The resin is safe for food contacting the surfaces, for example if used as a charcuterie board or counter top. The resin would not be safe if used as a cutting board, dinner plate, or inside a mug.

The resin I use is from Mas Epoxies. Here is a link to their FAQ, where the have a section on food safety: masepoxies.com/table-top-pro-epoxy-faq

They also provide the following information: “MAS Table Top is not FDA approved for direct food contact. To our knowledge, no manufacturer is selling a FDA approved epoxy resin system.  Some manufacturers may claim “FDA complaint”, “meets FDA guidelines”, etc. – this is not the same as FDA approval.  These are largely marketing claims that have not necessarily been substantiated.  That said, we’ve made many table/bar tops with our product and personally feel comfortable if the tabletop incidentally contacts food (like dropping and being picked up), but we wouldn’t use it to coat a food prep surface or a mug where the food or someone’s mouth will have direct and continuous exposure.”
