Soil Sampling Standard Operating Procedure: August 1997 ...archive.epa.gov
Potential problems with soil sampling include cross-contamination of samples and im proper sample collection. Cross-contamination problems can be eliminated or minimized through the use of dedicated sampling equipment and bottles. If this is not possible or practical, then decontamination of sampling equipment is necessary.
Safer Food Better Business For Childminderswww.food.gov.uk
Food also needs protecting from ‘chemical contamination’ (where chemicals get into food, e.g. cleaning products) and from ‘physical contamination’ (where objects get into food e.g. broken glass). Good cleaning and handling practices can also help manage the risk of cross contamination from allergens.

Coliform Bacteria and Drinking Waterdoh.wa.gov
probably environmental and fecal contamination is unlikely. However, if environmental contamination can enter the system, pathogens could get in too. It is important to find and resolve the source of the contamination. Fecal coliform bacteria are a subgroup of total coliform bacteria. They exist in the intestines and feces of people and animals.
Reducing Contamination Risks of Compressed Air in Food ...www.foodengineeringmag.com
air is invisible. It leaves no visible trace where it contacts the food, other food contact surfaces, or the packaging. Without adequate hurdles and physical barriers in place the microbial, particulate, and (in some cases) compressor oil contamination is left behind after the air dissipates. Some examples of direct and indirect contact points are:
