Personallly I think that the minimal requirements are a weighting balance, 2 incubators, stomacher, microscope, vortex, an autoclave and a water bath. From there on the sky is the limit! So as to be complete you need at least one more incubator, a dry sterilization unit, a laboratory blender, a filtration apparatus, preferably manifold, a laminar flow, an anaerobic system, a colony counter and a spiral platting system. These should be sufficient for most ISO methods. Concerning in house methods (e.g. PCR) the appropriate equipment is also needed.

Hi, about incubators. Food laboratories usually need four incubators with four different kind of temperatures. 25 for molds and yeasts, 30 for mesophiles, 37 for pathogens, and 55 for thermophiles.
I did not see anyone mention the need for a microcentrifuge or clean bench; I strongly recommend both to conduct reliable research or quality analyses. Furthermore, a spectrophotometer with cuvettes would be a strong tool as well for food quality surveillance with respect to microbial growth.
