Check the transparency and effectiveness of Hong Kong's rodent control policy data
Dear Food and Environmental Hygiene Department,
I’ve been doing research on your team’s rodent control measures. Here are the questions for the department to answer under the Code on Access to Information.
Q1 — Machine-readable data and 2024+ results
Request: (a) Can the RIR data for 2013–2023 be provided in machine-readable format (CSV/XLSX)?
(b) Will the 2024 and 2025 RIR data be published in the same detailed format as 2023?
(c) Is there a schedule for transitioning from PDF-only publication to machine-readable open data?
Q2 — Complaint data linkage
Request: (a) Are rodent-related complaints (via 1823 and FEHD hotline 2868 0000) tracked by district and linked to RIR survey locations?
(b) For 2020–2025, what is the annual number of rodent complaints by district?
(c) Does FEHD use complaint data to identify hotspots or adjust survey locations?
Q3 — Species-level data
Request: (a) Does the RIR survey record which rodent species are found at each survey location?
(b) If so, can species-level data be provided by district and year?
(c) Are control strategies tailored based on species dominance?
Q4 — List of measurements
Request: (a) How many times are rodent infestation measurements carried out in the past 12 months?
(b) Based on what kind of information (visual sightings, traps, complaints, environmental indicators)?
(c) After carrying out the measurements, how does FEHD examine the effectiveness of interventions (e.g., comparing before/after infestation rates, complaint trends, or trap success rates)?
Yours faithfully,
Long Chan
