Abstract
Although the U.K. food sampling network is well developed, the number of food
poisoning incidents continues on an upward trend. Existing food sampling
programmes used by the U.K. local authorities, where they exist, operate in a 'hit
or miss' fashion. The use of small sample sizes is also common. This study
examined the costs and benefits of current sampling programmes, and proposes
an alternative using statistically validated approach to food sampling. Because
sampling involves errors due to uncertainties and variations, a statistically
validated sampling model was developed in an attempt to determine suitable
sample sizes under various sample proportions that would also satisfy good
normal approximation in order to reduce margin of error to a minimum.
However, the model illustrated that the use of small sample size
