CIEH Level 4 Awards in Food Safety
That is a brilliant resource Simon. I'd definitely have a look at this Kel; on the right hand side are all of the assignment marking sheets which your trainer will use. That's an excellent guide for what the trianer will be expecting.
Looking through, it looks like you still have to submit two assignments. Depending on where you work, the Food Safety Management Procedures looks meaty to me, cleaning and disinfection could be useful because there are so many places to collect info, e.g. audit of the process, procedures, micro historical data, training records, chemical concentration checks, talking to staff etc. I did the personal hygiene one and again, it's a meaty subject with loads to look at. I also did pest control because I knew the site I was working on at the time had pest control problems. (I concluded they were not fulfilling their legal obligations in the end which got me 99% and an angry Operations Manager!)
I would say if you work in high risk or high care your choices are very wide because so many of those topics will impact on your process. If you work in ambient food and a simple process, I'd go towards things like personal hygiene / procedures / cleaning or pest control because they are the topics which impact on every industry and also are multi-faceted. I would steer clear of chemical contamination unless there is a major risk in your industry because you can cover a lot of that topic within cleaning and you risk running out of things to say.
Do you know which ones you want to do? If so, post them on here and I'll brain storm some ideas for you on where to start if you like?
