Which type of bacteria can cause food poisoning?

Staphylococci are a type of bacteria known to cause food poisoning, primarily through the consumption of contaminated food that has been improperly handled or stored. These bacteria can produce toxins that lead to symptoms such as nausea, vomiting, and diarrhea shortly after ingestion. Staphylococcus aureus, specifically, is one of the most common culprits behind foodborne illnesses, often associated with foods like dairy, egg products, and high-protein foods. Their ability to survive in a variety of environmental conditions, including heat and salt, makes them particularly resilient and capable of contaminating food.

The other types of bacteria listed, while also relevant to human health and infections, are not typically associated with food poisoning in the same manner. Micrococci, for example, are commonly found on the skin but do not generally cause foodborne diseases. Streptococci are primarily known for causing throat infections and other types of illnesses rather than foodborne illnesses. Bacilli can include various species, some of which are beneficial, while others may cause disease but are not primarily known for causing food poisoning like staphylococci do.
