A 10-yeаr-оld child is brоught tо the pediаtriciаn with complaints of severe abdominal cramps and bloody diarrhea that began two days ago. The child has no history of recent antibiotic use or international travel. A stool specimen is collected and sent to the microbiology laboratory for bacterial culture. In the lab, the sample is plated onto Sorbitol MacConkey (SMAC) agar. After 24 hours of incubation, several colonies appear colorless, indicating a lack of sorbitol fermentation. Confirmatory testing for Shiga toxin using a commercial EIA kit yields a positive result. What is the most likely interpretation of these results?
