GB/T 38738-2020 in English

This standard systematically regulates the full-process operation requirements of the prevention and control of vector-borne diseases in farmers' markets, highlights the principle of environmental governance priority, and establishes a supporting protection facility system. The density control level assessment method is adopted at the technical level, and scientific prevention and control is achieved through quantitative indicators such as the invasion rate and facility qualification rate.

1. Grain, oil and cooked food area

Triple protection is required: ① Place shelves 30cm above the ground and wall ② Place 1 Poison bait station ③Install electric fly killer lamps (height ≥ 2m)

2. Fresh meat and aquatic product area

Four major parts should be treated: freezer pads, sewer outlets, chopping board gaps, and pipe interfaces. Requirements: ①Use seamless countertops ②Check cockroach glue baits weekly ③The wax block poison bait placement rate is 100%

Phase-based promotion plan

1. Baseline survey period: Complete the background survey of 4 types of vectors according to Appendix A
2. Facility renovation period: Focus on improving rat-proof door panels (height ≥ 60cm) and fly-proof screens (mesh number ≥ 16)
3. Chemical control period: use anticoagulant rodenticides (such as bromadiolone) and microcapsule suspensions (retained spraying)
4. Effect evaluation period: retest density 14 days after control, requiring rodent density reduction rate ≥ 80%
