Full text linkThe research project, “ Chemical risk in food: comparing web- and paper-based communication tools ” , funded by the Italian Ministry of Health, intended to make a comparative assessment of the most effective tools to use in communication campaigns on chemical risks associated with food. The aim of the project was to raise awareness among adolescents about the problem of food safety and, as a result, to reduce the risk of exposure to chemical contaminants contained in food
The objective of the project was to build a message and to disseminate it to a sample of young people aged between 16 and 18 in North East Italy, by means of two tools: one web- and the other paper-based. The choice of storytelling, as a method to develop the message on both the web- and the paper- based tools, is one of the more innovative aspects of the project pilot. Storytelling was identified as a technique able to facilitate understanding of scientific notions and to foster learning by emotionally involving the target. The use of this technique can be considered absolutely original in the communication of risk for consumer safety.
Evaluation showed that the use of the storytelling technique had a positive impact on the target involved. From the data collected through the evaluation questionnaires, it was found that most of the young people (83%) considered the technique to be an effective means of communication able to attract the curiosity of their peers. Besides being an important innovation in the field of food risk communications, the direct involvement of the students in designing the communication tools in the early stages of the project and their participation in building the Digital Storytelling product proved to be a means of arousing the curiosity not only of the spectators but also of the students involved in the participatory process. Implementation of the storytelling technique actually required the young people to reflect on their own experience and daily life and to build a narrative related to the subject in question. In particular, the results of the analyses showed that, of the various elements used to build the tool, the students who saw the Digital Storytelling product reported appreciating that the actors were people of their own age, indicating this as an effective way of conveying the communication message to the identified targe

No full textGrowth performance, behaviour, cleanliness, carcass traits and meat quality of 48 Simmental young bulls housed on slatted floor or on straw bedding with the same space allowance were compared in the study, which lasted 250 days. The animals (initial body weight = 321.2 +/- 34.1 kg) were assigned to 8 balanced groups, according to their initial body weight. All the groups were reared in separate pens with a space allowance of 3 m(2)/head. Four pens had a concrete floor covered with a straw bedding while the other pens had a fully slatted floor made of concrete slats. All the animals received the same diet provided ad libitum. Type of floor did not affect the bulls' daily gain, feed intake and feed efficiency. Health status of the animals was satisfactory throughout the trial and several blood indicators of chronic stress were not modified by the treatment. Behavioural observations carried out at d 10, 80, 180 and 240 showed differences only on some behaviours due to the type of floor. In particular, the straw bedding increased eating behaviour and it encouraged the simultaneous presence of more bulls at the manger. Regardless of the type of floor, the progress of the trial showed a linear increase of animals' inactivity (P < 0.05) while linear decrease of bulls' lying (P < 0.01), eating (P < 0.001) and ruminating (P < 0.01) was observed. These results can be referred to the growth of the animal body frame, which made the space allowance progressively limiting. In the straw bedded pens, clean straw was added weekly and fully renewed every 3 weeks, but this bedding management did not allow a satisfactory cleanliness of the animals in comparison with the slatted floor. However, the worse cleanliness of the bulls on the straw did not promote their grooming activity. Young bulls were slaughtered at a final weight of 614.6 +/- 14.7 kg and their carcass traits and meat quality were not affected by the treatment. The straw bedded system cannot always be considered the cleanest solution for the housing of beef cattle and its frequent renewal must be carried out, particularly when animals are kept with a minimum space allowance. The minimal differences observed for all the parameters measured in the study between the two types of floors must be related to the adoption of the same space allowance/animal and this factor has shown to be the most critical housing parameter affecting beef cattle welfare during the fattening period
