What is salmonella?
Salmonella is a group of bacteria that is one of the most common causes of food poisoning in the US. It usually spreads through food, and eggs and poultry are classic sources because the bacteria can be inside an egg that looks perfectly normal. Cooking eggs until both the white and yolk are firm kills it.

Treatments & Vaccines in Development

Most salmonella cases clear up on their own with rest and fluids. Antibiotics are held back for severe or high-risk illness, and there is no vaccine for the egg-borne type. Here is what treatment looks like.

Fluids and rest (supportive care)Supportive care
First-line for most people
Standard of care

Most healthy people with salmonella recover on their own in about a week without specific treatment. The main thing is staying hydrated, since the danger from diarrhea and vomiting is fluid loss. Antibiotics are not recommended for a typical case because they do not help much and can prolong how long the bacteria are shed.

Antibiotics (severe cases)Antibiotic
For severe or high-risk illness
Generic: ciprofloxacin, azithromycin, ceftriaxone

Antibiotics are reserved for people with severe illness or those at higher risk of the infection spreading beyond the gut, such as infants, older adults, and people with weakened immune systems or sickle cell disease. In those cases drugs like ciprofloxacin, azithromycin or ceftriaxone are used and can be life-saving.

CDC clinical guidance
Salmonella vaccineVaccine
None for this type

There is no vaccine for the non-typhoidal Salmonella that causes food poisoning like this outbreak. A vaccine exists for typhoid fever, which is a different Salmonella, but it does not protect against egg-borne Salmonella. Prevention comes down to food safety: cook eggs until firm, refrigerate promptly, avoid recalled products, and wash hands and surfaces.
