Evaluation of street food vendors’ hygienic practices using fast observation questionnaire

The aim of this study was to check the compliance of street food vendors hygienic practices with requirements of the Codex code of practice - general principles on food hygiene and of the Regulation (EC) No. 852/2004. The materials were 110 street food vendors located in Athens, Greece. Specially designed questionnaire allowed fast data collection. The lowest ratings were found in the hygiene of food preparation and serving, that was related to basic infrastructure, especially the protection of light bulbs from glass spreading in case of breaking, and protection of hair from falling into food by wearing sufficient hair covers or caps. Much higher ratings were found in separation of fresh food from ready-to-eat one and in the section of personal hygiene - lack of visible cuts or skin disease symptoms on hands. One of the most interesting findings is that street vendors selling meat or fish meals obtained higher ratings than vegetable or fruit ones. A greater effort should be made to increase hygiene level especially in the case of small mobile food vendors. Because of variation in hygiene level there is a need for more inspections covering greater number of street food vendors. Due to high popularity of street food and its importance for tourism, more effort should be made to improve the degree of compliance with the hygiene requirements. The fast observation questionaire used in this study allowed rapid assessment of implementation of hygiene principles. Further research is needed to explain why, despite food safety authorities licencing and inspection, implementation of hygiene principles by street food vendors is often incomplete and what factors affect the correct operation.     

A review of motivational models for improving hand hygiene among an increasingly diverse food service workforce

Poor hand hygiene is a leading cause for the spread of foodborne illnesses in the foodservice industry. A series of complex motivational interventions must be employed to permanently change the behavior of workers, to increase their compliance and sustain appropriate levels of proper hand hygiene. Unlike the healthcare industry, which uses large, costly multi-modal behavior modification strategies, the foodservice industry must deploy rapid, cost-efficient strategies that take into account a high employee turnover rate and diverse demographics. This paper reviews the current motivational models used in the foodservice industry and examines the habitual nature of complying with good hand hygiene. It also reviews current techniques to increase hand hygiene compliance using clues from three of the five basic senses (sight, hearing, and smell) and two mechanisms (context-bridging and disgust). Lastly, the current model for habit intervention is evaluated, and its possible applications in the foodservice industry with additional reminders are accessed. We believe that this review will provide foodservice managers the background, theoretical basis and practical applications for making long-term changes in their employees on this and similar critical behaviors in foodservice.     

Evaluation of the oral health status in Chinese hemodialysis patients

Chronic kidney disease has become a worldwide public health problem, and it negatively affects oral health. However, the data of the hemodialysis (HD) patients in Chinese population is unknown. This study was aimed to evaluate the dental health status and oral hygiene behavior of the HD patients in China. Patients undergoing HD therapy at two hospitals were asked to finish a questionnaire and receive dental examination (DMF‐T). A total of 306 patients, aged 24–88 (58.09 ± 14.06), took part in this study. Although majority of the patients (77.78%) brushed their teeth at least twice a day, few (less than 5%) had ever used dental floss or mouthwash. More than half of the patients have not visited a dentist since the commencement of HD therapy. The dental examination showed that DMF‐T was 9.63 ± 7.54, and the number of filled teeth (F‐T) was only 0.70 ± 1.48. Moreover, the average caries restoration ratio and replacement index were 17.57% and 32.59%, respectively. HD therapy seems to prevent patients from visiting a dentist, and there is a great need for dental treatment for Chinese HD patients.     

Knowledge on food hygiene of food service staff working in nursing homes and kindergartens in Porto region – Portugal

In this study the food-hygiene knowledge of food handlers working in nursing homes and kindergartens was evaluated. From a global population of 1392 food handlers, a sample was selected of 335 participants from 155 institutions (kindergartens and nursing homes), in the region of Porto, Portugal. Data was collected through a self-administrated, multiple-choice questionnaire that was filled-in individually, in the presence of the researchers. The average score of correctly answered questions was 13.9 (±3.65SD), corresponding to 60.7% of the questions. The level of knowledge shown was heterogeneous, varying according to the topics covered and the socio-demographic characteristics of the participants, although some pattern could be discerned as to areas of strength and weakness. Knowledge relating to temperature control (44.2% of correct answers) and to risk associated to foods (50.2% of correct answers) was significantly lower (p < 0.001) than the overall knowledge (60.7% of correct answers). Education and training (over the previous 12 months) were positively correlated to higher knowledge on food hygiene (p < 0.001). The same could not be verified in relation to hazard analysis and critical control points (HACCP) implementation (p = 0.454). The results underline the importance of assessing training needs and consider such needs when designing training programs.     

Public service mental health practice and psychology: Historically at the cutting edge.

Public service psychologists have led in the systematic use of new approaches to assessment, diagnosis, therapeutic interventions, and organizational management of mental and physical disorders. Outstanding examples include the MMPI and its successor developed at the University of Minnesota; elaboration of its 2-point code types and additional clinical scales at VA Medical Centers; David Wechsler’s work on intelligence and memory measurement at Bellevue Hospital, New York; early adoption of group therapy, early development of family therapy, token economies, and adult mental hygiene clinics; and finally the impetus for the development of accreditation in professional psychology.

Quarter and cow risk factors associated with the occurrence of clinical mastitis in dairy cows in the United Kingdom

Quarter and cow risk factors associated with the development of clinical mastitis (CM) during lactation were investigated during a 12-mo longitudinal study on 8 commercial Holstein-Friesian dairy farms in the southwest of England. The individual risk factors studied on 1,677 cows included assessments of udder and leg hygiene, teat-end callosity, and hyperkeratosis; body condition score; and measurements of monthly milk quality and yield. Several outcome variables for CM were used for statistical analysis, which included use of generalized linear mixed models. Significant covariates associated with an increased risk of CM were increasing parity, decreasing month of lactation, cows with very dirty udders, and quarters with only very severe hyperkeratosis of the teat-end. Thin and moderate smooth teat-end callosity scores were not associated with an increased risk for CM. Cows that recorded a somatic cell count >199,000 cells/mL and a milk protein percentage <3.2 at the first milk recording after calving were significantly more likely to develop CM after the first 30 d of lactation. There was no association between cow body condition score and incidence of CM. Of the cases of CM available for culture, 171 (26.7%) were confirmed as being caused by Escherichia coli and 121 (18.9%) confirmed as being caused by Streptococcus uberis. Quarters with moderate and very severe hyperkeratosis of the teat-end were at significantly increased risk of clinical E. coli mastitis before the next visit. Quarters with very severe hyperkeratosis of the teat-end were significantly more likely to develop clinical Strep. uberis mastitis before the next visit. There were strong trends within the data to suggest an association between very dirty udders (an increased risk of clinical E. coli mastitis) and teat-ends with no callosity ring present (an increased risk of clinical Strep. uberis mastitis). These results highlight the importance of individual quarter- and cow-level risk factors in determining the risk of CM associated with environmental pathogens during lactation.

Unsafe water,sanitation and hygiene in Nigeria’s public spaces: the political economy angle

Water, sanitation and hygiene (WaSH) services in public spaces are examined from the political economy perspective in Nigeria. Through field observations and interviews, the study observed that WaSH practices at public spaces are less than optimal on account of poor or outright absence of necessary WaSH infrastructure and weak or non-existent regulation and enforcement of necessary standards, among other challenges. Socio-economic factors related to the category of users and the proprietary interests of specific spaces largely accounted for WaSH services inequality. It is argued that the failure of the state to guarantee functional WaSH infrastructure and enforce standard practices opens space for differentiated practices and standards consistent with specific interests.
