Sterilization techniques are critical processes used to eliminate all forms of microbial life, including bacteria, viruses, fungi, and spores, on surfaces or in solutions, ensuring the safety and efficacy of medical, laboratory, and food products. These techniques can be physical, such as autoclaving and filtration, or chemical, such as using ethylene oxide and hydrogen peroxide gas, each chosen based on the material's tolerance and the required level of sterility.
Viral contamination refers to the presence of viruses in environments or substances where they are not intended to be, posing significant risks to public health, especially in food, water, and medical supplies. It is a critical concern in various industries, including healthcare, food production, and water treatment, necessitating stringent control measures to prevent outbreaks and ensure safety.
