Turtles bought from a particular website in the US have been linked to a salmonella outbreak.
Some 15 people, including children, across 11 states have become infected with the outbreak strain of the bacteria, according to the Centers for Disease Control (CDC).
So far, five people have been sent to hospital as a result of the outbreak, but no one has died, the CDC said.
The government agency adds the actual number of people who have become ill is likely higher than reported, due to them recovering and not being tested.
After carrying out interviews and analysing lab data, the CDC discovered small turtles were the culprit in most cases, with half of those who had bought a pet reptile doing so from myturtlestore.com.
Sky News has contacted the store for comment.
In the US, federal law bans the sale of small turtles that have shells shorter than four inches, due to worries children could put them in their mouths and contract salmonella.

However, any size turtle can carry the bacteria in their droppings, even if they are healthy and clean, which can then spread to their bodies and the water in their tanks.
From there, humans can become poorly by touching turtles or anything in its living environment and transferring those germs to their mouths.
When it comes to purchasing turtles, CDC guidance says:
• Only buy turtles with shells longer than four inches and buy them from reputable pet stores or rescues;
• Stay healthy around your pet turtle by always washing your hands after touching, feeding, or caring for your turtle;
• Adults should make sure young children are washing their hands properly;
• Don’t toss your turtle if you decide you no longer want it. Reach out to your local pet store or reptile rescue;
• Pick the right pet for your family – pet turtles are not recommended for children younger than five, adults aged 65 and older, and people with weakened immune systems as they are more likely to get a serious illness from germs that turtles can carry.
Symptoms of salmonella infection include stomach cramps, diarrhoea, and a fever, with illness usually presenting itself a few days after infection.
