Question

how does salmonella spread to humans?

Explanation:

Salmonella spreads to humans mainly through: 1) Ingesting contaminated food (e.g., undercooked poultry, eggs, raw fruits/vegetables with fecal contamination). 2) Contact with infected animals (pets, farm animals) or their environments (e.g., handling reptiles then touching mouth). 3) Person - to - person via fecal - oral route (poor hygiene after contact with infected individuals).

Answer:

Salmonella spreads to humans via ingesting contaminated food (undercooked poultry/eggs, contaminated produce), contact with infected animals (or their environments), and fecal - oral person - to - person transmission (poor hygiene after contact with infected individuals).
