Pregnancy is linked with an increased demand for nutrients and the need for special attention to diet. In this extraordinary period, dietary patterns play a crucial role, not only in maintaining the health of the woman, but also in the proper development of the fetus. There is a group of food items, which despite their widespread availability, may pose a hazard due to the risk of infection, the presence of harmful substances or adverse effects on the course of pregnancy. It is therefore advisable to make prudent dietary decisions and avoid components that are not recommended during pregnancy, as they may cause complications.
Unprocessed animal-derived foods: Microbiological hazards and pregnancy-specific dietary precautions
Animal-derived foods consumed without adequate thermal processing—including raw meat, poultry, fish, eggs, and unpasteurized dairy—constitute a major reservoir of bacterial and parasitic pathogens with potentially severe implications for pregnant women. The pregnancy-associated immunosuppression heightens susceptibility to organisms such as *Listeria monocytogenes* (a placenta-penetrating bacterium linked to miscarriage, preterm labor, and neonatal sepsis), *Toxoplasma gondii* (a protozoan causing fetal neurological and ocular damage), and *Salmonella* spp. (a common agent of foodborne illness that may trigger uterine contractions). This summary outlines evidence-based guidelines for mitigating these risks through stringent food selection and preparation protocols.
