Quick Answer. HowStuffWorks explains that food poisoning often occurs when a person eats spoiled food. Common symptoms of food poisoning are stomach pain, diarrhea, nausea, vomiting and cramping.
Confusion continues over coolant colors for cars. Of course, there is still the good old green stuff, but there is also orange, yellow (gold and amber), red, pink, blue and, if you mix the wrong things together, brown. Despite the rainbow of colors, all antifreeze starts out colorless.
Do not mix the orange and green colored engine coolant when adding coolant to the system or when servicing the vehicle's cooling system. Mixing the orange and green colored engine coolants will produce a brown coolant which may be a customer satisfaction issue as it looks like rust is present.
