Which of the following is not a requirement for items intended for human consumption?

The requirement for items intended for human consumption focuses primarily on health and safety standards. Items must be properly labeled to provide essential information to consumers, such as ingredients, nutritional content, and potential allergens. Being free from contaminants is crucial, as contamination can pose significant health risks. Additionally, conformity to NSF 61 ensures that materials used in plumbing systems that transport drinking water meet necessary health standards, safeguarding consumer health.

While aesthetics can be an important factor for consumer preference, it is not a regulatory requirement concerning safety or health. Therefore, items being aesthetically pleasing does not fall under the critical requirements defined by health codes, making it the correct choice in this context.
