keresztszennyezdést

Keresztszennyezdés refers to the unintended transfer of one substance to another. This phenomenon is encountered in various fields, including food safety, pharmaceuticals, and laboratory settings. In the context of food, it describes the movement of bacteria or allergens from one food item to another. This can occur directly, such as when raw meat touches cooked food, or indirectly, through contaminated utensils or surfaces. Proper hygiene practices, like thorough handwashing and separate cutting boards for different food types, are crucial in preventing food cross-contamination.

In the pharmaceutical industry, keresztszennyezdés is a significant concern for product safety and efficacy. It can happen during manufacturing processes when residues from one drug product contaminate the equipment used for another. This risk necessitates stringent cleaning protocols and validation procedures to ensure that pharmaceutical products are pure and free from unwanted foreign substances. Similarly, in laboratory environments, cross-contamination can compromise the integrity of experiments and diagnostic tests. This can involve the transfer of biological samples, chemical reagents, or even microbial cultures between different experiments or analyses. Strict laboratory practices, such as the use of disposable equipment and careful handling of samples, are essential to mitigate this risk. The term emphasizes the importance of maintaining separation and cleanliness to prevent the unwanted mingling of materials.
