A farm in San Luis Obispo County, California, has reopened to the public after an outbreak of bacterial infections prompted a temporary shutdown and an investigation by public health authorities.
Brookshire Farms, located along Los Osos Valley Road in Los Osos, reopened after voluntarily closing its gates ahead of Halloween, according to KSBY News. The closure followed multiple reports of illness among visitors who had spent time at the location’s pumpkin patch in mid-to-late October.
Lab tests and environmental findings
The San Luis Obispo County Public Health Department confirmed that laboratory testing identified Escherichia coli O157 in patients tied to the outbreak, KSBY News reported. Officials said the investigation encompasses five lab-confirmed cases and eight additional suspected cases, all involving individuals who visited the property between Oct. 16 and Oct. 26.
Despite the confirmed infections among guests, environmental testing conducted at the farm did not identify the outbreak strain on site. Brookshire Farms announced on social media that all tests and environmental swabs taken on the property came back negative for the specific bacteria responsible for the illnesses.
County health officials noted that negative environmental results are not unusual in such inquiries, explaining that bacterial contamination can often be brief, fleeting and difficult to locate after time has passed. While investigators did uncover other forms of coliform bacteria and E. coli in several environmental samples, authorities told KSBY News that those particular findings did not determine the origin of the outbreak.
Community events affected by infection concerns
The health scare triggered precautions beyond the farm itself. Municipal officials in nearby Santa Maria canceled their annual post-Halloween pumpkin smashing gathering scheduled at the Elwin Mussell Senior Center, according to the Santa Maria Times. That event was designed to divert discarded holiday gourds away from landfills to curb methane emissions, but officials opted to scrap the activity because residents may have brought items purchased at the farm.
The City of San Luis Obispo similarly called off a planned Nov. 1 pumpkin event at French Park out of caution to protect public health, the Santa Maria Times reported.
Health authorities cautioned that Shiga toxin-producing E. coli infections, commonly known as STEC, can produce severe abdominal cramps, vomiting, fever and diarrhea that is often bloody. Symptoms usually begin three to five days following exposure, though they can take up to 10 days to appear. Young children under age 10 face the highest risk of experiencing severe medical complications from the illness, according to county health guidance.
Moving forward
Upon reopening its doors, Brookshire Farms thanked area residents for their messages of support throughout the temporary closure. The farm invited the public back to the property and announced it would distribute thousands of leftover pumpkins to visitors free of charge, maintaining that the crops remained safe.
Public health officials have urged anyone who visited the farm during the potential exposure window in late October and experienced gastrointestinal symptoms to seek care from a medical provider promptly and report their possible exposure.
