"You've probably seen the NSF and UL labels in your restaurant or commercial kitchen before. And you probably already have an idea what these organizations do and what that label means. But fully understanding what the NSF and UL do to make sure restaurant equipment and tools meet food and personal safety standards is worth your time, so here's a brief explanation:
NSF International (formerly known as the National Sanitation Foundation) is an independent, non-profit organization that certifies food service equipment and ensures it is designed and constructed in a way that promotes food safety.NSF is internationally recognized and most food service equipment is NSF certified. What does that certification mean?
Equipment certified by the NSF must complete the following process:
The facility where the product is made is thoroughly audited by an NSF representative. This ensures the product is constructed in a sanitary manner and that the standards for sanitary design elements are actually met during construction and assembly.
A physical evaluation of the product is carried out to ensure it meets food safety standards. Testing and evaluation is done on the materials used to make the product to make sure they meet standards. The facility and product must also undergo annual follow up audits to maintain certification. NSF certified products have therefore passed a stringent set of evaluations to ensure food safety requirements and standards are met.
Some common food service equipment that is certified by the NSF include: commercial dishwashers, cooking, hot holding, and transport equipment, dispensing freezers, commercial refrigerators and storage freezers, automatic ice making equipment, and food and beverage dispensing equipment. Many restaurant and commercial kitchen utensils and cutlery also get NSF certification.
As a restaurateur, purchasing NSF certified equipment and small wares ensures that your business is promoting food safety. The power of NSF’s reputation means that most equipment you buy is already certified, but understanding what that certification means is important when you look to buy new equipment or during your next health inspection."

fwiw, .........every year we buy 5 gallons of honey from a local beekeeper. Last year, they delivered the honey in Home Depot paint buckets. I looked at the recycle number on the bottom, but we still transferred the honey out of the HD buckets and into glass jars right away.
A restaurant I used to work at used to use plastic trash bags to wrap large food items for the cooler and freezer, until the health inspector pointed out that trash bags do not have to list any chemicals that may be in the plastics, including deodorizers or mold inhibitors.
I really question plastics that are used for food service that are not food service plastics!
