Development of the profit-oriented food enterprises, growing consumers’ expectations and concerns as regards food quality and safety, as well as increasing requirements of food chain actors, forced many companies to improve safety and quality of their products through implementation of the quality and safety assurance and management systems. This chapter attempts to discuss the problem outlined...

The paper tackles the issue of food safety, which is generally defined as the assurance that food will not cause harm to the consumer when it is prepared and/or eaten according to its intended use. Echoing the recognition by the Food and Agriculture Organization (FAO) in 1996 that food safety is an element of food security, the paper discusses the importance of the food trade in the economies o...

A nonautonomous Leslie-Gower type food chain model with time delays is investigated. It is proved the general nonautonomous system is permanent and globally asymptotically stable under some appropriate conditions. Furthermore, if the system is periodic one, some sufficient conditions are established, which guarantee the existence, uniqueness, and global asymptotic stability of a positive period...

Mercury is one of the more toxic elements to living organisms. It is encountered at relatively low concentrations in the environment but with its amplifi cation through the food chain, the fi nal concentration in some foods can be relatively high. In addition, its toxicity is not only linked to its total concentration but is also dependent on the species. Mercury speciation in food analysis is ...

BACKGROUND The use of the generic term "meat and animal derivatives" in declared ingredient lists of pet foods in the European Union is virtually universal. In the wake of the 2013 "horse meat scandal" in the human food chain, we examined the presence and authenticity of animal sources (cow, chicken, pig and horse) of proteins in a range of popular wet pet foods in the United Kingdom. FINDING...

The concept of substantial equivalence, introduced for the risk assessment of genetically modified (GM) food, is a reducing concept because it ignores the context in which these products have been produced and brought to the consumer at the end of the food chain. Food quality cannot be restricted to mere substance and food acts on human beings not only at the level of nutrition but also through...

In this paper, based on the imbalance of the supply-demand relationship of food, we design a spreading model of food safety risk, which is about from food producers to consumers in the food supply chain. We use theoretical analysis and numerical simulation to describe the supply-demand relationship and government supervision behaviors' influence on the risk spread of food safety and the behavio...

Dr Silvia Estrada-Flores is Principal Consultant of Food Chain Intelligence, a consultancy business that provides advice in the practical aspects of the supply chain of perishable foods, from gate to plate; technical intelligence on the state of food logistics and food value chains; and operating procedures and plans to achieve an integrated supply chain. Silvia has worked extensively as a cons...

The abiotic environment has strong influences on the growth, survival, behavior, and ecology of aquatic organisms. Biotic interactions and species life histories interact with abiotic factors to structure the food web. One measure of food-web structure is food-chain length. Several hypotheses predict a linear relationship between one environmental variable (e.g., disturbance or ecosystem size) ...

Food allergy, a significant public health concern in the developed world has a forensic context. Allergy related personal injury, fatality or criminal non-compliance with food law on the part of a food supplier are issues that have come before the UK courts. More recently substitution of peanuts for more expensive almonds has been discovered. Substitution, accidental or deliberate, subverts avo...
