Which statement about surfaces of equipment or utensils is true?

• A. Joints and seams in the food-contact zone must be sealed and smooth
• B. Surfaces should be rough to improve grip
• C. Surfaces should impart odors to food
• D. Surfaces should absorb moisture

Answer: (A)

Surfaces that touch food must be smooth and sealed to be cleanable and sanitary. When joints and seams in the food-contact zone are smooth and tightly sealed, food particles and moisture are less likely to get trapped, making cleaning and sanitizing more effective and reducing the risk of bacterial growth. A smooth, non-porous finish also minimizes niches where debris can accumulate and helps prevent cross-contamination.

Rough surfaces, by contrast, are harder to clean and provide spaces where microorganisms can thrive. Surfaces that impart odors or absorb moisture can transfer undesirable smells to food and create environments that support microbial growth and corrosion, both of which compromise safety. In practice, equipment designed for food contact uses materials and construction that avoid gaps, cracks, and porous areas—think seamless welds, tight joints, and non-porous finishes—so sanitation steps work reliably.

So the statement about joints and seams in the food-contact zone being sealed and smooth is the best choice because it directly supports effective cleaning, sanitizing, and overall food safety.
