Why can iceberg lettuce be dangerous?

Answer 1

Warm temperatures allow certain bacteria to multiply very fast. It depends what kind of bacteria are on the iceberg lettuce as to whether or not it would be dangerous. If the lettuce has been contaminated with pathogens, it could be dangerous whether or not it has been refrigerated.

Answer 2

Lettuce does not have to be refrigerated. However, it will last longer and stay crisper, if it is refrigerated. One should always wash their lettuce before use. This will help wash away any bacteria from it, including E-Coli.

Answer 3

No Iceberg lettuce is not a healthy lettuce to eat. It contains too many nitrates, as well as being the only lettuce to actually coat your intestines with a thin coat of "slime" which does not allow for proper digestion of food.

Answer 4

Iceberg lettuce can be dangerous if it is not properly washed, or if chemicals are used on it that can cause harm if consumed without being cleaned off. Another reason is that it can be dangerous is that it contains chemicals similar to opiates. If you cut the stems on the lettuce, it will ooze a milky juice, it looks and smells like opium. Once dried it is lactucarium, or lettuce opium. It was used by the ancient Egyptians. It is still found in herbals, and used as a sedative and cough suppressant. This is commonly found in wild lettuce.
