However the main function of the small intestine is the absorption of the small food particles resulting from digestion. It contains many villi which increase the surface area for absorption. The large intestine moves the material that has not been digested from the small intestine and absorbs water.
Respiratory failure caused by botulism can result in death. About 50 years ago half of all patients with botulism died, compared to just 8% today. Patients with severe symptoms may need a breathing machine, intensive medical and nursing care for several months. Fatigue and shortness of breath may linger for many years.
It's because honey (and other products such as improperly canned foods or some corn syrups) may contain bacteria called Clostridium botulinum that can cause botulism in infants. The symptoms of botulism include severe muscle weakness, poor feeding, and breathing problems and occurs in about 100 infants every year. Babies (especially those younger than 6 months) are at risk because their digestive systems are not mature enough to handle the bacteria.
