What precaution should be taken when grilling with a marinade?

When grilling with a marinade, it's essential to discard the used marinade to avoid cross-contamination. Marinating raw meat can introduce harmful bacteria into the marinade, which can lead to foodborne illnesses if the marinade is reused without proper cooking. The marinade has been in contact with the raw meat, and therefore, if you keep it for later use or mix it with other ingredients without cooking, you may pose a risk to health.

This practice emphasizes the importance of food safety in cooking. By discarding the used marinade, you ensure that any potential pathogens introduced during the marinating process do not get transferred to other foods or other surfaces, keeping your cooking environment safe and reducing the risk of illness.
