Hi, I have just taken over management of a small food micro lab with very basic procedures. We test for salmonella, E coli, Coliforms, S aureus and of course TVC. I need to put positive and negative controls in place and have chosen and ordered the relevant organisms. They come in form of a freeze dried disc.
Please can anyone give me some help and advice on how to culture and grow the micro-organisms - what media would you recommend? they will be used for media quality control and for process control.
