MOBILE, Ala. — Seven students at Ben C. Rain High School in Mobile became sick this week after eating brownies that a teacher had baked and brought to class, according to a source within the Mobile County Public School System. School officials said the cause appears to have been a simple baking mistake rather than anything more serious, and they stressed that no illicit drugs were involved.
According to the source, the teacher who prepared the brownies inadvertently used mayonnaise in place of cooking oil while mixing the batter. The substitution produced brownies that the students described as unappetizing and that, after eating them, gave all seven of them a bad stomachache. The students were checked by school staff and, because the symptoms were not severe, were released to their families the same day. Officials with the Mobile County Public School System confirmed the basic outline of what happened and reiterated that no drugs or other controlled substances played any role.
The incident is the kind of episode that schools work hard to prevent, but it also underscores the way a single substitution in a recipe can produce unexpected results when food is shared with a group. Mayonnaise is an emulsion of oil, egg yolks, and either vinegar or lemon juice, and although it does contain oil, its other ingredients — particularly the raw egg and the acid — behave very differently than a neutral cooking oil when heated. When used in a baked-goods recipe in place of oil, mayonnaise can change the flavor, the texture, and the moisture content of the finished product. In some recipes, a measured amount of mayonnaise is intentionally used as a substitute for oil and eggs, but in a typical brownie recipe, the swap can produce an off-tasting result that some eaters find nauseating.
What the school system has said
The Mobile County Public School System, the largest school district in Alabama and the district that operates Ben C. Rain High School, has not yet released a full written statement about the incident, but the source familiar with what happened confirmed the central facts: seven students ate brownies brought in by a teacher, the brownies had been made with mayonnaise instead of oil, the students reported stomachaches, and no drugs were involved. The source asked not to be identified because they were not authorized to speak publicly about the matter. South Alabama News has reached out to MCPSS for additional comment and will update this story if more information is released.
The episode comes at the start of a new school year in Mobile County, where classes resumed in early August and where students, teachers, and staff are still settling into routines. School districts across Alabama typically use the opening weeks of the year to remind staff and parents of policies around food allergies, homemade food, and treats brought in for birthdays or class celebrations. Many Mobile County schools now require that any food shared in a classroom be store-bought and individually wrapped, in part because of food-allergy concerns but also because of incidents exactly like this one, where a well-intentioned but mistaken substitution can leave multiple students ill at once.
About Ben C. Rain High School
Ben C. Rain High School, often referred to locally as B.C. Rain, is a public high school in the Mobile County Public School System. The school is located on Early Spring Drive in the central part of Mobile, not far from the Brookley Industrial Complex and the Mobile Bay shoreline. B.C. Rain serves students in grades nine through twelve and offers a range of academic, career-technical, and athletic programs. The school is named for Benjamin C. Rain, a former state senator and civic leader in Mobile. Like other Mobile County high schools, B.C. Rain begins its day with classes, includes a lunch period, and offers extracurricular activities in the afternoons. The school’s athletic teams are known as the Red Raiders.
Like other large urban high schools in Alabama, B.C. Rain works with a diverse student body and a staff that includes classroom teachers, instructional aides, school resource officers, school nurses, counselors, and administrators. The school nurse’s office is typically the first stop for any student who reports feeling ill during the school day, and the nurses are trained to assess symptoms, contact parents, and, when necessary, call emergency medical services. In an incident where multiple students report the same symptoms after a shared exposure, the school’s emergency operations plan is activated to make sure each student is evaluated and that parents are notified as quickly as possible.
Food safety in Mobile County schools
Food safety in schools is governed by a combination of federal, state, and local rules. The United States Department of Agriculture sets nutritional standards for school meals through the National School Lunch Program, which Mobile County participates in. The Alabama State Department of Education oversees compliance with those standards and with state-level food safety rules. At the local level, each school district sets additional policies governing what food can be brought into classrooms, what food can be sold as part of fundraisers, and how food allergies are managed.
For homemade food brought in by parents or staff, the most common restriction is a requirement that ingredients be listed so that students with allergies can make informed decisions. Some Mobile County schools go further and prohibit homemade food entirely, requiring that any treats brought in for class celebrations be commercially prepared and individually packaged. Those policies are designed to address food-allergy risks, which can be life-threatening, but they also help reduce the risk of foodborne illness in general, since commercial kitchens are typically subject to more oversight than home kitchens.
Mayonnaise in particular has been the subject of food-safety guidance for decades, because traditional recipes use raw eggs, which can carry salmonella. Commercial mayonnaise sold in the United States is pasteurized and is generally considered safe, but homemade mayonnaise and recipes that incorporate raw eggs into other preparations are a known source of foodborne illness. When mayonnaise is baked into a brownie recipe at temperatures well above the danger zone for bacterial growth, the risk of salmonella from the raw egg is greatly reduced, but the flavor of the finished product can still be unappealing, especially for eaters who are not expecting it.
What typically happens after an incident like this
When multiple students become ill after a shared food exposure at a school, the first priority is making sure the students receive appropriate medical attention and that their families are notified. School nurses document the symptoms, the time of onset, and the food that was consumed, and that information is shared with the school principal and, in serious cases, with the local health department. The Mobile County Health Department has authority to investigate suspected outbreaks of foodborne illness in schools and to take steps to prevent additional cases, including closing a kitchen or requiring additional cleaning.
For an incident like the one at B.C. Rain, where the cause was a baking error rather than a contaminated ingredient, the response from the school is typically focused on review and prevention rather than discipline. The teacher who brought the brownies is generally counseled on the school’s food policy and reminded of the importance of reviewing ingredients carefully. The students who became ill are expected to recover quickly, and any follow-up medical care is handled by their families and primary care providers. The Mobile County Public School System has not indicated that any disciplinary action is being considered in connection with the incident.
For parents who want to talk with their children about what happened, pediatricians generally recommend framing the conversation as an opportunity to learn about food safety and about the importance of paying attention to ingredients. If a child ate something that did not taste right, the standard advice is to stop eating, drink water, and tell a trusted adult. Most short-term stomachaches from a bad-tasting food resolve on their own within a few hours and do not require medical attention, but a child who develops a high fever, persistent vomiting, or signs of dehydration should be evaluated by a doctor.
