f) Return swab to test-tube, at the same time breaking off part of wood touched by  ngers. The swab should be examined immediately. If this is not possible any delay shall be kept to a minimum and the tube with the swab shall be cooled quickly to not be more than 4oC and maintained between 0oC and 4oC until examined, preferably within 36 hours.
Packaging Material
This guide does not deal with packaging materials brought in new from the outside (paper, cartons, plastics, etc.) but only with re-usable packaging materials.
For re-usable packages (meat crates), visual monitoring of the cleaned containers is necessary as well as examination of a certain part of the containers.
Usually the swabbing method is used for sampling of meat crate surfaces. Directions are as given in 3.2.1.6.1.
Air
Sampling for airborne microorganisms in processing plants involves collecting samples in air pathways by which organisms may be introduced into processing equipment. Samples may be taken as follows:
a) At openings in equipment subject to potential contamination from organisms transported by air currents.
b) At selected points for testing the quality of air in the room, for example where products are packed.
c) In processing areas where employees are concentrated.
turbulence during operating hours, sampling by volumetric be more effective and dependable than use of the
technique.
