NSF Lighting and food process lighting defective guide 2021

Nowadays, more and more customers are asking “Do your LED lights have the NSF certification? Our customer requires the NSF certificated lighting to use in the food-safe processing area”. Based on the questions and feedback we collected from the market and customers. Today, we would like to spend some time discussing the NSF certification and NSF rated lighting products.

“Lighting requirements have been in effect since 1976 and, as detailed in the 2017 FDA Food Code, any lighting or other equipment used in a facility where food is prepared, processed, or served must meet NSF, ANSI, or an equivalent standard for food safety,” he said. “If not, it could lead to a violation, removal of the lights, or could even prevent a food service facility from opening during the initial plan review until the lighting is brought into compliance.”

Confirmed by Vito Palazzolo, MSPA, RS-REHS, CP-FS, and Manager of Food Safety and Industry Relations for the 50,000-member National Restaurant Association based in Chicago, IL, it’s the law

ONE: Why needs NSF lighting?

Food processing applications can be extremely challenging for light fixture products, they ask higher standard than any regular lighting products.

Since food processing facilities endure high-pressure washdowns using corrosive cleaning solutions and are exposed to steam, grease, oil and fluctuating temperatures, the lighting installed in these spaces need to be able to endure these tough conditions on a day-to-day basis. At the same time, they must contribute to the maintaining of a clean environment while safely lighting up the workspace. This is why more food processing factory ask to provide the NSF rated lighting fixture products.

TWO: What is NSF certification?

NSF LED Vapor proof

NSF International was founded in 1944 as the National Sanitation Foundation to help standardize sanitation and food safety at a time when the United States had no national sanitation standards. As NSF expanded services beyond sanitation and became a global public health and safety organization, we changed our name to NSF International in 1990.

From the beginning, NSF set a course to create independent standards and product testing programs to help improve overall public health. NSF has more than 140 currently active public health standards and independent testing protocols. They address products ranging from home water treatment systems to kitchen and household appliances to dietary supplements to sustainable flooring and furnishings.

Today, NSF International is a global organization offering services in more than 170 countries. Headquartered in Ann Arbor, Michigan, we remain committed to protecting and improving human health worldwide. We are a Pan American Health Organization/World Health Organization Collaborating Center on Food Safety, Water Quality and Indoor Environment.

THREE: What is NSF Certificated lighting?

NSF International provides lighting certifications for manufacturers whose products are used in industries where sanitation, structural integrity, and low air pollutant levels are essential. NSF-approved lighting products typically have designs and production methods intended to withstand abuse and avoid contamination of the area where the light is installed.

The NSF has approved a variety of lamps and fixtures for these applications. NSF certification provides a way for purchasers and consumers to know that a certain lighting product is of the highest quality.

NSF-certified lighting products are typically designed to reduce breakage and protect occupants from injury or contamination. They also have features designed to ensure the light’s performance when faced with contaminants often found in these environments.

NSF has defined standards based on area conditions and on the extent of direct contact with food products. The NSF standard that relates to food and beverage lighting products, referred to as NSF/ANSI Standard 2 (or just NSF 2), organizes plant environments into three zonal categories: Non-Food Zone, Splash Zone and Food Zone (Table 1).

Each zone reflects environments ranging from areas such as food storage, where there is no direct contact with food products and no high-pressure wash-downs; wet-processing areas that require high-pressure wash-downs but where there is no direct contact with food; and areas where the product comes into direct contact with food.

Since lighting products do not come into direct contact with food, only the NSF guidelines for Non-Food Zone and Splash Zone usually apply. LED lighting manufacturers seeking NSF-2 certification for their products must ensure that a product’s physical design, the materials used, and the manufacturing processes employed all comply with NSF standards according to the relevant zone.

FOUR: Benefits of NSF rated lighting?

Everything in the food and beverage manufacturing industry has to be tested and approved for safe use around the products we consume, even the lighting. But understanding the different certifying bodies and requirements that light fixtures are expected to meet can be confusing. And, not to mention the special conditions required of the facility itself. The three most important concerns when it comes to food processing are to prevent:

  • Contamination
  • Bacterial growth
  • Food spoilage

Because of these concerns, even the lights used for food processing facilities must have a high level of protection. This includes protection against airborne dust, effluents, steam, mist, water, oils, grime, and cleaning solvents. Finding lighting that meets the strict requirements of food processing plants and helps prevent these concerns can be challenging.

LEDs are designed, they should decrease thermal damage and degradation in food caused by lighting. This makes them suitable for cold storage applications.

Recent research has shown LEDs can preserve or improve the nutritive value of food in post harvest stages, as well as help to reduce fungal infections caused by other light sources. In addition to this, LED lights can be used in conjunction with photo-catalysts or photo sensitizers to inactivate pathogenic bacteria in food.

LEDs produce very little heat as a byproduct of creating light. They are not affected by cold temperatures, making them a good choice for food storage and inside food processing facilities. Thanks to their long expected lifespan and durability, NSF certificated lamp help facilities reduce lighting bills and maintenance costs.
