“…The present online survey provides a useful analysis of the current level of implementation of BSM by rural veterinarians, which is in line with the general outcomes of previous biosecurity studies implemented in Europe (Anderson, ; Brennan & Christley, ; Gunn et al., ; Heffernan et al., ; Laanen et al., ; Mee et al., b; Nöremark et al., ; Nöremark & Sternberg‐Lewerin, ; Sarrazin, Cay, Laureyns, & Dewulf, ; Sayers et al., , ; Toma, Stott, Heffernan, Ringrose, & Gunn, ; Villarroel, Dargatz, Lane, McCluskey, & Salman, ). It also highlighted the areas of improvements.…”

“…Veterinarians play a major role as key informants on the BS for cattle holders; indeed, they consider their veterinary practitioner as the main source of information and adopt BSM based on veterinary advices (Gunn, Heffernan, Hall, McLeod, & Hovi, ; Heffernan, Nielsen, Thomson, & Gunn, ; Sayers et al., ). On the other hand, veterinarians also represent an important risk factor in terms of disease spread, as many studies have listed visitors, and more specifically professional visitors such as veterinarians, as a key risk factor in terms of bio‐exclusion (Anderson, ; Brennan & Christley, ; Canadian Food Inspection Agency, ; Maunsell & Donovan, ; Mee, Geraghty, O'Neill, & More, ; NADIS, ; Nöremark, Frössling, & Lewerin, ; Sayers et al., ; van Schaik et al., ; van Winsen et al., ). Meanwhile, an ongoing survey implemented in Belgian cattle farms (unpublished data) confirmed that most cattle holders were not feeling comfortable in asking their veterinarians to wear clean and/or specific work clothes or boots when visiting their premises; they prefer relying on their professionalism in that regard.…”

The implementation of biosecurity measures in the animal health and production context is quite broad and aims at limiting the risk of introduction and spread of diseases. Veterinarians play a major role in biosecurity as key informants on the subject for cattle holders, key players in terms of disease prevention/control and eradication programs, as well as key risk factor in terms of disease dissemination. Many biosecurity studies have highlighted professional visitors such as veterinary practitioners as representing a high-risk factor in terms of disease introduction in animal facilities but, to date, very few studies have focused on the implementation level of biosecurity measures by veterinarians. An online survey was implemented in three European countries (Belgium, France and Spain) to assess the behaviour of rural veterinarians towards biosecurity, as well as their implementation level of the biosecurity measures. A descriptive analysis of data and a scoring system were applied to assess the implementation level of measures. The influence of different factors on the implementation level of biosecurity measures was investigated through a negative binomial regression model. The study identified different strengths, weaknesses, possible constraints and solutions in terms of veterinary perspectives. Veterinarians are considered as key informants by the farmers and could therefore play a more active role in terms of guidance and improvement of biosecurity at farm level. Based on the survey outcomes, two factors seemed to influence significantly the implementation level of measures: the country where he/she practices and the veterinarian's perception level of biosecurity. The biosecurity stages with the lowest application level, therefore representing the biggest threats, were bio-exclusion (increasing the risk of disease introduction) and biocontainment (increasing the risk of inter-herd transmission).

“…The results generated did indeed highlight this trend with results from the multivariable model indicating a greater likelihood of being bulk milk positive to Salmonella in the southern region. A recent review of farm biosecurity has highlighted maintenance of a closed herd (not purchasing animals) as an important component of a farm biosecurity plan (Mee et al, 2012). In the present study, however only 18% of respondents did not introduce newly purchased cattle onto their farms.…”

A survey of management practices in 309 Irish dairy herds was used to identify risk factors for the presence of antibodies to Salmonella, Neospora caninum and Leptospira interrogans serovar hardjo in extensively managed unvaccinated dairy herds. A previous study documented a herd-level seroprevalence in bulk milk of 49%, 19% and 86% for Salmonella, Neospora caninum and leptospira interrogans serovar hardjo, respectively in the unvaccinated proportion of these 309 herds in 2009. Association analyses in the present study were carried out using multiple logistic regression models. Herds where cattle were purchased or introduced had a greater likelihood of being positive to leptospira interrogans serovar hardjo (P < 0.01) and Salmonella (P < 0.01). Larger herds had a greater likelihood of recording a positive bulk milk antibody result to leptospira interrogans serovar hardjo (P < 0.05). Herds that practiced year round calving were more likely to be positive to Neospora caninum (P < 0.05) compared to herds with a spring-calving season, with no difference in risk between herds that practiced split calving compared to herds that practiced spring calving. No association was found between presence of dogs on farms and prevalence of Neospora caninum possibly due to limited access of dogs to infected materials including afterbirths. The information from this study will assist in the design of suitable control programmes for the diseases under investigation in pasture-based livestock systems.

“…These pathogens, which are found in raw milk (D'Amico and Donnelly, 2010;Mee et al, 2012), can persist in the cheese-making environment and contaminate cheese during production (Ahmed et al, 2000;Hill and Warriner, 2011). To our knowledge, no other similar studies have evaluated risk factors related to microbiological quality on cheese farms.…”

The purpose of this paper was to evaluate, by statistical analyses, risk factors on cheese farms that can influence the microbial contamination of their products. Various assessment tools, such as cheese production questionnaires, food handlers' knowledge testing, and hygiene assessment system surveys, were used on 39 cheese farms on the island of Gran Canaria, Spain. The microbiological status of 773 raw milk and cheese samples from the cheese farms was assessed by enumerating total viable counts and 4 pathogens: Escherichia coli, Staphylococcus aureus, Listeria monocytogenes, and Salmonella spp. The results revealed that the highest contamination by Staph. aureus (4.39%, >10 5 cfu/ mL) was found in milk, and the highest contamination by E. coli (5.18%, >10 3 cfu/mL) was found in cheese. Very few samples (0.52%) were contaminated by L. monocytogenes or Salmonella spp. The factors associated with any tested microorganism were "handling," "knowledge," and "type of milk." Subsequently, multidimensional logistic analysis for contamination by E. coli showed an independent association for factors "cleaning and disinfection test" and "type of milk." The probability of total aerobic contamination of milk increased with lower hygiene assessment system survey scores. These results emphasize the need to apply and maintain good hygiene practices, and to study risk factors to prevent contamination and bacterial growth. Further research is required in other areas with different cheese farm types to reinforce the validity of these results.
