This introduction is followed by a discussion of different practical techniques for selecting a sample. The third part discusses sampling in relation to a number of different survey designs, with special reference to the question of sample size. Finally, we examine a number of special situations that require different sampling approaches.

The consumer’s demand for high food-safety documentation and quality might influence the extent of surveillance; for example, there may be markets for Salmonella-free chicken in some countries. BSE in cattle is a recent example of how the human health risk has played a key role in the implementation of MOSSs throughout Europe. Some interventions may be unacceptable to the public in some countries but not in others. For instance, 1.
