Quantitative risk assessment of human salmonellosis from the consumption of typical pork products in the Veneto region of Italy
ARSIS is a pilot scheme commissioned by the Veneto Region aimed at evaluating the risk of salmonellosis for Veneto region mhabitants due to the consumption of \u27insaccati\u27, typical pork sausages. The quantitative nsk assessment (QRA) approach was used to assess the risk of human salmonellosis and to est1mate the number of cases in a year among Veneto inhabitants, divided into sex and age classes
Identification of control strategies to manage microbiological risks in typical pork products
Starting from 2009 a pilot project has been implemented by a local veterinary service of the Veneto region of Italy (AZ-ULSS 8) in collaboration with IZSVe (Istituto Zooprofilattico Sperimentale delle Venezie) with the aim of identifying control measures based on own-checks and official controls in order to manage microbiological risks related to traditional pork fermented sausages (Italian salami end soppresse) consumption. According to the data obtained a control strategy based on microbiological tests performed by the Competent Authority (CA) and the monitoring of the weight decrease in sausages by the food business operator (FBO) has been implemented for 2010-2011 production season
Evaluation of public and animal health risks in case of a delayed post-mortem inspection in ungulates
The potential effects of a 24 or 72-h delay in post-mortem inspection (PMI) of ungulates on public health and monitoring of animal health and welfare was evaluated. The assessment used a survey of meat inspectors, expert opinion, literature search and a stochastic model for Salmonella detection sensitivity. Disease detection sensitivity at a delayed PMI is expected to reduce detection sensitivity to a variable extent, depending on the hazard and on the signs/lesions and organs involved. No reduction is expected for Trichinella detection in meat from susceptible animal species and any decrease in detection of transmissible spongiform encephalopathies (TSEs) will not exceed the current tolerance for fallen stock. A 24-h delay in PMI could result in a small reduction in sensitivity of detection for tuberculosis, echinococcosis and cysticercosis. A greater reduction is expected for the detection of pyaemia and Rift valley fever. For the detection of Salmonella, the median model estimates are a reduction of sensitivity of 66.5% (90% probability interval (PI) 0.08–99.75%) after 24-h delay and 94% (90% PI 0.83–100%) after 72-h delay of PMI. Laboratory testing for tuberculosis following a sampling delay of 24–72 h could result in no, or a moderate, decrease in detection depending on the method of confirmation used (PCR, culture, histopathology). For chemical contaminants, a delay in meat inspection of 24 or 72 h is expected to have no impact on the effectiveness of detection of persistent organic pollutants and metals. However, for certain pharmacologically active substances, there will be a reduced effectiveness to detect some of these substances due to potential degradation in the available matrices (tissues and organs) and the non-availability of specific preferred matrices of choice
Quantitative risk assessment of human salmonellosis from the consumption of typical pork products in the Veneto region of Italy
ARSIS is a pilot scheme commissioned by the Veneto Region aimed at evaluating the risk of salmonellosis for Veneto region mhabitants due to the consumption of 'insaccati', typical pork sausages. The quantitative nsk assessment (QRA) approach was used to assess the risk of human salmonellosis and to est1mate the number of cases in a year among Veneto inhabitants, divided into sex and age classes.</p

Attribution of human Salmonella infections to animal and food sources in Italy (2002-2010): adaptations of the Dutch and modified Hald source attribution models
The Dutch and modified Hald souce attributrion models were adapted to italian Salmonella data to attribute human infections caused by the top 30 serotypes between 2002 and 2010 to four putative sources (Gallus gallus, turkeys, pigs, ruminants), at the points of animal reservoir (farm), exposure (food), and both combined. Attribution estimates were thus compared between different models, time periods and sampling points. all models identified pigs as the main source of human salmonellosis in Italy, accounting for 43-60% of infections, followed by G. gallus (18-34%). Attributrions to turkeys and ruminants were minor. An increasing temporal trend in attributions to pigs and a decreasing one to G. gallus was also observed. Althougn the outcomes of the two models applied at farm and food levels essentially agree, they can be refined once more information becomes available, providing valuable insights about potential targets along the production chain
Further developments in the CUORICINO experiment
We report the present results of the CUORICINO experiment, a cryogenic experiment on neutrinoless Double Beta Decay (DBD) of n130Te consisting of an array of 62 TeOn2 crystals with a total active mass of 40.7 kg. The array is framed inside a dilution refrigerator, heavily shielded against environmental radioactivity and high-energy neutrons, and it is operated at a temperature of 8mK in the Gran Sasso Underground Laboratory. After several improvements the live time of the experiment is near 75%
