salmonella, Plesiomonsas shielloides, and staphylococcus are found in contaminated raw shrimp, and Vibrio cholerae has been found in raw crabmeat. Many of the symptoms that result from these diseases involve intestinal damage and can have potentially fatal effects for those at risk. The symptoms of an E. coli infection include bloody diarrhea, severe abdominal pain, and possible complications for the immune-compromised, elderly or children. These complications can include Haemolytic uraemic syndrome (HUS) and neurological problems. The symptoms of Vibrio gastroenteritis include frequent fevers, bloody diarrhea, long duration of illness and hospitalization. While most of these diseases are still most commonly found in raw meat, the instances of detection in other mediums are increasing. For instance, Salmonella is most commonly found in poultry, but has been recently identified in sources such as eggs, dairy, meat, fresh vegetables and fruits. E. coli has also been found in beef, lamb, lettuce, sprouts, fruit juices, vegetables, raw milk, and water. Possible reasons for the increase are the globalization of the food market, improper handling, and leakage.
