Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing ; bread , beer and wine have been produced by yeasts from the dawn of civilisation, such ...
Animal agriculture is a cause of harmful particulate matter pollution in the atmosphere. This type of production chain produces byproducts; endotoxin, hydrogen sulfide, ammonia, and particulate matter (PM), such as dust, [61] [62] all of which can negatively impact human respiratory health. [63]
Biological hazards, also known as biohazards, are organic substances that pose a threat to the health of living organisms, primarily humans. This can include medical waste, samples of a microorganism, virus, or toxin (from a biological source) that can impact human health. Biological hazards can also include substances harmful to animals.
A CDC infographic on how antibiotic-resistant bacteria have the potential to spread from farm animals. The use of antibiotics in the husbandry of livestock includes treatment when ill (therapeutic), treatment of a group of animals when at least one is diagnosed with clinical infection (metaphylaxis [1]), and preventative treatment (prophylaxis).
Like all animals, humans carry vast numbers (approximately 10 13 to 10 14) of bacteria. [3] Most are in the gut, though there are many on the skin. Most of the bacteria in and on the body are harmless or rendered so by the protective effects of the immune system, and many are beneficial, [4] particularly the ones in the gut.
Farms often pump their animal waste directly into a large lagoon, which has environmental consequences. Pigs in intensive farming. The environmental impact of pig farming is mainly driven by the spread of feces and waste to surrounding neighborhoods, polluting air and water with toxic waste particles. [1]
Pathogenic bacteria are bacteria that can cause disease. [1] This article focuses on the bacteria that are pathogenic to humans. Most species of bacteria are harmless and many are beneficial but others can cause infectious diseases. The number of these pathogenic species in humans is estimated to be fewer than a hundred. [2]
Animals often get infected with many of the same or similar pathogens as humans including prions, viruses, bacteria, and fungi. While wild animals often get illnesses, the larger danger is for livestock animals. It is estimated that in rural settings, 90% or more of livestock deaths can be attributed to pathogens.
