OBJECTIVE: To evaluate the impact of adherence to public health recommendations on Listeria monocytogenes food safety to limit exposure to potential food sources on micronutrient intakes of pregnant women and whether more frequent consumption of 'high-risk' foods increases risk for adverse pregnancy outcomes. DESIGN: A cohort study in women assessing Listeria exposure from an FFQ based on consumption of potential Listeria-containing food sources, the Listeria Food Exposure Score (LFES). Pregnancy status was defined as pregnant, trying to conceive, had a baby within the previous 12 months, or other. Nutrient intakes were compared with Nutrient Reference Values and self-reported pregnancy outcome history three years later. SETTING: Australia. SUBJECTS: Women aged 25-30 years (n 7486) participating in the Australian Longitudinal Study on Women's Health. RESULTS: There were weak positive correlations (r = 0·13-0·37, P < 0·001) between LFES and all nutrients, with fibre, folate, Fe and vitamin E intakes consistently below the Nutrient Reference Values in every quintile of LFES. Women in the highest quintile of LFES reported 19 % more miscarriages (rate ratio = 1·19; 95 % CI 1·02, 1·38) than those in the lowest quintile, after adjusting for important confounding factors. CONCLUSIONS: More frequent consumption of foods potentially containing L. monocytogenes is associated with higher nutrient intakes, but an increased risk of miscarriage. L. monocytogenes pregnancy recommendations require review and should include the list of 'risky' food items in addition to low-risk alternatives that would adequately replace nutrient intakes which may be reduced through avoidance strategies.
    • "is a virulent food‑borne pathogen recognized for its capability for contamination through ingestion of foodstuffs and sexual contact in pregnant women, leading to miscarriage in severe cases. [11] Through the method used to detect L. monocytogenes, this study isolated and identified cultivated bacteria from two groups of patients undergoing either early embryonic developmental arrest or artificial abortion; this work attempted to elucidate the relationship between L. monocytogenes infection and early embryonic developmental arrest. A clinical method for bacterial testing was used simultaneously, namely direct smearing onto China blue agar and blood agar plates without preliminary enrichment. "

The relevance of intrauterine infection to spontaneous embryonic death is rarely studied and remains unclear. This study aimed to investigate the relationship between intrauterine bacterial infection and early embryonic developmental arrest. Methods: Embryonic chorion tissue and uterine swabs for bacterial detection were obtained from 33 patients who underwent artificial abortion (control group) and from 45 patients who displayed early embryonic developmental arrest (trial group). Results: Intrauterine bacterial infection was discovered in both groups. The infection rate was 24.44% (11/45) in the early embryonic developmental arrest group and 9.09% (3/33) in the artificial abortion group. Classification analysis revealed that the highest detection rate for Micrococcus luteus in the early embryonic developmental arrest group was 13.33% (6/45), and none was detected in the artificial abortion group. M. luteus infection was significantly different between the groups (P < 0.05 as shown by Fisher's exact test). In addition, no correlation was found between intrauterine bacterial infection and history of early embryonic developmental arrest. Conclusions: M. luteus infection is related to early embryonic developmental arrest and might be one of its causative factors.

    • "Another example relates to Listeria food poisoning. While pregnant women are more susceptible to food poisoning, which is associated with higher rates of miscarriage, recent research has shown that by avoiding all foods that carry a risk of harboring Listeria, pregnant women are consuming fewer nutrients (Pezdirc et al. 2012).

  • [Show abstract] [Hide abstract] ABSTRACT: This essay takes J. Edward Chamberlin’s belief in the formative power of story as a starting point in order to examine the role of public health narratives and their effect on daily bodily practices and experiences. Refiguring the notion of home and homeland to include the body as home, the author explores the fear of listeria infection in pregnancy as an instance where public health narratives shape embodied experiences of the world. Ultimately, the author argues that predictive public health stories create their own state of “pathology” in which the management of health is “responsibilized” and consequently experienced as anxiety, guilt, and hyper-vigilance. This state, the author contends, is inherently linked to the political force of neo-liberalism, in which personal responsibility usurps collective or communitarian responses. Le présent article utilise la conviction de J. Edward Chamberlin concernant le pouvoir formatif des histoires comme point de départ pour examiner le rôle des récits sur la santé publique et leur impact sur les pratiques corporelles et expériences quotidiennes. Réinterprétant les concepts du foyer et du terroir pour inclure le corps comme une demeure, l’auteure examine la peur de la listériose pendant la grossesse et comment un récit sur la santé publique peut orienter les expériences corporelles dans le monde. En dernier lieu, l’auteure allègue que les histoires prédictives sur la santé publique créent leur propre état « pathologique » dans lequel la gestion de la santé est « responsabilisée » et donc ressentie comme de l’anxiété, de la culpabilité et de l’hypervigilance. Cet état, d’après l’auteure, est lié de façon intrinsèque à la force politique du néolibéralisme dans le cadre duquel la responsabilité personnelle l’emporte sur la réponse collective ou communautaire.
