What's the risk associated with leaving pork (vacuum sealed) in water at 35 °C (95 °F) for 12 hours? It's probably a common mistake with sous vide cooking, forgetting to turn the bath on.
The conditions you've described are ideal for growing a pretty vibrant culture of clostridium botulinum (botulism). Maybe you could distill some Botox serum out of it (please note that this is a flippant comment - don't try to make homegrown Botox), but please do not consider serving it as food to anyone.
Would you eat meat that has been sitting on your porch for a night?
