A large biomass fire near Tracy has prompted local air officials to issue a health cautionary statement for the northern counties of San Joaquin, Stanislaus and Merced, particularly the communities of Lathrop, Manteca and Modesto. The caution is in place until the fire is extinguished.

 Smoke from fires produces fine-particulate matter, which can cause serious health problems including lung disease, asthma attacks, and increased risk of heart attacks and stroke. Where conditions warrant, people with heart or lung disease should follow their doctors’ advice for dealing with episodes of particulate exposure. Additionally, older adults and children should avoid prolonged exposure or heavy exertion, depending on their local conditions.

People with existing respiratory conditions, young children and elderly people are especially susceptible to health effects from these pollutants. Air District officials urge residents to follow their doctors’ orders when exposed to fire emissions.
