ABSTRACT

Selina majored in Food Science and graduated with a good record. She decided to stay on for her master’s degree and chose to specialize in food microbiology. As part of her degree, she is conducting original research under a member of the faculty in the Food Science Department. She became interested in how Salmonella can get stressed under certain conditions (often when nutrients are unavailable). Salmonella cells can be injured and difcult to detect. Thus, the food being tested for Salmonella may show no signs of its presence but can still be quite dangerous. Thus, to detect the presence of Salmonella, an enrichment medium must be used to culture an extract of the food sample to help recover any injured cells. Selina’s work is to determine at what level a specic nutrient is required to improve recovery.
