It depends on whether it was treated properly between killing and refridgerator. I have seen cases where pigs are home slaughtered, left to hang in a warm area overnight then butchered. Naturally that meat would not have as long a shelf life as a pig killed in an abattoir, carcass cleaned, hung and split in shortest possible time and then hung to cool in an airblasting refrigeratorm cut in a cold cutting area and then stored in the fridge would give a far longer shelf life. Then again it also depends if the fridge is continually opened and shut. How big the meat is i.e. a joint or a single chop.
I have a joint in the fridge which has been there a week and is still fine.
