MD stands for "Medical Device." It refers to any instruments, apparatus, machines, implants, or other similar or related articles that are intended to be used for human beings for the purpose of diagnosis, prevention, monitoring, treatment or alleviation of disease, injury or disability. In Europe, a MD Label is a special label that must be on all Medical Devices that are sold or used in the European Union (EU). The label must include information about the product, such as the name of the manufacturer, the intended use of the product and CE mark. To be able to sell or use a Medical Device in the EU, the device must meet certain standards and requirements set by the European Union and notified body.

PPE stands for "personal protective equipment." PPE Category 1 refers to equipment that is simple and easy to use, and has a lower level of risk. Examples of PPE Category 1 include gloves, goggles, and simple respirators. In Europe, PPE Category 1 must meet certain safety standards set by the European Union. This means that it must be designed and manufactured to protect the user without causing harm. Companies that make or sell PPE must prove that it meets these standards.

Food safe refers to the safety of food products that are used or consumed by people. In Europe, food safety is regulated by the European Union (EU) and the European Food Safety Authority (EFSA). These organizations set standards and requirements for food products to ensure they are safe to eat. To be considered "food safe" in Europe, a product must meet these standards and be free of harmful substances. This includes being free of harmful bacteria, pesticides, and other contaminants. Food products that do not meet these standards cannot be sold or used in the EU.
