I noticed some concern around the forum about using this product and did some searching for myself. I came across some info I thought I'd share..The first bit is an e-mail response back from community outreach for Mammoth Microbes and the second is their pdf of the material safety data sheet for Mammoth.
Maureen Phenix here, Community Outreach for Mammoth Microbes. There is, unfortunately, some misinformation out there regarding the safety of the strains of bacteria in Mammoth P. We certainly would not stand behind a product that was found to be dangerous to users, and we hope that by sharing our findings related to these concerns, we can help to put your minds at ease.
Overall, it is important to understand that microbial interactions and function plays a critical part of all healthy life processes – in humans, plants and soils alike. Plants and humans depend on microbes (i.e. rhizosphere microbiome and human microbiome) and cannot function without them. In brief, Mammoth P is approved by the Department of Agriculture to use a soil additive, and is also registered OMRI listed in US and Canada. When developing Mammoth P, we consulted with several world experts in microbial ecology and bacterial pathology to ensure product safety. Mammoth P was developed at Colorado State University using our patent pending microbial trait selection platform, where we screened millions of soil microbes collected from natural and agriculture soils from across the country to identify those that most effectively facilitated plant P uptake. Our patent pending microbial trait selection platform by design cannot favor any specific microbial group or species – as the only selection criteria is based on specific nutrient cycling properties. In the case of Mammoth P, we targeted phosphorus cycling.
Regarding human health, the epidermal layer (i.e. skin) functions very well to keep bacteria out of our bodies – so bacteria do not enter through the skin, but rather through ingestion, abrasions, etc. Regardless, it is important to understand that when working with beneficial bacteria, many strains may have some affinity to be opportunistic pathogens. An opportunistic pathogen is defined as an organism that exists harmlessly as part of the normal human body environment and does not become a health threat until the body’s immune system fails. It was very important to us that all the bacteria ultimately chosen to use in Mammoth P did not appear on the NIH NIAID Emerging Infectious Diseases/Pathogens list or the US Animal Plant Health Inspection Service list of pathogenic bacteria. Likewise, at best, these bacteria are nominally classified at Biosafety Level 1 (BSL-1) which is defined by the US Center for Disease Control and Prevention (CDC) as bacterium that do not cause disease in healthy humans. However, we still strongly recommend following safe handling techniques, including: “Avoid contact with eyes, mouth, and broken skin. Do not inhale product, and wash hands after using.”
The following are some general details specifically regarding the bacterial species in Mammoth P:
1) Citrobacter fruendii is ubiquitous across most soil environments and can also be found in water, food and in the intestinal tracts of humans and many other animals. This bacterium in particular has been characterized in the scientific literature as a very active soil nitrogen cycling organism which is a critical soil function for plant health. Furthermore, although some strains of C. fruendii that inhabit animal and human intestinal tracts are considered as opportunistic, this bacterium will not compromise healthy immune systems.
2) Enterobacter cloaca is ubiquitous in soils and is also a member of the normal gut flora of many humans.
3) Psuedomonas putida has been found in the scientific literature to perform a wide range of functions from bioremediation to promoting plant health.
4) Comamonas testosteroni is ubiquitous in soils, has very low virulence and does not cause human disease.
These four microbes, among other things, are natural free living soil bacteria. However, when combined, this unique microbial formulation acts as a catalyst to maximize plant nutrient use efficiency to significantly increase cannabis yield. We developed this microbial technology to solve a problem facing cannabis producers – when nutrients are added to soils and other growth media, up to 70% becomes almost immediately unavailable to plants due to natural chemical binding and transformations. The microbes in Mammoth P can unlock bound nutrients, transforming nutrients back into plant available forms, maximizing P and micronutrient availability.

Thanks GG for posting this up! I haven't seen any of the paranoid fantasies that people are having about this product, but I'm not surprised,... one can't rely on "common" sense as usual- 
.... I like the response MP sent you, clearly they considered this long before releasing their product!
