As well as older processing methods such as high pressure, thermal treatment and ionizing radiation, Lawrie also explores newer technologies, such as DNA profiling.
"Greater understanding of animal DNA allows processors to analyse toxins produced by pathogenic micro-organisms", he says. It can also provide reliable ways of identifying a species, even in severely processed meat products," he added.
The testing of DNA has been made easier in recent times thanks to the emerging technologies of nanotechnology and bioinformatics, two molecular-level sciences both examined in the guide.
