“…Foulon 35 proposed that a toxoplasmosis serological status survey during pregnancy should be combined with a preventive program, depending on the importance of congenital toxoplasmosis as a public health issue. In countries where the prevalence is low during pregnancy, because of low susceptibility and the small number of patients at risk of seroconversion and fetal infection, serological monitoring is not recommended as it is expensive 34 .…”

answered a quantitative questionnaire; 49.5% were seropositive for immunoglobulin (Ig) G and 3.6% for IgM. Comparative analysis of congenital toxoplasmosis cases were evaluated in 11 regions and showed an irregular distribution (p < 0.01). This difference was also observed among the pregnant women observed in each location. The results from the questionnaire show that 93% of the pregnant women had no knowledge about toxoplasmosis, and 24% presented with positive serology, but no clinical manifestation. Analysis for pregnant IgG-positive women and the presence of pets showed a statistically significant correlation (p < 0.05), suggesting that the transmission of this disease might occur in the domestic environment. Conclusions: We suggest the implementation of a triage program for pregnant women and health education to encourage their use of SUS services.

“…This is of concern as toxoplasmosis transmission can occur by the ingestion of oocytes present in the soil 35 . Pregnant women must avoid eating undercooked meat, wash their hands after handling raw meat, avoid drinking unfiltered water and unpasteurized milk, as well as foods exposed to flies, cockroaches, ants, and other insects.…”

“…Toxoplasmosis can be acquired in humans by: (i) ingesting sporulated oocysts from the environment, usually from soil, fruit or vegetables, or from water contaminated with feline faeces; (ii) ingesting cysts in food produced from an infected animal; (iii) vertical transmission from an infected mother to her fetus; (iv) blood transfusion or organ transplantation; and (v) ingesting the parasite following direct contact with products of conception during lambing [1,[4][5][6][7][8].…”

Risk factors for acute toxoplasmosis in England and Wales

et al. 2016

SUMMARYOver 300 cases of acute toxoplasmosis are confirmed by reference testing in England and Wales annually. We conducted a case-control study to identify risk factors for Toxoplasma gondii infection to inform prevention strategies. Twenty-eight cases and 27 seronegative controls participated. We compared their food history and environmental exposures using logistic regression to calculate odds ratios (OR) and 95% confidence intervals in a model controlling for age and sex. Univariable analysis showed that the odds of eating beef (OR 10·7, P < 0·001), poultry (OR 6·4, P = 0·01) or lamb/mutton (OR 4·9, P = 0·01) was higher for cases than controls. After adjustment for potential confounders a strong association between beef and infection remained (OR 5·6, P = 0·01). The small sample size was a significant limitation and larger studies are needed to fully investigate potential risk factors. The study findings emphasize the need to ensure food is thoroughly cooked and handled hygienically, especially for those in vulnerable groups.

“…Other food animals, such as sheep, goats, and horses, require outdoor access for grazing, making confinement systems of production impractical. The presence of tissue cysts of T. gondii in food animals varies by species with pigs, sheep, and goats having the highest levels followed by poultry, rabbits, dogs, and horses (Tenter, 2009). Cattle and buffalo rarely develop tissue cysts despite having high rates of seroprevalence (Dubey and others, 2005;Tenter, 2009) (fig.…”
