低温冰存肉類可殺蟲嗎?

美國政府網站說明0 °F(-17.78 °C)是可以殺蟲,但要在穩定溫度一段時間下才能殺到蟲。家用冰櫃會常開關較難保持在穩定溫度。
 
所以外國生肉餵飼者建議對來源成疑的肉類最好先低溫冰存2星期才餵飼。外國的冰櫃比香港的大,我們冰櫃的溫度更難長期穩定,為安全起見,宜將新鮮肉類放入冰箱冷藏再多數星期殺蟲殺卵。

Trichina and other parasites can be destroyed by sub-zero freezing temperatures. However, very strict government-supervised conditions must be met. Home freezing cannot be relied upon to destroy trichina. Thorough cooking, however, will destroy all parasites.

Adequately freezing or cooking fish will kill the parasite.

I recommend you deep-freeze salmon and all types of anadromous fish (fish that swim upstream to spawn) for at least 7 days if you plan to feed it raw, or cook it before feeding it to your pet.

Trichinosis 毛線蟲
The important thing to remember about Trichinella is this: if you freeze pork for three weeks prior to feeding it, all will be well.
Toxoplasmosis 弓漿蟲
So to avoid toxoplasmosis, freeze meat for 24 hours prior to feeding.
Salmon Parasites
deep-freeze salmon for at least seven days if you’re going to feed it raw, or cook it before feeding it to your pet.
