Please briefly describe the shortcomings of laboratory testing and why we should vigorously develop food safety rapid testing technology.

Laboratory testing has some obvious shortcomings, including:

1. Time and cost: Laboratory testing usually takes a long time and costs a lot, including sample pretreatment and the use of instruments.

2. Equipment dependence: Laboratory testing usually requires highly specialized equipment and skills, which limits their popularization and application.

3. Sample pretreatment: In laboratory testing, sample pretreatment (such as extraction and purification) is a time-consuming and complicated process.

4. Unable to achieve rapid on-site detection: Due to the design of equipment and technology, laboratory detection usually cannot achieve rapid on-site detection.

This is why we need to vigorously develop the rapid detection technology of food safety. Rapid detection technology has the following advantages:

1. Fast: Fast detection technology can usually provide results in a short time, which is very important for taking timely measures.

2. Flexibility: Rapid detection technology usually uses simple equipment, and can even be tested on the spot without a laboratory.

3. Portable: Portable rapid detection equipment can be moved at any time to adapt to various environments.

4. Economy: The rapid detection technology has low cost and can save a lot of detection expenses.

Therefore, vigorously developing food safety rapid detection technology can not only overcome the shortcomings of laboratory detection, but also improve the level of food safety and better protect consumers' rights and interests.
