Escherichia coli can also enter the respiratory system and cause chronic sinusitis. In neonates, it can cause meningitis. Escherichia coli is also the cause of sepsis, a dangerous condition that in extreme cases can lead to death. Other bacteria that can be dangerous to your health are the bacteria from the Pseudomonas group, particularly fond of wet environments. The bacteria are present in the environment and does not pose much of a threat to a healthy person, but if the immune system is somewhat compromised (a reduced immunity of the body), they can cause a lot of trouble. They cause, among others, infections of the middle and outer ear and a wide range of infections of the respiratory (including pneumonia), nervous, digestive, osteoarticular, and urinary systems. It can also cause myocarditis or meningitis. Pseudomonas aeruginosa can also seriously infect the cornea of the eye and cause dermatological problems.

However, again, the serious consequences of infection like those referred to above affect immunocompromised people and those struggling with such diseases as cancer, cystic fibrosis, AIDS, and burns. As the bacteria like wet and humid environments and are very resistant and active in the ice cube production process, it is necessary to take special safety precautions in the environment and exceptional care of the entire production system. Now, we move on to staphylococci, bacteria that are present virtually everywhere. They are harmless to humans as long as the conditions are not conducive. Like E. coli, they mainly cause food poisoning. Infections mainly occur in summer, due to the consumption of thawed food, including ice. Rapid absorption of exotoxins present in food causes nausea, vomiting, abdominal pain, and fever. Another important factor is fungi and moulds. These are mainly present in homes and catering establishments. They can appear every time the freezer is defrosted. Therefore, inadequately and inaccurately cleaned doors, drawers, and compartments of the appliance pose a potential risk of their entry into the frozen food. They are proven to be present in inadequately cleaned systems of appliances, such as cube makers in the catering and hotel industries. Also bear in mind that there are various products stored in freezers, each with different bacteria. The bacteria can move from one product to another, causing danger to your health if you consume them. There are also a wide variety of other bacteria that can potentially be harmful. Therefore, once you have purchased food-safe ice, be sure to store it properly.
