Cyanobacteria are found almost everywhere, but particularly in lakes and in the ocean where, under high concentration of phosphorus conditions, they reproduce exponentially to form blooms. Blooming cyanobacteria can produce cyanotoxins in such concentrations that they can poison and even kill animals and humans.
Cyanobacteria may possess the ability to produce substances that could one day serve as anti-inflammatory agents and combat bacterial infections in humans. [259] Cyanobacteria's photosynthetic output of sugar and oxygen has been demonstrated to have therapeutic value in rats with heart attacks. [260]
The microcystin-producing Microcystis is a genus of freshwater cyanobacteria and thrives in warm water conditions, especially in stagnant waters. [7] The EPA predicted in 2013 that climate change and changing environmental conditions may lead to harmful algae growth and may negatively impact human health. [20]
The FDA’s recent ban on Red Dye No. 3, set to take effect by 2027 for foods and 2028 for drugs, marks a significant step in addressing safety concerns over artificial food dyes in the U.S. food ...
Thanks to dozens of food recalls and a 10-year record for food borne illnesses, there were lots of dangerous foods this year. From romaine to raw meat, we have a few usual contenders as well as a ...
A food contaminant is a harmful chemical or microorganism present in food, which can cause illness to the consumer.. Contaminated food . The impact of chemical contaminants on consumer health and well-being is often apparent only after many years of processing and prolonged exposure at low levels (e.g., cancer).
“Added sugars in foods and drinks can make it hard for people to get the nutrients they need without getting too many calories,” according to Healthy People 2030 (from the Office of Disease ...
Iron is required for humans, as well as the growth of most bacteria. To obtain free iron, some pathogens secrete proteins called siderophores, which take the iron away from iron-transport proteins by binding to the iron even more tightly. Once the iron-siderophore complex is formed, it is taken up by siderophore receptors on the bacterial ...
