Team Phyllon defines the problem of foodborne illness, contamination, and large-scale recalls, a threat that is growing in frequency and carries severe human and economic costs. Using the Boar's Head Listeria outbreak as an anchoring case, the team frames how detection gaps let contamination reach consumers before anyone intervenes, affecting companies, customers, the environment, and the broader economy. They tie the problem to NASA's closed-loop ecosystem goals, arguing that a safer food system matters as much for space habitats as it does on Earth.
