Food Storage Best Practices Flashcards

What is freezer burn and how can it be prevented?

Answer: Dehydration and oxidation of food surface due to improper packaging, prevented by using moisture-proof, airtight wrapping and minimizing storage time

Freezer burn occurs when food is exposed to cold, dry air in the freezer, causing surface dehydration and oxidation. While not a safety hazard, it reduces quality. Prevention involves airtight, moisture-proof packaging and removing excess air.

How should leftover food from a buffet be handled at the end of service?

Answer: Discard potentially hazardous foods that have been in the temperature danger zone; foods maintained at proper temperatures can be quickly cooled and stored with new date labels

Buffet foods must be evaluated based on temperature maintenance. PHFs that dropped into the danger zone for more than 2 hours must be discarded. Foods maintained at proper temperatures can be rapidly cooled, properly stored, and labelled with new dates.

Why should raw meats never be stored above ready-to-eat foods, even if the meat is properly wrapped?

Answer: Wrapping can leak, tear, or fail, and condensation on packages can carry bacteria downward onto ready-to-eat foods

Even well-wrapped raw meat can leak through tiny tears, loose wrapping, or condensation on the package exterior. If positioned above ready-to-eat foods, these drips introduce pathogens. The bottom-shelf rule provides a failsafe.

What is the recommended humidity level for dry storage and why?

Answer: 50% to 60% relative humidity to prevent mould growth while maintaining product quality

Relative humidity of 50–60% is optimal for dry storage. Higher humidity promotes mould growth, attracts pests, and causes clumping of powders. Too low humidity can cause cracking and drying of some products.

A food handler needs to store a large batch of cooled soup. What is the proper container choice?

Answer: Several shallow, food-grade containers no deeper than 7.5 cm (3 inches) to allow rapid and even cooling during refrigeration

Shallow containers (no deeper than 7.5 cm/3 inches) maximize surface area, allowing heat to dissipate quickly and evenly. Deep containers cool too slowly in the centre, keeping food in the danger zone and promoting bacterial growth.

What are the risks of overstocking a refrigerator?

Answer: Overstocking blocks air circulation, creates uneven temperatures, makes FIFO rotation difficult, and can push foods past their use-by dates due to poor visibility

An overstocked refrigerator restricts airflow, leading to warm spots where bacteria can grow. Items get lost behind other products, making FIFO rotation difficult and increasing waste. Proper organization with space between items is essential.
