CAREER RELATED EXPERIENCE:
   
6/2002-Present Westchester County Department of Health
Bureau of Public Health Protection
Sanitarian

As of 1/2005, investigates food borne outbreaks on a countywide basis, supervises the collection of case histories and statistically analyses the results using epidemiological software for the Bureau of Public Health Protection.

Investigations and inspections are conducted of plants and facilities, housing, food service establishments other sites of potential health or environmental problems for compliance with standards of operation and sanitary procedures under the Bureau of Public Health Protection. Educates staff to compliance deficiencies, or issues notices of non-compliance and designates a period of time for correction of any offenses or deficiencies.

Inspects restaurants and temporary residences under construction to determine if the premises are being constructed in accordance with approved plans. Performs investigations of reported food borne illnesses, including the preparation of a Hazard Analysis Critical Control Point report, records for evaluation and correction food handling practices of the premises, and prepares a report of findings for use by superiors. Recommends to superiors cases where an administrative hearing or legal action may be necessary in order to obtain compliance, and may prepare the documents necessary for the hearing.

Participates on field monitory teams of the Nuclear Disaster Emergency Radiological Response Team to ensure the safety of the public in the case of a nuclear accident by physically tracking and monitoring the release of radioactivity in the field and reporting first hand to the command center. Communicates with the general public in various fields, including top management personnel, restaurant owners, landlords, tenants, homeowners, engineers, chefs, vendors, physicians and dentists. Traps, collects and identifies mosquito adults and larvae under the West Nile Virus Surveillance program.
