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. The sample consists of 50 food business activities randomly selected from traditional and ethnic butcheries subject to official control in Turin from January to June 2019. Our objectives were to evaluate the degree of awareness and training of food business operators (FBOs) and to compare the written records drawn up by the competent authorities (CAs) during official inspections to evaluate their completeness and uniformity. The presence of old equipment is a common finding in both traditional and ethnic butchers. This could lead to ineffective cleaning operations and inappropriate functioning, which in turn could lead to a dangerous loss of control over products' temperatures. Ethnic butchers showed a higher number of non-compliances for documentary examination, the presence/correctness of self-control plans, and management aspects such as by-product disposal and personnel hygiene. Training is the key point for both CAs and FBOs; inspectors must maintain their professionalism but also adhere to harmonized and intellectually supported criteria, and FBOs must prevent improper behavior. Eventually, we propose strategies to increase the efficacy and homogeneity of records, together with suggestions on how to implement training both for consultants and operators.

Official food safety audits in large scale retail trades in the time of COVID: system control experiences supported by an innovative approach.

This work describes a new methodology used in large scale retail trades in official food safety auditing processes developed during COVID19 emergency. The aim is to evaluate Food Business Operators' (FBOs) Food Safety Management System and its dynamic implementation and to understand the FBO's level of cultural maturity about food safety according to EU Regulation 2021/382. The innovation mainly consists of: a) a pre-audit phase when auditors analyse food business operator's (FBO) selfchecked plan and further documents to identify "markers" and useful evidences (that would be collected in on-site inspections) to evaluate the application of plan by FBO's workers; b) an audit phase consisted of both a check of the company procedures and documents performed by the auditors via web conference and of contextually onsite inspections in a sample of company's supermarkets performed by inspectors teams. The audit methodology here described may be useful, even though it is expensive in terms of time and energy used, for both Competent Authority (CA) and FBOs, regardless of the period of the COVID emergency. The so-structured official control allows the auditors to collect both documentary and on-site evidence at the same time, reaching a broader vision of auditees (not limited to single supermarkets) and a compliant with reality FBOs risk classification. The new approach may give advantages to both audit actors, CA as well as FBO, who may collect "markers" and evidence of the self-checked plan useful to improve FBO's food safety system on the basis of the critical aspects detected during auditing process.

Isolation of Arcobacter species and other neglected opportunistic agents from aborted bovine and caprine fetuses.

BACKGROUND: Infectious abortion in ruminants is a problem in animal husbandry worldwide. It is important to obtain a diagnosis, to make sure that proper control measures can be instituted, but most abortion cases remain without an etiologic diagnosis. This report describes the presence of Arcobacter species and several neglected opportunistic abortifacient agents in ruminant abortion cases showing or not co-infections among at least one of the major recognized protozoal, fungal, bacterial and viral abortifacient agents. RESULTS: A total of 67 fetuses (55 cattle and 12 goats) and just one placenta (cattle) were considered. Among the most common abortive agents, Neospora caninum (19,4%), followed by Chlamydophila abortus (4,5%), Listeria monocytogenes 1/2a (2,98%), Bovine Viral Diarrhea Virus type 1b (2,98%), Bovine herpesvirus 4 (2,98%), and Aspergillus spp. (2,98%) were detected. The isolated neglected opportunistic bacteria include Escherichia coli, Acinetobacter lwoffii, Staphylococcus spp., Streptococcus spp., Streptococcus uberis, Streptococcus suis, Trueperella pyogenes, Mannheimia haemolytica, Bacillus cereus and Nocardia spp. Other bacterial species, not associated with abortion by literature, but described as causes of diseases occurring sporadically both in humans and animals, were also detected. Three Arcobacter strains, namely two A. skirrowii and one A. cryaerophilus, were isolated from 3 bovine aborted fetuses, and A. butzleri was isolated from the placenta. CONCLUSIONS: A not negligible isolation of Arcobacter species and other neglected abortifacient agents has to be mentioned, with prevalences that seem to be emerging and replacing or co-placing the major infectious players in bovine and caprine reproductive failure due to abortion disease, even if further studies investigating the aetiological power and transmission routes are needed in order to define the role of these microrganisms in ruminant abortion.

Arcobacter spp. in raw milk from vending machines in Piedmont and occurrence of virulence genes in isolates.

Arcobacter spp. has been recognized as an emerging foodborne pathogen and a hazard to human health. In the dairy chain, it has been isolated from different sources, nevertheless data on Arcobacter occurrence in raw milk provided by vending machines are few. This study aimed to identify potentially pathogenic Arcobacter spp. in raw milk intended for human consumption sold through vending machines located in Piedmont. In an 8-month period, 37 raw milk samples were collected from 24 dairy farms: 12 (32,4%) were collected directly in farm from bulk tank milk and 25 (67,6%) from vending machines. Eight (21,6%) out of the 37 milk samples and 7 (29,2%) out of the 24 dairy farms were positive for Arcobacter spp. by culture examination. Four (16%) out of the 25 samples from vending machines and 4 (33,3%) out of the 12 samples from bulk tank milk were positive. All 8 isolates were identified as A. butzleri both by MALDI-TOF MS and multiplex end-point PCR. According to the detection of virulence genes, a total of four Patho-types were highlighted: 5 isolates in P-type 1 and only one isolate for each of the P-types 2-3-4. A. butzleri isolates carrying encoding virulence factors genes were isolated from raw milk intended for human consumption: these findings strengthen the compulsory consumption after boiling as required by current legislation and suggest the need of enlarging the analytical investigations to other microorganisms not yet included in the food safety criteria.

Food Safety and Sustainable Nutrition Workshops: Educational Experiences for Primary School Children in Turin, Italy.

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.

Consumers' Perception and Knowledge of Food Safety: Results of Questionnaires Accessible on IZSalimenTO Website.

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.

Occurrence of Thermotolerant Campylobacter in Raw Poultry Meat, Environmental and Pigeon Stools Collected in Open-Air Markets.

Campylobacteriosis was the most commonly reported zoonosis for confirmed human cases in European Union during 2011. Poultry meat was very often implicated in Campylobacter infections in humans. In Italy commerce of raw poultry meat is common in open-air markets: these areas can be considered at high risk of bacterial contamination due to the high presence birds like pigeons. The aim of this study was to collect data about the contamination by thermotolerant Campylobacter of raw poultry meat commercialised in open-air markets, of work-surfaces in contact with poultry meat and of pigeon stools sampled in the market areas in Turin, Northern Italy. Between September 2011 and December 2012, 86 raw poultry meat samples, 86 environmental swabs and 108 animal samples were collected in 38 open-air markets. Analysis were carried out according to ISO10272-1:2006 standard. C.coli was detected in 2.3% (2/86) of raw poultry meat samples, whereas no swab (0/86) resulted positive. Of pigeon stool 28% (30/107) was positive for C.jejuni (83.3% C.jejuni subsp. jejuni and 16.7% C.jejuni subsp. doylei). C.jejuni subsp. jejuni was isolated from 1 dead pigeon. Our results showed lower rates of contamination than those reported at retail in Europe. Although samples were collected in areas at high risk of contamination, raw poultry meat and work surfaces reported a low level of presence of thermotolerant Campylobacter. The high percentage of C.jejuni isolated from pigeon stools showed the importance of a continuous application of preventive measures by the food business operators and the surveillance activity by the Competent Authority.
