“I never thought that a mouse could have salmonella. It just never entered my mind.”
So says Steve Gilfillan, 51, a deputy sheriff in Council Bluffs, Iowa, who, according to the New York Times this morning, keeps “a couple hundred” garter 
snakes in several neat rows of roomy enclosures in his basement. The snakes, he said, are like part of the family, which leads to a certain familiarity.
“As far as precautions, I don’t know,” said Mr. Gilfillan, adding his three children helped feed and care for his pets. “Snakes got to eat and snakes got to poop and you got to clean it up. It’s just the nature of keeping them.”
More than 400 people, many of them snake owners or their children, in the United States and Britain, have been sickened by salmonella outbreaks, all traced to frozen mice sold over the Internet as food for exotic pets by a small Georgia company called MiceDirect.
The company announced this week a recall involving millions of frozen mice and said that it would begin irradiating future shipments to kill infectious bacteria.
MiceDirect also recalled frozen rats and baby chickens used as pet food by reptile fanciers, although those products had not been linked to the salmonella outbreaks.
Health officials said that owners of reptiles should be mindful that such pets, including snakes and turtles, often carry salmonella and have been the cause of outbreaks in the past. Rodents carry similar risks, whether kept as pets or used as food for other animals.
Snakes can become infected after eating tainted mice, although the snakes may show no signs of illness, said Dr. Casey Barton Behravesh, a veterinarian and epidemiologist with the Centers for Disease Control and Prevention. Snake owners can become sick from handling the frozen or thawed mice, handling infected snakes or cleaning feces from an enclosure.
Mr. Gilfillan and many other snake owners thaw mice to serving temperature in warm water. Dr. Barton Behravesh said people should not use a microwave oven, because the bacteria could spread to other food.
She also said that mice and reptiles should be kept out of the kitchen and away from areas where food is served. Reptile cages should not be cleaned in the kitchen sink, she said, and mice should not be kept in a freezer with food for humans.
And she said that reptile owners should wash their hands thoroughly after handling their pets or the rodents the pets eat.
The first salmonella outbreak linked to MiceDirect began in Great Britain in August 2008. Since then, more than 400 people have fallen ill there, about two-thirds of them have been children under 10, according to Chris Lane, a senior epidemiologist of the Health Protection Agency’s Center for Infections in London. Although the shipments of tainted mice were halted last year, people continue to get sick there, Mr. Lane said.
The first case in the United States appeared in January 2010, according Dr. Barton Behravesh. The C.D.C. has identified more than 30 cases in 17 states with the same strain as the British outbreak. She said the cases were not concentrated in one region but spread across the country. Half the victims were under 12.
Accounts from both sides of the Atlantic suggest that American authorities were slow to react to indications of a problem.
British investigators looking into the outbreak found that many of the victims came from families where snakes were kept as pets. They eventually began looking at the frozen mice fed to the snakes and found shipments from MiceDirect that contained the same strain of salmonella as that isolated from the victims.
British officials contacted MiceDirect, Mr. Lane said, and the company promised to act to prevent further contamination.
On July 21, 2010, the F.D.A. told the company that tests of its products and plant had found salmonella. Two days later, the agency said, MiceDirect agreed to a recall.
But the recall effort has been haphazard. The company’s recall notice was not prominently posted on its Web site until Thursday. And neither the company’s site nor the F.D.A.’s site gave clear instructions on what to do with mice that customers still had.

In light of these new cases, the FSAI advises caterers to be particularly strict in adhering to best hygiene practices and to only serve duck eggs or duck egg products that have been thoroughly cooked prior to consumption. It also reiterates the need for strict procedures to be followed at all times to avoid cross contamination between raw and cooked foods.

Health Canada used to say raw sprouts should be avoided if concerned about illness, but now they are more direct. That 2005 outbreak in Ontario involving more than 648 cases of Salmonella linked to mung bean sprouts may have something to do with the newfound directness.

Safeway, the parent of Dominick’s food stores, contacts shoppers directly in some recalls — typically smaller ones, said spokesman Brian Dowling. But in larger recalls, he said the company’s stores rely on other methods to get the word out, such as notices on store shelves and stories in newspapers and on TV and radio.
