Salmonella Q & A
Salmonella Q & A addresses common concerns about Salmonella bacteria in desert tortoise care, covering risks, prevention, symptoms, and safe handling practices to protect tortoises and owners from infection.
What is Salmonella?
Salmonella, named after its discoverer, Daniel Edward Salmon (1850-1914), is a bacterium. Bacteria are microscopic one-celled organisms, the simplest form of life. Salmonella is considered a zoonosis, that is, a disease that can be transmitted from animals to man.
Salmonella Sources
There are many sources of Salmonella. The most common are meat, chicken & eggs. Other sources include cattle, pigs, dogs, cats, flies, ducks & their eggs, rats, mice, hamsters, rabbits, cockroaches & reptiles. As you can see, any animal can carry & transmit Salmonella.
Transmission Methods
How Do I Get Salmonella?
Undercooked chicken, eggs and meat are typical sources. Unclean cages and animals that walk through waste products in their cage are common ways to transmit Salmonella to reptile keepers. Transmission starts with the fecal matter of the infected animal. It can be picked up as easily as touching the animal or its soiled enclosure. The bacteria cannot travel through the skin. An object with the bacteria must be placed in the mouth in order to introduce the bacteria into the body. Your chances of contracting Salmonella are equal from touching live or raw duck, chicken, or cattle, eggs or reptiles and placing your fingers in your mouth.
Who is at high risk?
Those who are ill, on prescription drugs, those who are immune compromised, the elderly, pregnant women, and children under 5 years of age, including infants and toddlers, should not come in contact with reptiles. If you come in contact with reptiles, or any animal, immediately wash your hands thoroughly with soap and warm water. This is especially important if you come in contact with anyone falling into any of the high-risk categories, ensuring their safety and health protection.
How long after I get symptoms?
If your body does not reject the bacteria, and you become infected, the incubation period lasts from 7-30 hours. Incubation typically occurs between 10-24 hours.
If I Ingest Salmonella
In many cases the bacteria will simply pass through your body unnoticed. If you become infected, a day or two of diarrhea may be the extent of your infection. Most infected people fall into this category thinking they simply had the stomach flu. The Center for Disease Control and Prevention (CDC) recommends you visit a doctor if your diarrhea lasts for more than two days. Other symptoms include headaches, fever & chills, nausea. vomiting and abdominal cramps. If these symptoms arise, see a doctor immediately.
How do I know If my reptile has Salmonella?
There is no way to tell if your reptile has Salmonella just by looking at it. Fecal samples need to be examined by a veterinarian to make this determination.
Should I take my reptile to the veterinarian for a Salmonella check?
No. It is simply not necessary. The CDC does not recommend reptiles be treated for Salmonella. The Salmonella may become immune to the treatment and will be harder to combat if it infects a human. Reptiles live naturally with Salmonella similar to the way dogs live with fleas. It’s best to assume your reptile has Salmonella and handle it accordingly to avoid contracting Salmonella. An infected reptile may not release Salmonella in the feces all of the time. You could make ten or more vet visits and get ten negative results. This is not fully understood, however, stress seems to play a large role in the way reptiles release salmonella. The CDC reports that salmonella infections from reptiles might constitute 5% of the 2,000,000 total reported cases annually in the United States. The majority of the remainIng 95% are attributed to meat, eggs and poultry.
Do all reptiles have salmonella?
According to the Los Angeles Department of Health, 9 out of 10 reptiles may carry salmonella. As mentioned earlier, they may not always be releasing it. It’s well known that baby green iguanas require their mother’s droppings as a part of their diet. What is not yet determined is whether they require the salmonella bacteria or if it is just a parasite (living within the host animal with no harmful side-effects). Many times reptiles, especially iguanas, are needlessly being destroyed after being the determined source of the salmonella infection within a family.
How long can Salmonella live?
Salmonella may remain viable from weeks to years. Any surface that has been contacted by the bacteria may still have viable salmonella present for years until properly cleaned.
How do I keep from getting Salmonella or spreading it to my family?
The number one precaution you can take is to wash your hands immediately after handling reptiles or their enclosure. Wash with either plain soap and warm water for at least 30 seconds or use anti-bacterial soap. The bacteria can be present on the animal’s skin or surfaces it came in contact with and be transmitted to the hands of those who held it. The bacteria can then be transmitted to anyone or anything that is touched. A simple spray of Lysol’~ can control germs on household surfaces. Do not allow reptiles to roam freely when anyone of high risk is living In the house. Supervise children while handling reptiles and be sure they keep their hands away from their mouths while handling reptiles. Be sure children know they need to wash their hands immediately after handling reptiles (or any animal for that matter).
California Zoological Supply has authored a reference sheet on how to properly clean reptile enclosure in order to best avoid contracting salmonella. Copies may be obtained through most pet stores that carry reptiles. If the pet store in your area does not supply CAL ZOO’S REFERENCE SHEET ON REPTILE ASSOCIATED SALMONELLA, ask that they do.
