Much of my astrobiological research uses the NASA Astrobiology
guidelines, one part of these guidelines involves "Planetary
Protection." I use the Hazard Analysis and Critical Control Point
Validation (HACCP Validation) as part of my approach to the "Planetary
Protection" program. This mostly involves the sterilization of
spacecraft/landers/rovers/submarines that could contaminate new
lifeforms and their habitats. Planetary protection also includes
protection of Earth from new lifeforms. Cross-contamination is a
concern. HACCP Validations (sm) is a group of technical products
(mostly written validation protocols).
Many of the other NASA guideline areas are detection of the lifeforms
in the first place and the development of theories behind Astrobiology
itself, which I also work on. This is one of my current projects. It
is difficult to ensure planetary protection if we do not know what the
new lifeforms are doing, how they live or what they look like.
"HACCP" started with a joint project by Pillsbury foods and NASA, to
keep astronauts from getting food poisoning while on a space mission.
I worked of that for many years too.
"Validation" is the quality assurance program that ensures that the
HACCP program is working as designed. Validation is now, by US law,
is incorporated into the HACCP program and not really a separate
program anymore.

an emphasis on protection against biological contamination and
recognition of the ethical issues surrounding the export of
terrestrial life beyond Earth." -- NASA

Objective 17: Refine planetary protection guidelines and develop
protection technology for human and robotic missions. " -- NASA
