Rodent infestation rate

Rodent infestation rate (RIR) = (No. of bait consumed by rodent/ total no. of bait collected from the specific area)*100%

The map shows the RIR for the first half of 2008 in Hong Kong. Yau Tsim Mong has the highest RIR of 16.9% (coloured in red) and Eastern district has the lowest, 2.7%.

When the RIR of a district exceeds the 10 per cent, the Food and Environmental Hygiene Department (FEHD) would step up the rodent disinfestations operations. When an RIR reaches 20 per cent or higher, the relevant Government departments will form a joint task force and launch a special rodent control operation to strengthen rodent disinfestations and cleansing services comprehensively, and to promote rodent control in the community.

In addition, the figure of Yau Tsim Mong is different from the data retrieved from FEHD, it is because FEHD uses 19 districts with Mong Kok as one independent district. Whereas Spatioepi uses the 18 administrative districts to display the data, where Mong Kok is part of Yau Tsim Mong.

鼠患參考指數

鼠患參考指數是鼠餌被老鼠咬囓的比率= (被老鼠咬囓的鼠餌數目 ÷ 仍存的鼠餌總數 × 100%)

地圖顯示二零零八上半年香港各區鼠患參考指數。其中以油尖旺區的指數最高，達16.9%（紅色），東區指數最低，2.7%。當任何一個分區的鼠患參考指數高於百分之十，食環署便會加強有關地方的滅鼠工作。如鼠患指數達百分之二十或以上，政府相關部門便會組成聯合專責小組，展開防治鼠患特別行動，包括全面加強滅鼠和潔淨服務，並在社區推廣防治鼠患信息。

此外，數據與食環署數據有出入，由於食環署數據劃分十九區，以旺角區為一獨立區。而Spatioepi根據本港十八區分區劃分形式，將旺角區數據歸納於油尖旺區中。
