One of the main benefits of feeding frozen...
[Outside of the physical danger of feeding ones snake a freaked out, adrenaline rushed critter with teeth and claws whose got nothing to lose by going for a full frontal assault on ones pet snake (not a problem with pinks) ]
One of the main benefits is the actual control of parasite loads in ones feeder prey and can come into play as an important animal husbandry factor.
Feeding Frozen, Thawed mice, it's a good thing...
The act of FREEZING MICE, to kill the various inherent onboard parasites... (such as bacterias, amoeba's..internal and external blood sucking parasitical "bugs")
...is probably the easiest way there is to control many unseen disease transmission vectors.imho.
Freezing fish at minus 4 degrees farenheit = minus 20 degree celcius, for 7 days will kill parasites and prevent illness, according to the U.S. Food and Drug Administration.
According to a large commercial sushi supplier site, they claim that in commercial freezing, a temperature of -40 °F / -40°C will kill any fish hosted parasites in 15 hours and that in a home freezer, at 0° to 10°F, it can take up to five days to kill all the parasites, The raw fish people are probably correct about this.
Although freezing is a very effective method of parasite control, the actual act of "freezing" cannot be relied upon to destroy all parasites such Cryptosporidium (Crypto) oocysts...
a small proportion of oocysts survived 750 hours at -22°C after slow freezing.

"Members of the genus Cryptosporidium are parasites of the intestinal tracts of fishes, reptiles, birds, and mammals.
A number of researchers believe that to date 23 species of cryptosporidium have been named based on host occurrence.It seems however, that members of this genus do not display a high degree of host specificity, so the number of species in this genus remains a matter of some discussion.

Temperature and duration are the key critical elements in the whole "purification" by freezing process.
There is no problem with commercial freezers getting cold enough to be effective... Unfortunately, household refrigerator freezers generally cycle between 5 and 10 degree farenheit, so you've got to crank your home freezer down low to kill parasites, according to the U.S. Food and Drug Administration website.
So the freezing of the prey item for a day or two is apparently not sufficient to kill those teeny,tiny little buggers, I myself would go for a week,minimum, in that home freezer to (hopefully) be an effective vector control technique. imho
