Mycotoxins can be found on the mold spore and mold fragments, and therefore they can also be found on the substrate upon which the mold grows. Routes of entry for these insults can include ingestion, dermal exposure, and inhalation. Aflatoxin is an example of a mycotoxin. It is a cancer-causing poison produced by certain fungi in or on foods ...
Here's why mold grows on food, what happens when you eat it, and tips to keep food mold-free. What is mold? Molds are microscopic fungi, Josephine Wee, Ph.D., an assistant professor of food ...
Mold illness isn’t easy to define, and the path from home mold growth to debilitating chronic health symptoms is complicated. But often the story starts like this: Moisture in a home can cause ...
Molds can also grow on stored food for animals and humans, making the food unpalatable or toxic and are thus a major source of food losses and illness. [11] Many strategies for food preservation (salting, pickling, jams, bottling, freezing, drying) are to prevent or slow mold growth as well as the growth of other microbes.
Oxygen Almost all foodborne pathogens are aerobic, that is requiring oxygen to grow. Some pathogens, such as Clostridium botulinum, the source of botulism, are anaerobic. M: Moisture Water is essential for the growth of foodborne pathogens. Water activity (a w) is a measure of the water available for use and is measured on a scale of 0 to 1.0.

The molds can colonize and contaminate food before harvest or during storage, especially following prolonged exposure to a high-humidity environment, or to stressful conditions such as drought. Aflatoxin contamination is increasing in crops such as maize as a result of climate change creating better conditions for these molds.
They gather at the top of the tube where the oxygen concentration is highest. 2: Obligate anaerobes are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest. 3: Facultative anaerobes can grow with or without oxygen because they can metabolise energy aerobically or anaerobically. They gather ...
