Im in the process of doing all the Health permits, Commissary etc. I was ask today from the Health Department if my smoker was NSF approved. I bought a Lang 84 and to make it better I had the grates made with stainless steel instead of regular metal. Im going to be taking it down in 2 days to get my smoker approved. I'm hoping I have no problem. Ive seen many bbq catering companies use smokers like mine. I know some have Southern Pride on trailers but many use real wood smokers such as the Lang. Has anyone ever had a problem with the Heath Department when it comes to commercial smokers for catering?
