ABSTRACT
Laboratory procedures are standard practices that are followed by laboratory scientists of the same discipline. Many laboratory procedures are concerned with safety, handling of hazardous materials, record-keeping and reporting requirements for results of experiments. Several reference manuals and compendia are available that describe the specific laboratory procedures used to detect and isolate filth from foods. A microanalytical laboratory requires little in the way of elaborate equipment or facilities. A basic chemistry laboratory environment is suitable. The laboratory must have chemical fume hoods and standard benchwork but with a relatively deep sink for sieving operations. Every microanalytical entomology laboratory must have procedures in place to guard against contamination from microscopic filth. Two types of contamination can occur: extrinsic contamination and cross-contamination. Each laboratory should consult their chemical hygiene officer or consultant about the proper management of the chemical byproducts of these or any other analyses performed by the laboratory.
