SUMMARY

Brown rot, primarily caused by fungi such as Monilinia spp. and Rhizopus stolonifera, is not considered poisonous to humans, although consuming large quantities may lead to gastrointestinal discomfort. While some fungi produce beneficial compounds used in food, others, like aflatoxin-producing species, are carcinogenic. Caution is advised when encountering unknown molds, as many can be harmful. Proper identification of mushrooms is crucial, as North American species may have toxic lookalikes compared to their European counterparts.

PREREQUISITES
  • Understanding of fungal species, specifically Monilinia spp. and Rhizopus stolonifera
  • Knowledge of mycotoxins, including aflatoxins
  • Familiarity with mushroom identification techniques
  • Basic principles of food safety regarding mold and fungi
NEXT STEPS
  • Research the effects of aflatoxins on human health
  • Learn about safe mushroom foraging practices
  • Study the role of fungi in food production, including cheese and yeast
  • Investigate the differences between North American and European mushroom species
USEFUL FOR

Food safety professionals, mycologists, foragers, and anyone interested in the health implications of consuming fungi and molds.

"Brown Rot"

Is it poisonous to humans? :bugeye:
 
Biology news on Phys.org
If your talking about the fungi that affects fruit..its not a human pathogen. Tho eating large amounts, may give you a sour stomach.
 
Fungi produce a lot of ancillary compounds, for example, aflatoxins.
Which types of extra compounds depends on the species. Some fungi flavor cheese, others like aflatoxin-producing species are carcinogenic.

If it's Monilinia spp, it possibly is okay, but I personally would not eat it.
A Rhizopus stolinifera (storage rot) is smelly for the reason that it generates some foul tasting compunds. Rhizopus rot areas become fuzzy almost right away, Molilinia does not, it just kind of caves in.
 
Hmm...what about bread mold? (another fungi)
Is it toxic/poisonous to humans?
 
Rhizopus stolonifera is bread mold. In general, when you do not know what a mold is and also know it's okay; be safe and don't eat it.


There are molds in cheese making, yeast is a fungus. These are edible.
Yet some edible cheeses are, um, stinky. So you can't tell just by smell.
Mushrooms come in lots of species, edible and super-toxic. You have to know 'em to pick 'em and eat 'em.

Short story: North American mushrooms have lookalikes in Eruope. The European lookalikes are safe, the North American ones are not. Folks in France often go on picnics and harvest wild mushrooms for lunch.

Following custom, new French Embassy staff (in the past) used to go out and get sick by picking and eating mushrooms around the Washington DC area. The Emabssy staff now knows not to do this; they have training.
I hope.
