... destinated to human food.

In this framework and for various technical reasons, we need to incorporate a fluorescent probe (NIR dyes) in our vaccine.
We would like to know if somebody know one (or more) probe of this type which have received approval from the FDA for use in a veterinarian pathway.

If this is not the case do somebody know how we can find a list of products authorized by the FDA for these applications.

Thank you in advance and have a good day

Best regards
