Abstract:
... Microbial food safety sampling in the food industry is generally based on single sampling schemes, with the results dictating the acceptance/rejection of the entire food lot. Resampling plans are generally only used to discern quality of ingredients or food items where food safety is not part of the evaluation. This paper developed a Bayesian model to quantify the uncertainty in the concentration ...
