Short Title: High Micro Foods
Responsible HRP Element: Space Human Factors and Habitability
Collaborating Org(s):
Space Human Factors Habitability (SHFH) Element
Funding Status: Completed - Task completed and produced a deliverable
Procurement Mechanism(s):
Directed
Aims:
  1. To assess the current uses of live cultures in shelf stable foods
  2. To compare levels of microbial load in these foods/supplements to current requirements and assess additional risk, if necessary.
  3. To assess expected microbial load from bioregenerative produce and developed cleaning procedures.
  4. To investigate current literature and commercial operations to provide guidance in establishing microbiological requirements and testing methods for foods with high and diversified microbial concentrations.

All aims have been achieved.  The findings are documented in a final report that was issued in August of 2011.  The evidence contained in the report demonstrates a need for further research to determine the procedures necessary for growing and processing regenerative produce and development of specific cleaning methods to mitigate microbiological risks.  The report also provides a comprehensive list of potential probiotic products, which should be evaluated to determine preferred probiotic formulations for spaceflight, and notes that research should also be conducted to determine the specific microbial testing procedures for those formulations and to assess the risk of adding the formulation to the food system.

RiskRisk of Adverse Health Effects Due to Host-Microorganism Interactions
GapMicro-101: Evaluate the effects of isolation, confinement and weightlessness on changes in the vehicle microbiome, the human microbiome, and microbial virulence.
GapMicro-102: Evaluate whether deep-space radiation has an additive or synergistic effect with weightlessness/isolation/confinement on microbial types, numbers, and virulence.
GapMicro-103: Evaluate whether atmospheric composition (for example, elevated CO2 levels) is a significant contributor to changes in the microbial profile of spaceflight.
GapMicro-202: Evaluate the contribution of changes in microbial numbers, types, and virulence on the likelihood and consequence of non-infection-based effects on health and performance, including: decrease in cognition/mood/performance/blood-brain barrier (BBB) function related to the change in the gut’s microbiome and gut-brain axis, increase in cardiovascular health risks, effects of change in gut microbiome on metabolism of nutrients, and correlation with inflammation.
GapMicro-401: Test, optimize and validate existing terrestrial or novel technologies that can maintain in-flight microbial counts, types, and virulence at terrestrial equivalent levels.
