Refer to CCP 2 UV sterilization – UV intensity in 16,000 micro-watt/ sec in HACCP Plan summary (H5-1, rev 0, page 5/7). And a warranty card from machine supplier, named Dai Truong Nam Technology Co., Ltd. on 20/3/2013. (Warranty card no. A012013) is observed. The company’s logo is stamped and signature is observed on it. It is defined that its lamps working life time is one year to maintain UV intensity in 16,000 microwatt /sec.
The counter is set 365 and reduced while these UV lamps have been installed and used since 2013. It is limited evidence to demonstrate how CCP2 monitoring officer can monitor and know their actual end date.
(Note: This finding is raised in minor level because UV sterilization machine is a new machine and lamps. This is low risk to impact food safety. In addition, external testing results of their products are demonstrated that they are no pathogen contamination or survival.)
