There is no question that eating uncooked bacon that has been left in a car for four hours is unsafe. Pork can carry a potentially very dangerous bacteria. All pork products should be cooked safely for as long as the package may indicate. The parasite called trichinella can be present. This will cause a person to become seriously ill.
Will become unfit for human consumption
Depends on the external temprature, it should be treated the same as an uncooked bacon, the fact that it is vacuum sealed does not mean it will last longer
Four hours at room temperature after that it begins to spoil.
The general rule of thumb is 2 hours for meat.
Unless it was freezing cold, pork left out for 5 hours is not safe to eat. Five hours is plenty of time for some nasty bacteria to grow.
No.
You can but it can cause diaria (sawy if i spelt it wrong) or you can get very sick
You do realise that there are only twenty-four hours in a day, right? Generally, a dog shouldn't be left alone for more than four hours. My Labrador Retriever is seven months old and is left alone for four hours in the morning, then I will come home at lunchtime for an hour, then he will be left alone for another four hours before I finish work.
Meat should never be left unrefrigerated over two hours, whether it it cooked or uncooked.
Yes you should throw them out.
Generally, yes. That is not enough time for previously properly stored and cooked bacon to "turn" and go bad. But don't get too comfortable with leaving food out for long periods. Things (bacterial or mold growth and chemical changes) begin to happen to it as soon as you have finished preparing it.
Yes. If the chicken is more than 48 hours old. It should be used as soon as bought or frozen right away.
