Salmonella spreads from frogs to humans

Think carefully before deciding to buy aquatic animals at home, according to US researchers at the Centers for Disease Control and Prevention .

You buy a frog home to make a scene means you are at risk because the salmonella bacteria in the frog body can spread and cause illness for you and your loved ones . African dwarf frogs contain salmonella bacteria that have infected more than 113 people, mostly children, according to the Centers for Disease Control and Prevention, Atlanta, USA. Salmonella is naturally present in the intestine, in the feces of animals such as pigs, cows, poultry, turtles, snakes, reptiles, .

Beef, pork, chicken, chicken eggs, unpasteurized fresh milk, fish, shrimp, oysters, snails, fruit and vegetables, sprout, etc. can all be infected with Salmonella.

" This is the first time an outbreak of disease from frogs carrying Salmonella, " said Shauna Mettee, a public health nurse working at the Centers for Disease Control and Prevention, Atlanta, USA. presented these findings at a meeting of the Infectious Diseases Society of America, on October 22, 2010.

The researchers went after doctors were informed of the massive occurrence of Salmonella typhimurium in 2009. Between April 2009 and March 2010, Shauna Mettee and her colleagues identified 113 cases of this disease, three quarters occurred in children under 10 years of age. The average age of the patient is 5. Hospitalized patients have symptoms from cramps to bloody urination but no deaths.

Bacteria spread in many forms. For example, a woman cleans an aquarium used to feed frogs in the kitchen sink and then bathes a 3-week-old infant in it, Mettee said.

From infected frogs, researchers discovered a breeding facility and traded between 800,000 and 1 million African dwarf frogs. The health agency is working with the owner of the facility to perform cleaning procedures designed to limit the spread of salmonella bacteria to the outside environment.

" Children should avoid any contact with farmed frogs and don't keep them in the house ," Mettee said.

James Hughes, an infectious disease specialist at Emory University School of Medicine, Atlanta, USA, said these findings, " will remind us of the importance of hand hygiene with soap, in kitchen and other areas of the house, especially if your family has pets or reptiles in the home ".

Amphibians and reptiles can carry salmonella without disease , according to Patricia Griffin, a doctor and director of the epidemiology branch of intestinal diseases at Atlanta's Centers for Disease Control and Prevention. States

Even though, baby turtles, which were popular pets in families in the 1970s, have been banned since scientists discovered that Salmonella is present on their bodies, but now they are Still sold on the streets, according to Mettee.

Since March 31, 2010, there have been 57 more cases of infection caused by Salmonella typhimurium, now Mettee and colleagues are investigating whether these cases are related to the number of frogs raised. at the African dwarf frog facility.
