So many different answers & opinions about after how long, how many hours must past before the equipment needs to be re-cleaned and sanitized in a dairy processing facility.( ice cream) My question is this true? Do we have to re-clean & re-sanitize after a certain amount of time when the equipment is not being used? What they do here is; a final deep down clean on Friday, off Saturday then come back Sunday night to re-clean & sanitize. I asked why they re-clean and re sanitize and the reply, that's what they always do. Is there an ordinance / clause stating this? or is this at the companies will? Any direction would be appreciated.
