Final answer:
Strict food safety protocols, including the Hazard Analysis and Critical Control Point (HACCP) concept, prevent astronauts from getting foodborne illnesses in outer space.
Step-by-step explanation:
The prevention of foodborne illnesses in outer space is achieved through strict food safety protocols. NASA developed the Hazard Analysis and Critical Control Point (HACCP) concept to ensure absolute freedom from disease-producing bacteria and toxins in space food. This system focuses on preventing food safety problems rather than detecting them after they occur. It is important to note that some bacteria grow faster in microgravity, but the rigorous protocols and sterilization procedures implemented by NASA help minimize the risk of foodborne illnesses in space.
