☎️ Phone help

Nassau County Department of Health phone directory and contact tips

⚠️ Wrong-office check

What may not be handled by the Nassau County Health Department

Not every health-related problem belongs to the county health department. Calling the wrong office slows you down, especially when the issue is medical care, insurance, benefits, vital records, a private doctor, an emergency, or a landlord-tenant dispute that needs another agency.

Emergency medical care Call 911 for life-threatening emergencies, severe symptoms, fire, violence, poisoning, overdose danger, or immediate safety threats.
Private medical records Contact the doctor, hospital, clinic, laboratory, or provider that created the record. The county health department is not a universal medical records office.
Birth, death and marriage records Vital records may involve the correct local registrar, village/town/city clerk, New York State Department of Health, or the office where the event was filed.
Medicaid, SNAP or cash benefits These may involve social services or New York State benefit systems, not the county health department’s general public health line.
Hospital billing and insurance claims Start with the hospital, insurer, plan administrator, New York State Department of Financial Services, or the correct payer office.
Restaurant licensing outside county authority Some business licensing, zoning, fire, building, alcohol, or state-level requirements may involve separate agencies.

Nassau County’s environmental health resources cover multiple public health areas: food protection, public water supply, recreational water illnesses, swimming pools and bathing beaches, summer camps, tattoo and body piercing, groundwater protection, petroleum bulk storage, toxic and hazardous material storage, community sanitation, rodents, bed bugs, backflow prevention, onsite sewage disposal, and environmental records.

Parents and caregivers should not wait until the last minute to ask about program eligibility, referrals, forms, or evaluations. Child health programs can require documentation, provider input, school district involvement, screenings, or referral steps.

WIC appointment rules, documents, office availability, and clinic details can change. Use official Nassau County or New York State WIC resources before visiting.

📄 Forms & records

Nassau County Health Department forms, applications, inspection records and FOIL requests

Nassau County links to forms, applications, records requests, food service inspection records, FOIL requests, environmental health records, and program-specific forms. The correct path depends on the record type. A food inspection record is not the same as a FOIL request. A program application is not the same as a complaint. A medical record from a private provider is not the same as a county record.

Use official forms for Health program applications, environmental health permits, food protection resources, public health forms, and regulated facility requirements.
Use inspection records for Food service inspection history and available public facility information.
Use FOIL for Government records held by the county health department that are not already available through published resources.
Make requests specific Include facility name, address, date range, permit number, record type, and your contact information for clarification.

FOIL request tip

A narrow request is usually stronger than a broad request. Instead of asking for “all health records,” ask for the specific facility, address, program, date range, inspection type, complaint number, or permit file you need.

🚨 Preparedness

Nassau County public health emergency preparedness and alerts

Nassau County’s Health Department includes Public Health Emergency Preparedness resources, Medical Reserve Corps information, emergency notices, and public health response support. Local public health emergencies can involve disease outbreaks, weather events, water issues, hazardous exposures, mass care needs, vaccine clinics, or other community health threats.
