Two separate taxa, or races, of elephants exist in Africa today: the savannah elephant, which is well known and has been studied and valued by the international tourist trade for decades, and the diminutive forest elephant, which until recently has remained in obscurity beneath the trees. However, before we get too carried away with horrific idea that elephants may well become extinct there is another side to this. Combine this deliberate destruction with increased land use change and habitat transformation by private enterprise, international aid and government expansion across Africa and these magnificent beasts are still under threat even within the national parks and other protected areas set aside for them. It’s not news that elephants are endangered for literally thousands of years ivory has driven hunters to kill these magnificent beasts. Genstat has excellent procedures for performing models of this kind and for extracting model coefficients in a form that can be used to make a range of policy-relevant inferences. These estimates are used to prioritise biotoxin sampling activity around the shores of the UK, indicating where, and at what times of year, the level of sampling should be raised, and also where and when it can be reduced. The FSA uses Hierarchical Generalized Linear Models to model the probability of elevated levels of naturally occurring biotoxins in shellfish. probabilistic assessments of risk that allow for variability and uncertainty in some of the key input variables. It has the flexibility to perform more complex modelling when required: e.g. Genstat provides excellent tools for the necessary data import, indexing, manipulation and analysis and produces fast, reliable results. Our exposure assessment models combine occurrence data (on the level of a given contaminant in foods) with extensive human intake data (from individual food diaries). The FSA needs to estimate the likely level of human exposure to such chemicals, either from individual foods, or from the diet as a whole. lead or cadmium), as well as certain pesticides and food additives.
These include environmental contaminants (e.g. There are many types of chemical whose presence in food can pose some level of risk for consumers. Genstat has been deployed in many important areas of FSA activity, including the following:. We aim to ensure that food produced or sold in the UK is safe to eat, consumers have the information they need to make informed choices about where and what they eat and that regulation and enforcement is risk-based and focused on improving public health. Everything we do reflects our vision of ‘Safer food for the nation’.
