0223~Frontline＝毒？

23-02-2012  星期四

Frontline = 毒? 應否繼續使用?
這個話題係我們這班養狗人士在這幾年間中會傾的……但最後都係無結論

今天在「面書」見到狗友發出這資料令我又想思考這問題
What Are the Dangers of Frontline? http://www.ehow.com/about_5448397_dangers-frontline.html#ixzz1npzedD4F

我已知有些朋友已停用Frontline滴劑, 轉用噴的, 而且轉用天然噴劑.
雖然我已幫pi pi由每月用Frontline滴劑, 轉為隔月用, 而在出草地或行山活動時, 我會幫pi pi噴上天然噴劑, 仲會隔幾小時補噴. 平時PI PI 還戴有防牛蜱帶.
網友見意用Frontline滴劑日後睇埋季節/天氣……春夏秋用, 但冬天停用, 還有情况天氣而定.
而停用Frontline滴劑, 我還是15/16考慮中.

Frontline滴劑所謂防蚤防牛蜱原理係︰ Fleas(跳蚤)and Ticks(牛蜱)咬落動物身上後吸吮血時, 同時吸吮到Frontline 的毒藥後死亡, 而如果跳蚤或牛蜱本身有卵, Frontline Plus滴劑可把體內的卵殺死, 預防再繁殖落去. 但如果牛蜱本身有tick fever (高溫牛蜱熱)都會傳染俾動物的.
Frontline並非預防得到tick fever……相信這點你和我都知.

造成牛蜱熱(Tick Fever)的原生菌就躲在牛蜱的口水中，當牛蜱分泌含抗凝血劑的口水來吸血的時候, 牛蜱菌(Babesia)就會趁機進入狗狗血液中，躲在狗狗的紅血球裡開始繁殖。這時狗狗的白血球就會啟動防衛機制，寧枉勿縱的開始瘋狂攻擊紅血球，以殺死躲在紅血球中間的牛蜱菌。 而牛蜱菌也會破壞紅血球，但真正對紅血球的破壞主要還是來自白血球的不分敵我的瘋狂屠殺!這時所有的測試都會指向自我免疫系統的溶血性貧血， 但其實主要原因是躲在紅血球裡的間諜!

患上牛蜱熱可能出現的病徵:
食慾不振、 精神不好、體重減輕、 倦怠、 偶爾嘔吐、尿尿顏色變深或有褐色或橙色的尿 (溶血後的血紅素露了出來)、發燒、牙肉和舌頭蒼白、發燒、因肺出血而呼吸困難等，但有部份狗狗的病徵並不明顯

而如果狗狗本身健康/抵抗力好, 跳蚤和牛蜱係唔會走上動物身體上的.
我朋友試過……同一個草地, 平時同狗狗去玩/散步無事, 忽然有2-3日行完返屋企見到狗狗身上有跳蚤. 事後傾開才知狗狗那2-3日精神有少少差, 但都有精神食和玩的……所以治標治本預防跳蚤或牛蜱上身方法, 首要係提升身體免疫力！

What Are the Dangers of Frontline?
Frontline is a popular pet medication used to prevent flea infestation in dogs and cats. While fleas are a nuisance to pets and households, there are some concerns about the use and potential hazards of Frontline as a flea preventative. Adverse effects stemming from the active ingredient in Frontline have been identified for people, pets and other wildlife.

Significance
Frontline is a popular flea treatment for dogs and cats. Manufactured by Merial Pharmaceuticals, the active ingredient in Frontline is fipronil, licensed for use in veterinary medicine as a pesticide. Frontline is applied topically and absorbed through the skin of dogs and cats to prevent flea infestations which can cause skin and health issues for pets and households. According to the manufacturer, Frontline is waterproof and is a veterinarian-recommended flea and tick preventative.

Function
Fipronil, the primary active ingredient found in Frontline, is an insecticide from the phenylpyrazole chemical family. It is used not only for flea and tick solutions like Frontline but in other pesticides used for insect management. Fipronil is a common ingredient for solutions managing ants, beetles, cockroaches, termites and other infestations. On its own, fipronil is a white power. As an active ingredient in Frontline, fipronil is part of a liquid solution designed to protect the animal as it stores in sebaceous glands in the skin. Fipronil destroys insects by disrupting the normal function of the nervous system in insects and is considered more toxic to insects than human and animals.

Hazards for Dogs
Despite fipronil and Frontline's determined safety for animals as a flea preventative, there has been controversy over how safe these products are in long term pet health. According to Whole Dog Journal, a monthly dog care and training publication, the active ingredient found in Frontline is a chemical that has demonstrated potential for nervous system and thyroid toxicity after long term exposure. Even at low dosages, it has been determined that fipronil can potentially cause skin problems, reproductive and hormone issues.

Hazards for Humans
Though application instructions provide instructions for people in applying Frontline on their pets, there is still risk and concern in handling Frontline for the owner. Instructions indicate not to allow the solution to come in contact with human skin. In the event that it does, it is advised to wash the hands immediately and avoid touching other parts of the body. Direct, short-term contact with the skin can result in minor irritation. If ingested, Frontline's active ingredient can cause nausea, headaches, stomach pains, sweating and even seizure. While Environmental Protective Agency research is inconclusive on fipronil's cancer causing effects on humans, it is still classified as a possible human carcinogen.

Hazards for Wildlife
According to the Journal of Pesticide Reform, flea prevention medications like Frontline persist on the skin of an animal treated with the solution for as long as 56 days. During that time, the animal will likely have contact with people and its greater environment. As a general pesticide, the active ingredient fipronil is considered toxic to birds, lizards, fish and other animals, even in minute concentrations with research showing clear adverse effects in reproduction.
