Salmonella Food-Poisoning Pictures: Salmonella Food Sources, Symptoms, and Treatment

What are symptoms and signs of Salmonella poisoning?

  • Symptoms of Salmonella poisoning usually begin 12-72 hours after infection.
  • Diarrhea, abdominal cramping, and fever are common symptoms.
  • The diarrhea is typically loose and not bloody. Nausea, vomiting, headache, and muscle aches may occur.
  • The symptoms usually go away on their own after four to seven days.

Is Salmonella contagious?

  • Many of the members of the bacterial genus Salmonella are contagious.
  • Salmonella food poisoning is usually acquired from eating contaminated foods. It is possible to spread the infection to others through fecal-oral contamination, meaning that fecal material contaminates the hands of an infected person who then contaminates foods that are consumed by others.

Those with Salmonella infection can be contagious for days to weeks, even after symptoms have disappeared.

What kinds of doctors treat Salmonella food poisoning?

Salmonellosis may be treated by primary-care specialists, pediatricians, emergency-medicine specialists, or internal-medicine specialists. In severe or complicated cases, other specialists may be consulted, including gastroenterologists or critical-care specialists.

How do physicians diagnose Salmonella food poisoning?

Many infections can cause similar symptoms, so diagnosis of Salmonella infection requires identification of the organism in a stool sample from the affected person. Specific tests can be done to identify the exact type of Salmonella responsible for an infection.
