Information – Food Poisoning Journal – Listeria – Salmonell – Norovirus

FPJ – Listeria is the common name for the pathogenic or disease-causing bacterium known as Listeria monocytogenes. It is a foodborne bacterium that, when ingested, causes an infection known as listeriosis.[1] Approximately 2,500 illnesses and 500 deaths are attributed to listeriosis in the United States annually.[2]

FPJ – It has long been said that, in 1885, pioneering American veterinary scientist, Daniel E. Salmon, discovered the first strain of Salmonella. Actually, Theobald Smith, research-assistant to Dr. Salmon, discovered the first strain of SalmonellaSalmonella cholerae suis. But, being the one in charge, Dr. Salmon got all the credit. In any case, today the number of known strains of the bacteria totals over two thousand. In recent years, concerns have been raised, as particular strains of the bacteria have become resistant to traditional antibiotics, in both animals and humans.

FPJ – The Centers for Disease Control and Prevention (CDC) estimates that noroviruses cause nearly 21 million cases of acute gastroenteritis annually, making noroviruses the leading cause of gastroenteritis in adults in the United States. [1] According to a relatively recent article in the New England Journal of Medicine:

USA – Vibrio vulnificans in 2014 – 7 Dead

Outbreak News Today V

The Florida Department of Health (DOH) has reported an additional case of Vibriosis caused by the bacterium, Vibrio vulnificus in Pinellas County in the west-central part of the state. This is the fourth V. vulnificus case reported from Pinellas County this year.

This brings the state total to 32 cases and the death toll remains at seven.

The Centers for Disease Control and Prevention (CDC) says Vibrio vulnificus is a bacterium in the same family as those that cause cholera and Vibrio parahaemolyticus. It normally lives in warm seawater and is part of a group of vibrios that are called “halophilic” because they require salt.

Listeria is the common name for the pathogenic or disease-causing bacterium known as Listeria monocytogenes.  It is a foodborne bacterium that, when ingested, causes an infection known as listeriosis.[1]  Approximately 2,500 illnesses and 500 deaths are attributed to listeriosis in the United States annually.[2]

Listeria is ubiquitous in the environment, and can be isolated from wild and domestic animals, birds, insects, soil, wastewater, and vegetation.  The bacterium easily comes into contact with farm animals, as it has been found to be present in grazing areas, stale water, and poorly prepared animal feed.  In addition to being present in the environment, Listeria can live in the intestines of humans, animals, and birds for long periods of time without causing infection.
