Sources of Infection
- Infected food, often gaining an unusual look or smell, then is introduced into the stream of commerce;
- Poor kitchen hygiene, especially problematic in institutional kitchens and restaurants because this can lead to a significant outbreak;
- Excretions from either sick or infected but apparently clinically healthy people and animals (especially endangered are caregivers and animals);
- Polluted surface water and standing water (such as in shower hoses or unused water dispensers);
- Unhygienically thawed fowl (the meltwater contains many bacteria);
- An association with reptiles (pet tortoises, snakes, iguanas and frogs, but primarily aquatic turtles) is well described.
Salmonella bacteria can survive for some time without a host; thus, they are frequently found in polluted water, contamination from the excrement of carrier animals being particularly important.

Famous quotes containing the words sources of, sources and/or infection:
“On board ship there are many sources of joy of which the land knows nothing. You may flirt and dance at sixty; and if you are awkward in the turn of a valse, you may put it down to the motion of the ship. You need wear no gloves, and may drink your soda-and-brandy without being ashamed of it.”
—Anthony Trollope (1815–1882)
“Even healthy families need outside sources of moral guidance to keep those tensions from imploding—and this means, among other things, a public philosophy of gender equality and concern for child welfare. When instead the larger culture aggrandizes wife beaters, degrades women or nods approvingly at child slappers, the family gets a little more dangerous for everyone, and so, inevitably, does the larger world.”
—Barbara Ehrenreich (20th century)
“No science is immune to the infection of politics and the corruption of power.”
—Jacob Bronowski (1908–1974)
