Vomit often contains norovirus, rotavirus, or foodborne pathogens like Salmonella and E. coli . A proper recycling system must include a sterilization step—usually heat (distillation) or UV light after filtration. The ISS uses a high‑temperature catalytic reactor that destroys all organic molecules, including DNA and prions.
