Is Salmonella Detectable by Smell?

Salmonella is a group of almost 2,000 bacteria living in the intestinal tract of humans and animals. The bacteria are typically passed to humans through fecal contamination. Unfortunately, spotting contamination may be difficult.

  1. Identification

    • Salmonella cannot be detected by smell. There is no way to detect salmonella outside of the laboratory, says the Utah Department of Health.

    Time Frame

    • Symptoms of a salmonella infection (salmonellosis) typical begin within 12 to 72 hours after being infected. The foodborne illness usually resolves itself within four to seven days, explains the Centers for Disease Control and Prevention (CDC).

    Prevention/Solution

    • To prevent salmonellosis, avoid unpasteurized milk, wash fruits and vegetables and thoroughly cook meat and poultry, explains the Illinois Department of Health. To prevent cross contamination, wash cutting boards and utensils if they have been used to handle raw meat, explains the National Institute of Allergy and Infectious Diseases (NIAID).

    Symptoms

    • Salmonellosis may induce symptoms that include diarrhea, stomach cramps, fever, headaches and chills, says the U.S. Department of Agriculture (USDA).

    Warning

    • Salmonella infections may be harmful in young children, pregnant women and people with impaired immune systems.
