Maternal Toxoplasmosis

Very Low Risk for breastfeeding

Safe. Compatible.
Minimal risk for breastfeeding and infant.

Toxoplasmosis is one of the most widespread infections in the world. It is caused by the Toxoplasma gondii parasite which is hosted in cats. The infected animal, through its droppings, contaminates water, fruits and vegetables and infects other animals and people.
Human infection occurs due to contact with infected cats, the consumption of unwashed fruits and vegetables, contaminated goat’s milk and the consumption of undercooked meats, among others.
The infection usually presents with mild symptoms even in infants, except in immuno-compromised persons and in the case of congenital infection during pregnancy, which is very serious.

The parasite is transmitted through the milk of several animals, but it has never been possible to confirm infection through breastmilk (CDC 2018, Lawrence 2016 p 465, Capobiango 2015), although it has been suggested in a few cases (some very old) as a probability (Brazil 2006, Bonametti 1997, Langer 1963).

Given the absence of evidence of its transmission through milk, the benignity of postnatal infection and the presence of antibodies against Toxoplasma in breastmilk, there is no reason to contraindicate breastfeeding in mothers who have suffered from toxoplasmosis in the past, during pregnancy or at the time of breastfeeding (CDC 2018, Lawrence 2016 p 225, 466 and 789).

The medication for the treatment of toxoplasmosis is usually compatible with breastfeeding (Lawrence 2016 p 789).
