Answer 1

some mushrooms grow out of horse manure some grow out of cow paddies and still some grow from sheep turds, but many varieties don't grow out of animal manure.

Why are you so put off by food growing from turds, don't you understand that for thousands and thousands of years horse manure was used to grow fruits and vegetables, today it is still one of the most wanted fertilizers for organic fruits and vegetables.

Grow up and learn the facts before you act.

Answer 2

This is a common misconception that mushrooms are grown ON actual horse/cow manure. Both are included in a mixture of substrate, as I will further explain:

Growing White/Brown Mushrooms

Mushrooms are grown on a pasteurized substrate that contains a source of nitrogen and carbon.

- The carbon comes from wheat straw or hay.

- The nitrogen comes from poultry litter, stable bedding (horse manure), plus a high protein supplements such as soybean meal and feather meal.

When the carbon and nitrogen sources are mixed with gypsum (to manage the pH of the substrate) and water, a nutritionally-balanced growing medium for mushrooms is created. During that process, intense heat is generated (160F / 71C) that destroys any pests and pathogens. The substrate is then pasteurized to guarantee that no bacteria or micro-organisms remain in the substrate before the spawn (fungal seed) is added. Simply stated, mushrooms grow in ‘clean dirt’.

When you get into specialty mushrooms such as shiitake and oyster, the are in fact grown on hardwood sawdust, no manure at all.

I hope that this answers your question, and that you will not fear eating mushrooms.
