European control and prevention policies are focused to guarantee a high level of protection of consumers’ health. Food-borne diseases as obesity, diabetes, food allergy, and food-borne outbreaks are increasing. To prevent food-borne diseases, it is fundamental to involve consumers, in particular children, in educational experiences aimed to learn the proper behaviours to be applied. In this context, we designed and performed 5 educational workshops about food safety, hidden allergens in food and nutrition aimed to involve children attending primary and summer school. These experiences let us collect observations about children knowledge and behaviours. From May to October 2015, a total of 1708 children aged 6 to 11 years joined our workshops. Children were involved in listening activities, laboratory experiments, handling games and sensory experiences. All participants were familiar with food allergy and were interested to know how to behave with allergic people. Children showed great curiosity in discovering that many foods normally contain live bacteria. Less than 25% of children reported to skip breakfast, to have it watching TV or to spend few minutes for it. Many of them (>75%) thought that fruits and vegetables are all year-round available and are not related to a specific period. Very few participants (<25%) knew that freezing is the treatment to be applied to make fresh fish safe from parasites. Children involved in food safety and nutrition educational experiences have the opportunity to increase their awareness about the correct behaviours to prevent food-borne diseases and to improve their own critical thinking about food consumption. © A.

In October 2012, two persons fell ill with symptoms consistent with staphylococcal food poisoning after eating home-canned tuna fish and tomatoes. Laboratory investigation detected the enterotoxins in the home-canned tuna and molecular analysis of the isolated Staphylococcus aureus confirmed it carried toxin genes. Qualitative enzyme-linked immunosorbent assay and enzime linked fluorescent assay methods and quantitative assay identified the enterotoxins in the food leftovers, specifically staphylococcal enterotoxins type A (SEA) and D (SED), respectively 0.49 and 2.04 ng/g. The laboratory results are discussed considering the relation to the fish in oil, survival and heat resistance of S. aureus, and presumptive microbial contamination due to improper handling during home-canning procedures. This is the first reported cluster of foodborne illnesses due to staphylococcal enterotoxins in tuna in Italy. In this study, we reported cases described and analysed for their spa-type. Showing a high heterogeneity of isolates, spa-type t13252 is correlated in a node of the minimum spanning tree and it has never been reported as responsible for foodborne outbreak. This case underlines the importance of risk communication and dissemination of home-canning guidelines to reduce the incidence of foodborne outbreaks caused by homemade conserves. © G.

The present survey was undertaken to investigate consumers’ knowledge of the main foodborne agents and dietary regimen during pregnancy. Data were collected using monthly questionnaires available on IZSalimenTO website between March 2013 and January 2014. Hepatitis A virus questionnaire: 20 respondents (77%) recognized berries as foodstuff linked to the outbreak of hepatitis A. The majority correctly indicated as precautionary advice to boil berries before consumption. Botulism questionnaire: 29 respondents (62%) indicated pesto as food involved in botulism alert in July 2013. The risk of infant botulism in infant less than 1 year old due to honey consumption is known by 24 respondents (51%). Main foodborne disease questionnaire: the risk of infection by Salmonella after the consumption of foods made with raw eggs is known by the majority (94%; N=17) as well as the treatments to be applied in order to make fresh fish safe from parasites (76%). Pregnancy questionnaire: 20 respondents (74%) believed that washing vegetables and fruits with sodium bicarbonate or chlorate solution is able to inactivate Toxoplasma; only 4 (15%) reported both raw meat and vegetables washed with sodium bicarbonate as food at risk. Results indicate that all consumers should be trained on behaviour and dietary regimen to be adopted in pregnancy and in infant <1 year old. The website may be considered as a useful tool to assess consumers’ knowledge: both the news section and the contents published may be a source of information and education for consumers on food safety. © A.

In the latest year, and also in 2013, Salmonella was the most frequently detected causative agent in foodborne outbreaks (FBOs) reported in Europe. As indicated in EFSA report (2015) the serotypes mostly associated to FBOs are S. Typhimurium and Enteritidis; while Salmonella Typhimurium is generally associated with the consumption of contaminated pork and beef, FBOs due to Salmonella Enteritidis are linked to eggs and poultry meat. In this study it is described the investigation of a domestic FBO involving four adults and linked to homemade lasagne. Investigations were performed to determine the relatedness of Salmonella strains, identify the sources of infection, and trace the routes of Salmonella contamination in this FBO. Salmonella strains were isolated in 3 out of 4 patient stool samples and from lasagne and all of them were serotyped as S. Enteritidis. Pulsed-field gel electrophoresis (PFGE) analysis revealed the genotypical similarity of the all the strains. Although serotyping and PFGE analysis identified the common food source of infection in this FBO, it was not possible to determine how or at what point during food preparation the lasagne became contaminated with Salmonella. © 2015, Page Press Publications.

Sardinia (Italy, north-western Mediterranean) is a commercially important producer of edible bivalve molluscs. Since the early 2000s, it was subjected to recurring cases of mussel farm closures due to toxic algal poison. Here, we present the studies on toxin concentrations and the associated potentially toxic phytoplankton distribution and abundances carried out by a regular monitoring programme in Sardinian shellfish areas, from January to May 2015. Diarrheic shellfish poisoning (DSP) toxins were detected in several bivalve molluscs samples, while paralytic shellfish poisoning (PSP) and paralytic shellfish poisoning toxins were present just once, without exceeding the legal limits. Potentially toxic algal species have been constantly present.
