An interventional study of Improve hygiene practice of pork sellers in Food Borne Diseases and Food Safety, sponsored by The International Livestock Research Institute (ILRI). Completed at 1 site in Cambodia. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2021-09-02.

Safe Food Fair Food for Cambodia (SFFF) is a Feed the Future Innovation Lab project funded by USAID. This 3-year project aims to improve food safety of animal source food (ASF) in Cambodia. SFFF was awarded to the International Livestock Research Institute (ILRI), National Animal Health and Production Research Institute (NAHPRI) and Livestock Development for Community Livelihood Organization (LDC) and in collaboration with Cambodian Ministry of Health CDC and NIPH. Based on the findings and consultations with food safety stakeholders in Cambodia, we have developed a set of interventions to improve hygienic practice and pork safety at the traditional markets in Cambodia. Those interventions will be introduced and tested at retail in six selected provinces using Randomized Controlled Trials (RCT). To ensure compliance of targeted actors (e.g. retailers), participatory methods (e.g. FGD) were used to validate intervention packages. There are two steps of intervention which contain of part 1) Retailer formative research for SFFF Cambodia and 2) Interventions for Good Hygiene Practices for Safer Pork at Traditional Markets.
Part 1. Retailer formative research for SFFF Cambodia: We will implement an intervention package to this trial group and collect biological sampling to determine the hygienic status before and after the intervention. The intervention packages will be developed for SFFF Cambodia in consultation with partners and based on findings of SFFF Cambodia project.
Part 2. Intervention for Good Hygiene Practices for Safer Pork at Traditional Markets: A randomized controlled trial (RCT) intervention will be conducted in 12 markets in 6 provinces. Those provinces were selected based on the prevalence of Salmonella in a market survey study, namely Kampot, Kampong Cham, Kampong Speu, Takeo, Siem Reap, and Phnom Penh. Another 12 markets, in the same provinces, will be used as a control group. In total 24 traditional wet markets will be included in the sampling, by selecting the 4 largest traditional markets in the six provinces with at least 15 pork shops. At each market, 15 pork shops were selected for sampling. The intervention package includes 5 keys actions (Handbook) and provision of equipment incentive (e.g. inox tray, easy-clean surface material), and training on good hygiene practices.
Selection of provinces, markets and retailers
Six provinces were selected including Phnom Penh, Siem Reap, Takeo, Kampong Cham, Kampot, Kampong Speu with the following selection criteria: i) The number of markets in provinces, ii) Salmonella prevalence (above 50%), iii) Population density and risk, urban - rural, iv) Distance from laboratory, v) Compliance of market board and traders, local animal health workers. Phnom Penh had a reported Salmonella prevalence of less than 50% in the recent market study but was included as an urban center with expected high output of pork sells. In each province, four markets which have at least 15 pork shops will be selected. Among those markets, two markets will be assigned for control and trial groups.
Group of retailers will be chosen from selected markets for the intervention based on their "similarity" (e.g., environment, shop facilities, sells volume) and their compliance to participate. Intervention package includes providing incentive equipment and training on good hygiene practice. Equipment provision comprise: (i) equip the shops with inox trays and advise them to separate raw pork/processed pork and intestines; (ii) In case the surface of the shop is not made from granite or inox, we will provide them with feasible surface cover material; (iii) Apron to retailers with the project logo/brand; (iv)Shop's banner with our logo; (v) Hand washing soap (antibacterial) and dish detergent; (vi) Disinfectant spray (Anolyte).
Guide retailers to rearrange their shops to suit their own facility and space. Introduce plastic cutting boards for light cut, check currently used wooden cutting boards at shop to advice to use properly. Introduce frequent washing and disinfection of sale place and shop equipment. Washing with dish detergent and disinfection using spray disinfectant (Electrochemically activated water, pH=7). This shall include:
For control group: No intervention or training activities for this group but collection of biological samples and observation checklist to determine hygienic status at their shops over three consecutive days.
Intervention description
Procedure to introduce the intervention:
Procedure for sampling and analysis:
The International Livestock Research Institute (ILRI) is the lead sponsor of 3 studies on the registry; none are open to participants now.
Counted across the registry records on this site, refreshed daily.
Exclusion Criteria:
No intervention in this group
Hygiene package, training, branding, and certification
Behavioral: Improve hygiene practice of pork sellers
includes 5 keys actions (Handbook) and provision of equipment incentive and training on good hygiene practices, branding, and certification
Proportion of samples fulfill Cambodian microbiological standards for pork
Total bacterial count in pork samples will be measured from both trial and control groups to assess level of compliance with national standards
Time frame: 16 weeks
Change in knowledge of pork retailers
There are 8 questions on the knowledge part. Each correct answer is given 1 score. The minimum and maximum scores of each participant are 0 and 8, respectively. The means of knowledge score will be compared to see the difference between the 2 groups.
Time frame: 16 weeks
Change in practice of pork retailers
The practice will be observed using a checklist during the selling time of the sampling day. There are 20 items on the checklist. Each appropriate practice is given 1 score per item. Practice score will be ranged from 0 to 20. The difference between the 2 groups will be compared using means of practice score.
Time frame: 16 weeks
Plan to share: No — RCT data can be shared for other researchers but not the IPD.
