We have long used color-coded plastic cutting mats at our house to prevent cross-contamination between meats and vegetables. The first set was plastic and then we had silicone mats from Casabella that lasted several years. When they got too scratched up, we replaced them with Progressive Prepworks Flexible Color-Coded Chopping Mats.
It’s a typical set of four 11 x 15-inch, color-coded plastic mats. There’s a red mat for beef, yellow for chicken, blue for fish, and green for vegetables. Each mat is marked with an icon in case you’re color-blind. Progressive says they’re dishwasher-safe and won’t dull your knives. A set runs about fifteen bucks and includes two smaller (7½” x 11”) clear mats. All mats have a hole along a short side for hanging them on a hook.
Our mats were already slightly curled when we unpacked them. Progressive says that’s a selling point: supposedly this lets your pour the contents from the mat. In this case, the curl kept getting tighter the whole time we owned them, to the point that they became useless except for heavy items. All six curled across the short dimension so tightly that the center of the larger mats about 3” off the counter if nothing was on it. A couple of the mats cracked at the hole where they were hung.
These are cheap, brittle plastic. After just a couple of months, we threw them away and replaced them with a slightly more expensive but far more useful version.
