Many countries, in order to authorise the use of food irradiation, claim the availability of methods to detect the occurred treatment in addition to the respect of safe use of this technology. Among physical methods, the electron spin resonance (ESR) measuring the number of free radicals that are formed during irradiation can be applied only to those foods with cellulose, a crystalline or bone structure, in which free radicals have a shelf life greater than irradiated product. The aim of this study was to highlight an irradiation treatment in European and extra-European foods marketed in Southern Italy by the means of ESR technique. Furthermore, in order to optimise the preparation procedures the efficacy of the above mentioned method in fish scales experimentally irradiated has been evaluated. From February to September 2012, a total number of 83 samples of food products of animal and plant origin were taken at the border inspection post and at retail market and finally analysed. At the same time, the scales of grouper and barracuda have been experimentally irradiated at 0.5 kGy and were subsequently analysed using ESR. Results showed 5 frog legs out of 83 samples positive for treatment and confirm the applicability of ESR also for fish scales. © R. Marrone et al., 2014.

Ovine ricotta cheese is a traditional Sicilian dairy product characterised by high humidity and a short shelf life (2-4 days when refrigerated). The increasing demand for fresh food has prompted manufacturers to develop special packaging techniques, such as modified atmosphere packaging (MAP), that can extend the shelf life and maintain the organoleptic characteristics of ovine ricotta cheese. The aim of the present study was to evaluate the shelf life of fresh MAP-packed ovine ricotta cheese by monitoring the microbiological, chemical, physical and organoleptic characteristics of the product. Samples of a single batch were packed in MAP or vacuum packed and stored at 4C for 24 and 7 days, respectively. Water activity, pH, physicochemical parameters and microbiological characteristics were examined. A sensory panel rated the products main organoleptic characteristics (colour, odour, flavour and texture). Results showed that MAP controlled the development of any unwanted microflora, but did not affect the development of intrinsic lactic floras or chemical parameters. Sensory analysis revealed that overall the MAP-packed ricotta remained acceptable for up to 15 days of storage. The vacuum-packed ricotta cheese, however, showed a progressive deterioration in organoleptic characteristics from day 5 onward and therefore had a shorter shelf life. In conclusion, the ability of MAP to extend the shelf life of a traditional regional product (such as fresh ovine ricotta cheese) guarantees consumers a quality product and provides opportunities for manufacturers to expand their markets beyond national boundaries.

The increasing awareness of animal welfare issues among consumers and the general public in the European Union has brought about the adoption of laws for the protection of production animals throughout the various steps of the food chain, from breeding to slaughter. Considering that horses may be kept for a variety of reasons, including as companion animals and as farm animals, protective legislation in Europe applies to this species only partially. In consistency with the areas of competence of the European Union, it is the purpose of the activity (be it economic/commercial or neither) and not the final purpose of the equine (whether they are intended for human consumption or not) along the entire food chain that determines the application of the above legislation. Even horses which are not kept for food production are covered by EU laws when they are bred or transported in connection with a commercial activity, while equines kept for purposes outside this context are protected only by national laws. © Istituto G.

In the last few years the offer of ready to eat food and snacks on the market has been increasing, therefore new challenges regarding preservation have arisen. Predictive microbiology proved to be a useful tool and a guarantee both for the producer assessing the shelf-life, and the control authority. The aim of this study was to assess the shelf-life of a sandwich packaged in protective atmosphere and stored at +4°C, under conditions which change over time but should not allow the growth of Listeria monocytogenes. The most important factors which guarantee the shelf-life are the quality of the raw materials, the hygienic conditions during the production process, the choice of the appropriate packaging materials (i.e. their gas permeability) and the cold chain.

Phoridae, which belong to the Diptera order, were identified as the cause of serious infestations of Apis mellifera colonies in the American continent such as Phoridae from the genus “Melaloncha” in Central America and Apocephalus borealis in the USA. Some authors identified a novel phorid, Megaselia scalaris, as a possible parasitoid of honey bee in Brazil. Recently, in Europe, Diptera from the genus Megaselia was found able to parasitize adults of A. mellifera. So far, in the old continent, such infestation was reported only in bees dead or affected by other diseases, but never in healthy bees. From July through August 2014, the prevalence of myiases affecting A. mellifera was verified in Abruzzo and Molise regions. Most of the selected apiaries showed a great infestation of bees due to M. scalaris, even if they were apparently healthy, during trapping back from their foraging trip. Here, we report the results of our work to stress the impact that this parasitoid might have on health condition of beehive. © 2016 The Author(s).
