Concord Board of Health Approves Two New Appointments, Hears First Local Alpha-Gal Case

HALIFAX — May 20, 2026 — Concord Board of Health seats a new public health inspector and names its mosquito district commissioner in unanimous votes. The board approved Rachel Arsenal as a board agent after Arsenal joined the health division Monday following more than a year of experience in Westminster, and voted to appoint Public Health Director Melanie Janine as Concord's representative to the East Middlesex Mosquito Control District — a seat vacant since the prior commissioner, a local entomologist, relocated to Carlisle and became ineligible. Janine told the board the town pays roughly $22,000 annually to the district for mosquito and arbovirus surveillance. In a wide-ranging public health update, Public Health Nurse Katie Stanislausic reported Concord's first confirmed local case of alpha-gal syndrome — a red-meat allergy triggered by the lone star tick — with the affected resident confirmed to have contracted the bite in Concord, not out of state. Board member Randy Crane, an emergency physician, noted the condition's hallmark delayed immune reaction — occurring three to eight hours after red meat consumption — makes diagnosis in emergency settings unusually difficult.
