Explain what are the causes of unsafe food and beverage?

Most food that is unsafe is unsafe because of bacteria. Be it E-coli, Salmonella, Botulism or others, it causes the body to experience vomiting, abdominal pain, headache, very loose bowels, dehydration, even death.

Some foods that are unsafe have toxic molds attached typically causing similar symptoms as bacterias, but may include joint pain.
