                                According to the CDC, contaminated shellfish are a known source of marine toxin-based food poisoning, highlighting that a primary concern among the downsides of eating mussels is the accumulation of toxins. As filter feeders, these shellfish can harbor harmful bacteria, viruses, and natural toxins from their environment, posing a risk to consumers if not sourced and prepared correctly.
