Is Using Compost and Compost Tea Really Safe?

This Q&A is pulled from a collection of questions posed to me by students of my Online Permaculture Design course (PDC). Learn more with my free four-part Masterclass series, here:

Question:
After researching the safety of compost tea, food cultivation, and food safety, in general, I read a study from the UCONN college of agriculture where they sound the alarm on mulch piles, compost (both plant and manure-based) and compost tea applications noting that pathogens grow rampant in organic mulch piles. I began this research after watching countless videos of folks spraying on compost tea and later picking fruit and eating it straight off the tree without washing. I caught myself thinking "wait, am I going to kill myself doing that?". How can we be sure we are not creating a biological war zone in our mulch and compost piles and that we will not get sick by using such sprays, teas, and mulches?

About Permaculture:
Permaculture (en.wikipedia.o...) integrates land, resources, people and the environment through mutually beneficial synergies - imitating the no waste, closed-loop systems seen in diverse natural systems. Permaculture applies holistic solutions that are applicable in rural and urban contexts and at any scale. It is a multidisciplinary toolbox including agriculture, water harvesting and hydrology, energy, natural building, forestry, waste management, animal systems, aquaculture, appropriate technology, economics, and community development.
