Research Warns of Increased Bacterial Infections in Space-Grown Lettuce, Raising Concerns for Astronaut Health.

A University of Delaware research team discovered that lettuce grown under simulated microgravity conditions, imitating the International Space Station environment, is more susceptible to bacterial infections, particularly Salmonella. The study, published in Scientific Reports and npj Microgravity, highlights concerns about the potential for foodborne illness outbreaks on the ISS, where pathogenic bacteria and fungi are prevalent. The findings suggest the need for measures like sterilized seeds and genetic modifications to ensure food safety for astronauts, emphasizing the importance of understanding microbial behavior in space conditions.
