Rischi e opportunità connessi con la commercializzazione del latte crudo
In the European Community only a few EU
member states have authorized the sale of
raw milk for human consumption, including
Italy where the phenomenon is strongly growing.
Raw milk is richer in enzymes and vitamins
than pasteurized milk, but some potential hazards
are associated with the benefits because
the product keeps the entire microbial flora
that results from the health status of the animal
intact. Most foodborne diseases caused by
the consumption of dairy products are due to
S. aureus, Salmonella spp., enterotoxigenic E.
coli, Listeria monocytogenes and Campylobacter
spp.
Correct information for the costumer is very
important because raw milk, if properly managed,
monitored and evaluated, can be an opportunity
for increasing the farmer’s income
and an opportunity to consume genuine products
without unjustified constraint
MYCOBACTERIUM AVIUM SUSP. PARATUBERCULOSIS NELLA FILIERA LATTIERO CASEARIA
Mycobacterium avium subsp. paratuberculosis (MAP) is the etiologic agent of paratuberculosis. The disease affects cows and other ruminants and causes high economic losses, mainly for dairy production. MAP may also have a role in the development of Crohn’s disease in humans. Infected animals shed viable MAP with milk and faeces and humans may assume MAP via the consumption of contaminated milk and dairy products. Current methods of milk pasteurization are not sufficient to kill all MAP cells present in milk and MAP has been found in raw or pasteurized milk and isolated from cheese. The aim of this paper is to review the current knowledge about MAP in dairy production. We analyzed studies on milk contamination, effect of pasteurization and methods for identification of MAP that can be applied to dairy products

Valutazione dell'attività battericida dell'EOW su matrici alimentari carnee
Electrolyzed oxidizing water (EOW) has potential application as a residue free sanitizing agent for food of animal origin. Meat and poultry were contaminated with microorganism, pathogens or not, and different types of electrolyzed oxidizing water treatement were investigated to evaluate the activity of each of these method. In detail, this study is aiming at evaluating the effectiveness of EOW in reducing microbial count, including total bacterial count, Salmonella Typhimurium, Staphylococcus aureus, Listeria monocytogenes and Escherichia coli on meat and poultry. EOW has a very strong disinfectant activity which, along with its easy and safe use, makes a good alternative to many other more widely used disinfectants

Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
