Cooking is advisable in ideal circumstances since parasites of concern may be present. But pesticide use can make insects unsuitable for human consumption. Herbicides can accumulate in insects through bioaccumulation. For example, when locust outbreaks are treated by spraying, people can no longer eat them. This may pose a problem since edible ...
Domoic acid can cause Amnesic Shellfish Poisoning (ASP) in humans that eat them. ASP is only a concern when algae in the ecosystem increases to high levels during an algal bloom. Shellfish are susceptible to accumulation of toxins due to their morphology as filter feeders. When they filter feed algae containing domoic acid, they can have ...
Sea lettuce as a food for humans is eaten raw in salads and cooked in soups. It is high in protein , soluble dietary fiber , and a variety of vitamins and minerals , especially iron . [ 5 ] However, contamination with toxic heavy metals at certain sites where it can be collected makes it dangerous for human consumption.
The diatom lineage may go back 180 to 250 million years ago (Mya). About 65 Mya, diatoms survived a mass extinction in which roughly 85% of all species perished. [6] Until 1994, the genus was known as Nitzschia, but was changed to Pseudo-nitzschia because of the ability to form chains of overlapping cells, as well as other minor morphological differences. [8]
Therefore, algae can be considered as a natural source of great interest, since they contain compounds with numerous biological activities and can be used as a functional ingredient in many technological applications to obtain functional foods. Polysaccharides in seaweed may be metabolized in humans through the action of bacterial gut enzymes ...
Cloudy water can be a warning that there are more germs in the water than normal. Discolored or smelly water could mean there is a harmful algal bloom in the water.

All eukaryotes except for green plants and algae are unable to manufacture their own food: They obtain food from other organisms. This mode of nutrition is also known as heterotrophic nutrition . All heterotrophs (except blood and gut parasites ) have to convert solid food into soluble compounds which are capable of being absorbed (digestion).
