nope, that's the recommendation for long term freezer storage. and most chest type freezers can get there. incidently -40F = -40C. yep, it's cold. made my hands hurt just getting the upper over to the bench vise. i should have thought about gloves. refrigerators/freezers will normally not be able to get the freezer part to -40F. usually 0F is about as cold as they go. but a true chest freezer can get very cold. meant for long term food storage. commercial meat locker storage freezers are set to -40 typically, or at least the ones i was familiar with growing up. try going into the freezer on a hot summer day to get some meat out for someone. you go from 95F to -40F. quite a shock. the reason they sent us kids in and didn't let the grandmas and grandpas go fetch their meat. and by the way, Jan nights in Nebr. where i grew up sometimes hit -40. North Dakota hits that temp in the winter regularly over night in Jan. makes one say darn, it's cold out tonight. probably why the population of Nodak is so huge.
