Salmonella





Salmonella is a disease-causing bacteria that can be transmitted from animals to humans. It usually spreads by means of animal waste, contaminated water, or contaminated animal food products. Salmonella was discovered by Theobald Smith in 1885, but named for the administrator of the USDA Research Program, Dr. Daniel Elmer Salmon. The first L in Salmonella is usually pronounced aloud, as the bacteria  is named for  Dr. Salmon, not the salmon fish.

CUTE & CONTAGIOUS Turtles and other Reptile pets to have

The little glassy–eyed creatures may look cute and harmless, but small turtles can make people very ill. Turtles commonly carry bacteria called Salmonella on their outer skin and shell surfaces. People can get Salmonella by coming in contact with turtles or their habitats.

Salmonella can cause a serious or even life-threatening infection in people, even though the bacteria do not make turtles sick. An example is the 2007 death of a four-week-old baby in Florida linked to Salmonella from a small turtle. The DNA of the Salmonella from the turtle matched that from the infant.
People infected with Salmonella may have diarrhea, fever, stomach pain, nausea, vomiting, and headache. Symptoms usually appear six to 72 hours after contact with the bacteria and last about two to seven days. Most people recover without treatment, but some get so sick that they need to be treated in a hospital.

Ages not to have pet turtles are:

  • Infants
  • young children
  • elderly people
  • "All reptiles (turtles, lizards, snakes) and amphibians (frogs, salamanders), are commonly contaminated with Salmonella," says Joseph C. Paige, D.V.M., a Consumer Safety Officer in the Food and Drug Administration's Center for Veterinary Medicine. "But it is the small turtles that most often are put in contact with young children, where consequences of infection are likely to be severe." Because of this health risk, since 1975, FDA has banned the sale of small turtles with a shell less than four inches long.
  • "Young children are ingenious in constructing ways to infect themselves," says Paige. "They put the small turtles in their mouths or, more often, they touch the turtles or dangle their fingers in the turtle tank water and then put their hands in their mouths. Also, sometimes the tanks and reptile paraphernalia are cleaned in the kitchen sink, and food and eating utensils get cross–contaminated."
  • Surfaces such as countertops, tabletops, bare floors, and carpeting can also become contaminated with the bacteria if the turtle is allowed to roam on them. The bacteria may survive for a long period of time on these surfaces.

ADVICE FOR CUSTOMERS

  • Don't buy small turtles for pets or as gifts.
  • If your family is expecting a child, remove any pet turtle (or other reptile or amphibian) from the home before the infant arrives.
  • Keep turtles out of homes with children under 5 years old, the elderly, or people with weakened immune systems.
  • Do not allow turtles to roam freely through the house, especially in food preparation areas.
  • Do not clean turtle tanks or other supplies in the kitchen sink. Use bleach to disinfect a tub or other place where turtle habitats are cleaned.
  • Always wash hands thoroughly with soap and water after touching any turtles, their housing, or anything (for example, food) that comes in contact with a turtle or its housing.
  • Be aware that Salmonella infection can be caused by contact with turtles in petting zoos, parks, child day care facilities, or other locations.
  • Watch for symptoms of Salmonella infection, such as diarrhea, stomach pain, nausea, vomiting, fever, and headache. Call your doctor if you or your family have any of these symptoms.

Although many people think of salmonellosis as an illness caused by contaminated food, it can also be caught by handling a turtle or by contact with its environment. Salmonella occurs naturally in turtles and does not usually make the animals sick. You cannot tell by looking at a turtle whether it is carrying Salmonella. Salmonella bacteria are easily passed from turtles to people. Research shows that a person who handles turtles can easily pass germs to others because bacteria are able to cling to clothing and other surfaces such as our hands. Despite this, most people are not aware of the risk of Salmonella infection from turtles.

Since 1975, it has been illegal in the United States to sell or distribute turtles with shells that measure less than 4 inches in length. This size was chosen because small children are more likely to treat smaller turtles as toys and put them in their mouths. This ban prohibiting the sale of small turtles likely remains the most effective public health action to prevent turtle-associated salmonellosis. Despite this ban, such turtles are still found in some pet stores, flea markets, with street vendors, or sold over the Internet. In addition, children still catch wild turtles and lizards and bring them home to keep as pets. Whether purchased or caught in a backyard, a reptile or amphibian can carry Salmonella and might not be the best choice of a pet for your family, especially if there are young children or persons with weakened immune systems in the household.

I think having reptiles for pets is fun. But it is very dangerous. It is very contagious, and there are a lot of symptoms for it. My doctor says the American Academy of Pediatrics says “children and turtles” don’t mix.

History of Famous Landmarks & Monuments - Statue of Liberty




The Statue of Liberty National Monument officially celebrated her 100th birthday on October 28, 1986. The people of France gave the Statue to the people of the United States over one hundred years ago in recognition of the friendship established during the American Revolution. Over the years, the Statue of Liberty's symbolism has grown to include freedom and democracy as well as this international friendship.

Sculptor Frederic Auguste Bartholdi was commissioned to design a sculpture with the year 1876 in mind for completion, to commemorate the centennial of the American Declaration of Independence. The Statue was a joint effort between America and France and it was agreed upon that the American people were to build the pedestal, and the French people were responsible for the Statue and its assembly here in the United States. However, lack of funds was a problem on both sides of the Atlantic Ocean. In France, public fees, various forms of entertainment, and a lottery were among the methods used to raise funds. In the United States, benefit theatrical events, art exhibitions, auctions and prize fights assisted in providing needed funds.

Meanwhile in France, Bartholdi required the assistance of an engineer to address structural issues associated with designing such a colossal copper sculpture. Alexandre Gustave Eiffel (designer of the Eiffel Tower) was commissioned to design the massive iron pylon and secondary skeletal framework which allows the Statue's copper skin to move independently yet stand upright.

Financing for the pedestal was completed in August 1885, and pedestal construction was finished in April of 1886. The Statue was completed in France in July, 1884 and arrived in New York Harbor in June of 1885 on board the French frigate "Isere" which transported the Statue of Liberty from France to the United States. In transit, the Statue was reduced to 350 individual pieces and packed in 214 crates. The Statue was re-assembled on her new pedestal in four months time. On October 28th 1886, the dedication of the Statue of Liberty took place in front of thousands of spectators. She was a centennial gift ten years late.

The story of the Statue of Liberty and her island has been one of change. The Statue was placed upon a granite pedestal inside the courtyard of the star-shaped walls of Fort Wood (which had been completed for the War of 1812.) The United States Lighthouse Board had responsibility for the operation of the Statue of Liberty until 1901.

After 1901, the care and operation of the Statue was placed under the War Department. A Presidential Proclamation declared Fort Wood (and the Statue of Liberty within it) a National Monument on October 15th, 1924 and the monument's boundary was set at the outer edge of Fort Wood.
In 1933, the care and administration of the National Monument was transferred to the National Park Service. On September 7, 1937, jurisdiction was enlarged to encompass all of Bedloe's Island and in 1956, the island's name was changed to Liberty Island.

On May 11, 1965, Ellis Island was also transferred to the National Park Service and became part of the Statue of Liberty National Monument. In May of 1982, President Ronald Reagan appointed Lee Iacocca to head up a private sector effort to restore the Statue of Liberty. Fundraising began for the $87 million restoration under a public/private partnership between the National Park Service and The Statue of Liberty-Ellis Island Foundation, Inc. In 1984, at the start of the Statue's restoration, the United Nations designated the Statue of Liberty as a World Heritage Site.
On July 5, 1986 the newly restored Statue re-opened to the public during Liberty Weekend, which celebrated her centennial.
