    We surveyed Finnish local food control officials' opinions about the use and challenges of administrative enforcement measures. Responses to the questionnaire were received from a total of 129 food control officials, covering 72.6% of the 62 local food control units in Finland. In the opinion of 42.7% of the respondents, enforcement measures are not used often enough in their unit to ensure forod safety. Based on our results, large units have better practical tools such as templates for enforcement decisions and guidelines that facilitate the use of enforcement measures than small units, but uncertain practices and a lack of routine appear to impede the use of the measures in many units. Particular challenges highlighted by the officials were related to laboriousness and slowness of the administrative process and reasoning for using enforcement measures. Moreover, impairment of cooperation with the food business operator as a consequence of using enforcement measures was of concern for many officials. The officials assessed the expertise of the head of the unit more positively in the units in which enforcement measures were used than in the units in which enforcement measures were not used, and participation in trainings was the strongest explanatory factor for the use of enforcement measures among the inspectors. Our results indicate that development of operating procedures and provision of specific training on administrative procedure with a practical approach play a key role in strengthening officials' expertise and confidence in using enforcement measures. Moreover, merging the small units with the large ones may promote uniform practices and better capabilities to use enforcement measures in all units. (C) 2017 Elsevier Ltd. All rights reserved.

    Gastrointestinal parasites, Parascaris sp. and strongyles, are common in young horses worldwide and control of these parasites is challenged by increasing anthelmintic resistance. Our aim was to identify risk factors for these infections as well as to assess the efficacy of fenbendazole (dose 7.5 mg/kg) and pyrantel embonate (dose 19 mg/kg) against Parascaris sp. We also evaluated association between owner observed symptoms and patent infections with these parasites. Fecal samples were collected from 367 young horses in Finland and a questionnaire study was conducted. Fecal egg counts were performed by Mini-FLOTAC (R) method. Univariable logistic regression models using patent infection status (Yes/No), separately for Parascaris sp. and strongyle infections as an outcome were run initially to screen potential risk factors collected by the questionnaire. After the initial screening, multiple logistic regression models were constructed and run to account for correlated data structure, risk factors and potential confounders simultaneously. Two significant risk factors for a patent Parascaris sp. infection were found: breeding farm size (p = 0.028) and frequency of horse movements (p = 0.010). Horses originating from large breeding farms were more likely (OR = 2.47, 95% confidence interval (CI) 1.10-5.51) to shed Parascaris sp. eggs upon relocation to training stables compared to horses originating from small breeding farms. Horses living in farms with frequent horse movements to other premises had higher odds (OR = 3.56, 95% CI: 1.35-9.39) of a patent Parascaris sp. infection compared to farms with less frequent horse movements. Risk factors for patent strongyle infection included age (p <0.001) and season (p = 0.017). Horses were less likely (OR = 0.27, 95% CI: 0.10-0.66) to shed strongylid eggs during the spring compared to the winter. Horses excreting over 200 ascarid eggs per gram were included in the anthelmintic efficacy trial. A mean FECR less than 90% was interpreted as presence of anthelmintic resistance. The mean FECR was 98.5% (95% CI: 95.8-100) and 68.0% (95% CI: 52.7-83.3) in the fenbendazole (n = 31) and pyrantel (n = 26) treatment groups, respectively. In conclusion, we identified two new risk factors for patent Parascaris sp. infection; breeding farm size and frequency of horse movements. Reduced efficacy of pyrantel against Parascaris sp. was observed for the second time in Europe. A relatively high Parascaris sp. prevalence in yearlings (34%) and two-year-olds (20%) was observed, which has not been reported earlier. An association between symptoms and a patent Parascaris sp. infection was observed in foals.
