    Notes: A survey assessed the handling of shell eggs and processed eggs from purchase until serving to potentially vulnerable people in care homes, acute hospitals, handicapped institutions, and crèches (i.e. nurseries). In 94% of the institutions shell eggs are consumed at a weekly average of 1.1 ± 0.3 eggs for each person. In 52% of the institutions egg products are used. The shell eggs are held on average at 6.4C for 1–2 weeks. The questionnaire listed a series of egg dishes, which were classified afterwards in three risk categories. Of the high-risk dishes, shell eggs are particularly used for addition to mashed potatoes, for preparing soft-boiled eggs and eggs sunny-side-up and for inclusion in hot sauces. Of the medium-risk dishes, shell eggs are used for preparing scrambled eggs and omelets. When egg products are bought next to shell eggs, relatively less high-risk dishes and more low-risk dishes on the total dishes were made from shell eggs. Thus, egg products are purchased on a rational base. The distribution of storage temperature, storage time and preparation frequency of high-risk meals were combined using a Monte Carlo resampling technique, which indicated that the majority of the samples (98.5%) fell into a low-hazard category.

    Notes: A survey of parents of higher education college students assessed the purchasing behavior, storage conditions and consumption of hen eggs in the household, to quantify microbiological unsafe handling. Analysis of the questionnaires indicates an average consumption of 6.4 eggs per month, which are kept at an average temperature of 9.7C for 2 weeks. An additional spot check showed that the interviewees probably underestimate the keeping temperature. The questionnaire also listed a series of egg dishes, which were afterwards categorized according to risk. The distributions of storage temperature, keeping time and type of dish were combined using a Monte Carlo resampling technique, which resulted in a hazard distribution. This distribution showed that the majority of the samples (98.2%) fell into a low hazard category.

    Notes: A model clarifier was designed using conventional methods for the surface calculation and an alternative pathway for the determination of the height and constructed accordingly. In addition, a new approach was used to evaluate the necessary scraper speed in comparison to full-scale clarifiers. Scaling effects were taken into account. The model clarifier was first tested by tracer experiments. Conductivity measurements were used for the clarification zone, whereas the thickening zone was tested using pyrene as an organic tracer compound. Finally, the behaviour of the model clarifier was compared with a full-scale settler. The results indicated that operation of the model clarifier was representative of full-scale behaviour, except for severe overloads. Hence, the small-scale clarifier qualified as a model for small-scale studies and could be installed on large-scale plants to monitor more transparently plant performance and sludge behaviour
