Sanitation Certification Practice Test

What kind of packaging methods are generally linked to the need for a variance?

1. Regular plastic wrap

2. Foil wraps

3. Reduced Oxygen Packaging and MAP

4. Standard cardboard boxes

The correct answer is: Reduced Oxygen Packaging and MAP

The correct answer is linked to Reduced Oxygen Packaging (ROP) and Modified Atmosphere Packaging (MAP) because these methods create an environment with lower oxygen levels, which can inhibit the growth of certain microorganisms but also poses unique food safety risks. Because of these risks, using these packaging techniques often requires a variance or special permission from local health authorities to ensure that food safety standards are upheld. These methods can allow for the growth of harmful bacteria if not handled properly, so establishments must demonstrate a clear understanding of necessary safety measures, such as temperature control and monitoring oxygen levels, when opting for these packing methods. This process ensures that both food quality and safety are maintained, hence the need for a variance. Other packaging methods, like regular plastic wrap, foil wraps, and standard cardboard boxes, do not significantly alter the oxygen levels surrounding the food and thus do not generally require the same level of regulatory oversight or variance. Regular plastic wraps and foil wraps typically maintain a similar atmosphere as air exposure, while standard cardboard boxes are not intended for long-term storage of food items in a controlled atmosphere.
