This season, & came together to bring comfort and joy to children and families who needed it most. 🎁❤️

Through our holiday toy drive, we donated 80 toys for children ages 18 months to five years, supporting two incredible organizations:

• UCSF Children’s Hospital (Level IV ICU): Donated in honor of a loved one who bravely fought a complex medical battle. We’re grateful to UCSF’s care teams for the compassion and lifesaving work they provide to families during unimaginable moments.

• First Step CDC at Peninsula Family Service (LifeMoves): Supporting children whose families are in emergency or transitional housing by providing early learning opportunities in a safe, nurturing environment.

We’re honored to stand with these organizations and grateful for the opportunity to help brighten young hearts during the holidays.

🚨 Did you know imported products may be put under ‘automatic detention’ if they’re deemed by the FDA to be high risk? It is then the responsibility of the importer to prove that the product is safe rather than for the FDA to prove its unsafe.

Anresco Laboratories has provided import detention sampling & testing services since 1981 and are true experts at navigating the FDA DWPE (Detention Without Physical Examination) Program. Reach out if we can be of assistance.
