the meat they serve at McDonalds does not decompose. so that Happy Meal is really a kind of preemptive embalming kit, right?
nonsense... 
Like I said, nonsense.
I have various meats, some of which I've had for years. It is the result of a little craft I do called meat curing and dehydration. I've done this with sun drying and with the use of controlled dehydrating equipment. Not just meats. I have several pounds of blueberrys that are a decade old.
Without enough moisture, organic material cannot sustain the various micro-organisms. No moisture... decay stops. One of the three primary factors that affect decay is water. Water is needed as a means of transport for the enzymes produced by the bacteria that in turn convert material into something the cells can absorb. Purdy basic Biology.
Chloroform as one of the ingredients? Come on. Its variants are so heterogeneous, I could take a month explaining the basics. However, considering that several of those variants are forms of nerve gas, I won't be doing any such. In it's most abundant form, it is completely natural in our planets atmosphere. As well as the other listed Organochlorines. The primary generation of these chlorines is our oceans. You would be amazed at the action of Sea Spray Aerosols production of much of our atmospheric chlorine. Purdy basic Biochemistry.
Granted, I wouldn't want to be rehydrating one of those burgers any more than I would King Tuts mummy just to have with my refreshing beverage and fries.
BTW most fast food products stored in frozen form are freeze dried. When something is freeze dried, almost 100 percent of the water is removed during primary drying. Now I'm purdy sure that Mister Tut wasn't freeze dried. Then again... I am sure Snoory has had a guest suggesting as much...
If all this fails with respect to explaining why I said "nonsense" to your post.... try dumpster diving at Micky Ds.
...sleepy now....
