Salmonella can contaminate onions through various means, primarily through the soil, water, or during the harvesting and processing stages. In fields where onions are grown, the bacteria can be present in the soil due to animal feces or contaminated irrigation water. If onions come into contact with contaminated soil or water during growth, the bacteria can adhere to their surface. Additionally, during harvesting and processing, if proper hygiene practices are not followed, such as washing hands, equipment, and surfaces thoroughly, there’s a risk of transferring Salmonella from the environment to the onions. Once contaminated, Salmonella can survive on the surface of onions and may even penetrate into the layers of the onion bulb, making it important to handle and prepare onions safely to prevent foodborne illness.
