A concerning outbreak of leptospirosis, a rare bacterial infection typically transmitted through animal urine, has emerged among berry farm workers in Ventura County, California. Local health officials issued a public health advisory on Tuesday after identifying multiple cases among agricultural workers.
The Ventura County Agriculture Commissioner reports approximately 18 cases have been documented so far, all within the farming sector. Several affected workers have experienced severe complications, including meningitis - inflammation of the brain lining and spinal cord. Other patients reported milder symptoms like headaches and fevers.
The county's investigation began in October when a local physician noticed unusual symptoms among hospital patients. Further examination revealed most cases were connected to workers at caneberry farms using hoop house structures, which are greenhouse-like shelters for crops.
"The disease spreads through contact with contaminated water and soil, typically entering through cuts or abrasions," explains the county health department. "Rodents are primary carriers, though other mammals like livestock and pets can also transmit the bacteria through their bodily fluids."
While the illness can be serious, health officials stress there is no evidence of human-to-human transmission or risk to the general public through berry consumption. The bacteria can survive in soil for months, making agricultural workers particularly vulnerable.
The infection's timeline varies - symptoms typically appear between 2-30 days after exposure and may persist for months without treatment. Cases often begin mildly with fever, chills, and headaches, but can progress to a more severe phase affecting kidney or liver function.
The health department recommends preventive measures for agricultural workers, including:
- Regular hand washing with soap and water
- Covering cuts with bandages
- Wearing waterproof protective clothing
- Using gloves and long-sleeve shirts/pants while working
As investigations continue to pinpoint the exact source of exposure, local healthcare providers have been advised to consider leptospirosis when treating sick agricultural workers, especially those involved in berry harvesting.
