Final answer:
Staphylococcal food poisoning, caused by Staphylococcus aureus, results in symptoms such as vomiting, nausea, cramps, and diarrhea within one to six hours of ingestion. Unlike norovirus which has an incubation period of 12 to 48 hours, Staphylococcal symptoms present quickly and may lead to severe dehydration without proper treatment.
Step-by-step explanation:
The type of contamination that results in symptoms like vomiting within an hour after consuming food, along with nausea, cramps, and diarrhea, can be attributed to Staphylococcal food poisoning. This condition results from the ingestion of enterotoxins produced by Staphylococcus aureus when it grows in food. Symptoms can appear within one to six hours and may include severe cases that cause dehydration, which necessitates treatment for loss of fluids due to diarrhea.
Although norovirus causes similar symptoms, including vomiting and diarrhea, the incubation period for norovirus is usually between 12 to 48 hours after exposure, and symptoms typically clear within a couple of days without the need for treatment. Giardia, Cryptosporidium, and Rotavirus also cause gastrointestinal symptoms but with different incubation periods and modes of transmission. Particularly, Rotavirus symptoms show up after an incubation period of about two days but last for a week (three to eight days).
