Question
The bright fluorescent sheen on cold cuts left in the refrigerator too long is caused by Pseudomonas fluorescens.
Solution
This statement discusses the reason for the bright fluorescent sheen observed on cold cuts that have been stored for an extended period in the refrigerator. The sheen is attributed to the bacterium Pseudomonas fluorescens, which is known to produce a pigment that fluoresces under certain conditions.
Common Understanding
- Pseudomonas fluorescens: This is a type of bacteria commonly found in the environment, including soil and water. It can spoil food, particularly meat and dairy products.
- Fluorescent Sheen: The sheen is a visible sign of bacterial growth, often indicating that food may no longer be safe to consume.
- Food Safety: Cold cuts with visible signs of spoilage should not be eaten as they can pose health risks.
In essence, the presence of Pseudomonas fluorescens is an indicator of spoilage in cold cuts due to prolonged storage in the refrigerator.
