What should you know about breastfeeding and food poisoning?

Food poisoning commonly causes nausea, vomiting, diarrhoea, abdominal pain or fever. The germs causing many foodborne illnesses usually affect the gut rather than breast milk, so stopping feeds is often unnecessary. The bigger concern is fluid loss, which can reduce the parent’s ability to care for the baby and may make feeding more exhausting. Wash hands carefully after using the toilet and before touching the baby, pump parts or food. If vomiting or diarrhoea is severe, the illness may need assessment as [Food Poisoning](/conditions/food-poisoning/).

Offer the breast as usual if you feel able. Take frequent small sips of water or an oral rehydration drink; [Oral Rehydration Therapy](/treatments/acute-and-urgent-care/oral-rehydration-therapy/) can replace fluid and salts lost through vomiting or diarrhoea. Rest, use separate towels, and avoid preparing food for others while unwell. Ask a clinician or pharmacist to check any medicine before taking it, especially if your baby is premature or has a medical condition. Do not dilute feeds or give a baby rehydration products unless their clinician specifically instructs you.

Get prompt medical help for faintness, confusion, very little urine, inability to keep fluids down, blood in vomit or stool, severe abdominal pain, or a high or persistent fever. Seek help if the baby is feeding poorly or has fewer wet nappies. Severe dehydration may require [IV Fluid Therapy](/treatments/acute-and-urgent-care/iv-fluid-therapy/). Learn more about [Vomiting](/symptoms/vomiting/), [Diarrhoea](/symptoms/diarrhoea/), [Nausea](/symptoms/nausea/) and [Fever](/symptoms/fever/).
