What is the minimum mesh size for screening material used to protect openings from insects?

• A. 12 mesh to the inch
• B. 16 mesh to the inch
• C. 14 mesh to the inch
• D. 18 mesh to the inch

Answer: (B)

The minimum mesh size for screening material used to protect openings from insects is 16 mesh to the inch. This specification is critical for ensuring that the screening is fine enough to prevent insects like flies, mosquitoes, and other pests from entering food service areas, which helps maintain a safe and sanitary environment. A mesh size of 16 per inch means there are 16 openings in one linear inch of the material, which provides a barrier that is effective against a wide range of insect sizes. Using a screen with a mesh size larger than this may allow smaller insects to pass through, potentially leading to contamination of food and surfaces, as well as contributing to pest infestations. Conversely, while screens with mesh sizes of 12, 14, or 18 may provide varying levels of protection, 16 mesh is the established minimum standard recognized in food safety guidelines, ensuring a reliable level of protection against common flying insects encountered in a food service setting.
