Contamination of spices with pathogens has been reported worldwide, and
Salmonella might result in foodborne infections. In this study, we investigated the survival of
Salmonella in black pepper and red pepper, and the growth of the surviving
Salmonella in cooked food.
Salmonella Enteritidis,
Salmonella Weltevreden and
Salmonella Senftenberg were inoculated into spices, and their survival during storage was examined. In black pepper,
S. Enteritidis was no longer viable after storage for 28 days, but
S. Weltevreden and
S. Senftenberg remained viable. In red pepper,
S. Weltevreden and
S. Senftenberg survived for 28 days although
S. Enteritidis was not viable after 7 days.
Salmonella Weltevreden and
Salmonella Senftenberg were inoculated into cooked food, and their survival during storage was determined. In potato salad, egg salad, namul and kimchi as cooked foods, both pathogens grew at 30°C, but not at 10°C. Our results indicate that cooked food should be stored at low temperature after addition of spices, such as black pepper and red pepper, following the cooking.
