From the Guidelines

Preventing Salmonella infection primarily involves proper food handling and hygiene practices, and treatment typically involves staying hydrated and, in severe cases, antibiotics such as ciprofloxacin, azithromycin, or trimethoprim-sulfamethoxazole, as recommended by the most recent guidelines 1. To prevent Salmonella infection, it is essential to:

  • Wash hands thoroughly with soap and water before handling food, after touching raw meat, and after using the bathroom
  • Cook foods to proper internal temperatures: 165°F for poultry, 160°F for ground meats, and 145°F for whole cuts of meat
  • Avoid cross-contamination by using separate cutting boards and utensils for raw meats and ready-to-eat foods
  • Refrigerate perishable foods promptly and don't consume raw or undercooked eggs or unpasteurized dairy products For treatment, most healthy adults recover without specific treatment within 4-7 days by staying hydrated with water, clear broths, and electrolyte solutions. Severe cases may require antibiotics, and hospitalization with IV fluids may be necessary for severe dehydration, especially in high-risk individuals like infants, elderly people, and those with compromised immune systems, as suggested by 1 and 1. It is also important to avoid anti-diarrheal medications as they can prolong the infection by preventing bacteria from being expelled, and antibiotics are prescribed selectively as they can sometimes prolong the carrier state and contribute to antibiotic resistance, as noted in 1 and 1. Additionally, typhoid vaccination is recommended as an adjunct to hand hygiene and the avoidance of high-risk foods and beverages for travelers to areas where there is moderate to high risk for exposure to Salmonella enterica subspecies enterica serovar Typhi, people with intimate exposure to a documented Salmonella Typhi chronic carrier, and microbiologists and other laboratory personnel routinely exposed to cultures of Salmonella Typhi, as recommended by 1 and 1.

From the FDA Drug Label

Typhoid Fever (Enteric Fever) caused by Salmonella typhi.

The prevention and treatment methods for Salmonella infection are not fully described in the provided drug label. However, it is mentioned that ciprofloxacin can be used to treat Typhoid Fever caused by Salmonella typhi.

  • The label does not provide information on how to get a Salmonella infection.
  • For treatment, ciprofloxacin may be used, but it is essential to perform culture and susceptibility tests before treatment to determine the susceptibility of the bacteria to the drug.
  • It is crucial to use ciprofloxacin only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria to reduce the development of drug-resistant bacteria 2.

From the Research

Prevention Methods for Salmonella Infection

  • Proper handling and cooking of food, especially poultry and eggs, can help prevent Salmonella infection 3
  • Avoiding close contact with patients experiencing diarrhea and animals can reduce the risk of developing salmonellosis 4
  • Improving animal handling practices and promoting better hygiene in both the environment and personal habits can help reduce Salmonella infections 4
  • Using probiotic micro-organisms has shown antagonistic properties against Salmonella and other enteropathogenic bacteria, and may be a potential alternative treatment 3

Treatment Methods for Salmonella Infection

  • Azithromycin and ciprofloxacin are commonly used to treat Salmonella infections, with azithromycin being the preferred choice due to its lower resistance development 5
  • Ceftriaxone is also effective in treating Salmonella infections, especially in patients with severe disease 5
  • Treatment with azithromycin and ciprofloxacin has been shown to reduce mortality and morbidity in patients with Salmonella infection 6, 7
  • However, the use of antibiotics can lead to antibiotic-resistant strains of Salmonella, and alternative treatments such as probiotics are being explored 3

Antibiotic Resistance Patterns

  • Salmonella isolates have shown high resistance rates to ampicillin and tetracycline, and moderate resistance to ciprofloxacin 4
  • The use of antibiotics can lead to the development of antibiotic-resistant strains of Salmonella, making treatment more challenging 5, 4
  • The prevalence of culture-confirmed Salmonella serovars among humans and animals is significantly high, with many isolates showing resistance to three or more classes of antibiotics 4

Risk Factors for Salmonella Infection

  • Close contact with patients experiencing diarrhea and animals can increase the risk of developing salmonellosis 4
  • Poor hygiene and animal handling practices can also increase the risk of Salmonella infection 4
  • The risk of developing salmonellosis is higher in individuals who come into contact with those experiencing diarrhea or who handle animals 4
