not necessarily, unless someone specifically is fed on carcasses of other dead. Basically, if any body with prions is present in open environment, and only small bugs/bacteria/fungii are doing their job, they will simply decay everything, since they don't have many complex protiens in them, they don't mind eating prions. And once they die, they basically just become raw nutrients (amino acids) and then to even simpler compounds (most amino acids are not that stable outside life, would get oxidised). If we consider bigger animals decomposing, for example hyenas and vultures or crows, as long as they are not then fed upon by something that we eat (lets say cattle, or we don't directly eat them) then it is ok. If i am not wrong, some cultures basically just through theri bodies in some large pits for these animals only.
