Official controls on traditional and ethnic butchers: evidence gathered to improve food safety.

Regulation 2017/625 allows and encourages the use of rating schemes as a means to increase transparency in the agri-food chain. Since its implementation, a need for greater fairness, consistency, transparency, and objectivity in official controls has been reported by member states. The present study compares the results of inspection activities concerning food hygiene principles in ethnic and traditional butcheries.

A Retrospective Study after 10 Years (2010-2019) of Meat Inspection Activity in a Domestic Swine Abattoir in Tuscany: The Slaughterhouse as an Epidemiological Observatory.

The activities performed by the Official Veterinarian at the slaughterhouse represent a useful source of data for the control of issues affecting human and animal health and welfare. This study analyzed the data deriving from ten years (2010-2019) of meat inspection in a pig slaughterhouse in Tuscany (Italy) to investigate the transport mortality rate and the frequencies and main causes of whole carcass and partial condemnations. In total, 1,246,309 pigs were slaughtered from 8 different regions of Central and Northern Italy.

Antimicrobial Effects of Black Soldier Fly and Yellow Mealworm Fats and Their Impact on Gut Microbiota of Growing Rabbits.

This study aimed to evaluate the in vitro antimicrobial activities of two types of insect fats extracted from black soldier fly larvae (HI, L.) and yellow mealworm larvae (TM, L.) and their effects as dietary replacement of soybean oil (S) on cecal fermentation pattern, and fecal and cecal microbiota in rabbits.

Analysis of the sanitary survey 2015-2017 conducted in the gulf of La Spezia (Italy): Reclassification of the areas of production of live bivalve molluscs.

The sanitary survey is aimed at classifying and monitoring the production areas of live bivalve molluscs (LBM) and it is performed using standards that are provided by the Centre for Environment, Fisheries and Aquaculture Science's Guide to Good Practice. In this study, data from the sanitary survey carried out by the Asl5 Spezzino on the production areas of the gulf of La Spezia during the period 2015-2017 were analysed. The number and type of the analysis performed both on the total sampling and on the individual target species, as well as the number and type of found non-compliance (assessed on both mandatory parameters and on parameters fixed by the local monitoring plan) were considered.

Dairy farm management practices and the risk of contamination of tank milk from Clostridium spp. and Paenibacillus spp. spores in silage, total mixed ration, dairy cow feces, and raw milk.

The occurrence of Paenibacillus and Clostridium spores in silage is of great concern for dairy producers because their spores can contaminate milk and damage processed milk and semi-hard cheeses. Spoiled silage is considered to be the main contamination source of the total mixed ration (TMR), feces of dairy cows, and consequently bulk tank milk via the contamination of cow teats by dirt during milking. The presence of an anaerobic and facultative anaerobic sporeformer population in different matrices (soil, corn silage, other feeds, TMR, feces, and milk) and its transmission pathway has been studied on 49 dairy farms by coupling plate count data with 16S-DNA identification.

Antifungal activity of yeasts and lactic acid bacteria isolated from cocoa bean fermentations.

The aim of this study was to select yeast and LAB strains to be used as a mean of biological control against fungal growth during cocoa fermentation process. Their antifungal activity was assessed against six spoilage fungi isolated from both fermented and dried cocoa beans and belonging to Aspergillus and Penicillium genera. An initial screening was carried out by using the overlay method where the plates were examined for fungi inhibition zone around LAB and yeast streaks.

Human anisakiasis in Italy: a retrospective epidemiological study over two decades.

A retrospective analysis on human anisakiasis in Italy since its first description in 1996 was performed by conducting a literature search. Inclusion criteria based on the presence of a larva and on parasite identification were applied. Epidemiological data and clinical features were analysed.

Retail Stores Policies for Marketing of Lobsters in Sardinia (Italy) as Influenced by Different Practices Related to Animal Welfare and Product Quality.

The aim of the present study was to evaluate the marketing policies of lobsters as influenced by different practices related to product quality in seven supermarkets located in Italy. Retailers were divided in two categories: large scale and medium scale. The two groups were compared to screen for differences and to assess differences in score distribution attributed to different practices related to product quality.

Anisakis spp. larvae in different kinds of ready to eat products made of anchovies (Engraulis encrasicolus) sold in Italian supermarkets.

In this study the occurrence of visible anisakid larvae in semi-preserved anchovy products sold on the Italian market was investigated. Totally, 107 ready to eat products (33 salted-ripened, 49 in oil and 25 marinated) were sampled. Each sample was digested, then the digested material was observed under natural and UV light.

CD49f+ mammary epithelial cells decrease in milk from dairy cows stressed by overstocking during the dry period.

The work reported in this Research Communication describes the modification in epithelial cell populations during the first and the last month of milking in Holstein Friesian cows that have undergone different management during the dry period, and we report the differential expression of CD49f+ and cytokeratin18+ cell subpopulations. Twenty six cows were randomly divided into 2 balanced groups that were housed at stocking density of either 11 m2 (CTR) or 5 m2 from 21 ± 3 d before the expected calving until calving. Cells collected from milk samples taken in early lactation and late lactation were directly analysed for CD45, CD49f, cytokeratin 14, cytokeratin 18 and cell viability.

Meat from cattle slaughtered without stunning sold in the conventional market without appropriate labelling: A case study in Italy.

In the European Union, slaughter without stunning is allowed for religious slaughter to obtain halal and kosher meat. Especially in the case of Jewish slaughtering, cuts which are not deemed as kosher are sold to regular market without any specific labelling. This survey, conducted in Tuscany in 2016, aimed to quantify the carcasses rejected in relation to the type of religious slaughter.

Visceral larvae as a predictive index of the overall level of fish batch infection in European anchovies (Engraulis encrasicolus): A rapid procedure for Food Business Operators to assess marketability.

The European anchovy (Engraulis encrasicolus), one of the most important pelagic fish resources in the Mediterranean Sea, is frequently infected by anisakid larvae. Food Business Operators (FBOs) should use appropriate sampling plans and analytical methods to avoid commercialization of massively infected batches and reduce the risk of transmission of viable zoonotic larvae. In this study, performed at FishLab (Department of Veterinary Sciences of the University of Pisa) during 2016, an official sampling plan was associated with a digestion protocol for the inspection of anchovies.

Dissemination and Persistence of spp. in Small-Scale Dairy Farms.

This study was aimed at collecting data on presence, dissemination and persistence of in small-scale dairy farms. Six farms (located in Piedmont) were visited three times over 2014: 116 waters (wells and different faucets/pipes) and 117 environmental samples (milking equipments and drains) were collected. Enumeration of was performed, 3-5 colonies/samples were selected for identification via 16SrDNA/ polymerase chain reaction (PCR), and typed by enterobacterial-repetitive-intergenic-consensus (ERIC)-PCR.

An association between feather damaging behavior and corticosterone metabolite excretion in captive African grey parrots (Psittacus erithacus).

Background: African grey parrots (Psittacus erithacus) are kept as pets and are frequently hand-reared. It has been observed that hand-reared African grey parrots may develop behavioral disorders such as feather damaging behavior (FDB). It is well known that chronic stress is involved in behavioral disorders in captive parrots.

Detection, identification, and typing of Listeria species from baled silages fed to dairy cows.

Anaerobiosis, critical for successful ensilage, constitutes a challenge in baled silages. The loss of complete anaerobiosis causes aerobic deterioration and silages undergo dry matter and nutrient losses, pathogen growth, and mycotoxin production. Silage may represent an ideal substrate for Listeria monocytogenes, a pathogen of primary concern in several cheeses.

Aflatoxin M1 in Cow's Milk: Method Validation for Milk Sampled in Northern Italy.

Aflatoxins (AFs) are mycotoxins produced by some species of Aspergillus. In dairy cows, ingested AFB1 is metabolized into carcinogenic AFM1 which is eliminated through milk, thus posing a risk for consumer health. Here we describe the set, validation, and application of screening (ELISA) and confirmatory (HPLC) tests carried out on milk samples collected through official control of mycotoxin levels in northern Italy over a three-year period (2012-2014).

The use of loop-mediated isothermal amplification improves Toxoplasma gondii detection in wildlife.

Toxoplasma gondii is among the most widespread parasites worldwide. Wildlife is recognized as an important reservoir and source of infection of T. gondii.

The evolution and epidemiology of Listeria monocytogenes in Europe and the United States.

Listeria monocytogenes is an opportunistic food-borne pathogen responsible for listeriosis, a disease associated with high mortality rates. L. monocytogenes causes invasive syndromes and case-fatality can be as high as 30%, in specific high-risk population groups such as the elderly, immuno-compromised individuals, fetuses and newborns.

Differential expression of living mammary epithelial cell subpopulations in milk during lactation in dairy cows.

Epithelial cells are shed into milk during lactation, and although they generally reflect the cellular characteristics of terminally differentiated luminal cells, previously the detection of more primitive cells was described in human milk where a cell population of epithelial lineage was detected expressing markers typical of progenitor cells. In this investigation, we report the development of flow cytometry analysis to allow multiparametric assessment of mammary epithelial cells observed in milk. Cells collected from milk samples of 10 healthy dairy cows were directly analyzed for 6 different markers: CD45, CD49f, cytokeratin 14, cytokeratin 18, presence of nucleus, and cell viability.

Distribution of Species in a Dairy Plant Affected by Occasional Blue Discoloration.

During 2010 many cases of discoloration in mozzarella, popularly termed as , have been reported to the attention of public opinion. Causes of the alteration were bacteria belonging to the genus . The strong media impact of such cases has created confusion, not only among consumers, but also among experts.

Growth impairment after TBI of leukemia survivors children: a model- based investigation.

Background: Children receiving Total Body Irradiation (TBI) in preparation for Hematopoietic Stem Cell Transplantation (HSCT) are at risk for Growth Hormone Deficiency (GHD), which sometimes severely compromises their Final Height (FH). To better represent the impact of such therapies on growth we apply a mathematical model, which accounts both for the gompertzian-like growth trend and the hormone-related 'spurts', and evaluate how the parameter values estimated on the children undergoing TBI differ from those of the matched normal population.

Methods: 25 patients long-term childhood lymphoblastic and myeloid acute leukaemia survivors followed at Pediatric Onco-Hematology, Stem Cell Transplantation and Cellular Therapy Division, Regina Margherita Children's Hospital (Turin, Italy) were retrospectively analysed for assessing the influence of TBI on their longitudinal growth and for validating a new method to estimate the GH therapy effects.
