Final answer:
Sealing cracks and seams in the kitchen is vital for food safety as it prevents pathogen entry and minimizes freezer burn by reducing air circulation that can degrade frozen food quality.
Step-by-step explanation:
All cracks or seams should be sealed up in the kitchen to maintain hygiene and to prevent the entry of pathogens that can contaminate food surfaces and lead to foodborne illnesses.
Sealing cracks and seams also helps to minimize freezer burn by preventing air circulation, which can dehydrate the surface of frozen food and lead to quality degradation.
The expansion and contraction of materials due to thermal stress can create or exacerbate these openings, so it is crucial to ensure they are properly sealed to maintain kitchen integrity and food safety.
Cracks or seams in the kitchen should be sealed up to prevent the effects of thermal stress. Thermal stress occurs due to the expansion and contraction of materials when exposed to temperature changes. If cracks or seams are not sealed, they can allow for differential contraction and stresses that can lead to damage.
