In 1911, poisoning by drinking Lysol was the most common means of suicide in Australia and New York. [5] One of the active ingredients, benzalkonium chloride , is highly toxic to fish (LC50 = 280 μg ai/L), very highly toxic to aquatic invertebrates (LC50 = 5.9 μg ai/L), moderately toxic to birds (LD50 = 136 mg/kg-bw), and slightly toxic ...
Bacterial endospores are most resistant to disinfectants, but some fungi, viruses and bacteria also possess some resistance. [10] Disinfectants are used to rapidly kill bacteria. They kill off the bacteria by causing the proteins to become damaged and the outer layers of the bacteria cell to rupture. The DNA material subsequently leaks out.

Lysol stands out for one ingredient in particular Like many other disinfecting cleaners, the active ingredient in Lysol is a quaternary ammonium compound, also referred to as a QAC or quat.
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]
Bacteria, viruses, parasites and harmful. The Center for Disease Control and Prevention estimates that every year 48 million Americans, or roughly one in six people, get sick from foodborne ...
Food-borne bacteria, in large enough numbers, may cause food poisoning, symptoms similar to gastroenteritis or "stomach flu" (a misnomer, as true influenza primarily affects the respiratory system). Some of the symptoms include stomach cramps, nausea , vomiting , diarrhea , and fever . [ 8 ]
In 57 percent of cases, the bacteria could be traced to chicken, and in 35 percent to cattle. Wild animal and environmental sources were accountable for just three percent of disease. [5] [6] The infectious dose is 1000–10,000 bacteria (although ten to five hundred bacteria can be enough to infect humans).
