Food Safety During Pregnancy
Food safety during pregnancy is important in protecting the health of both mom and baby. Due to hormonal changes during pregnancy, a pregnant mama’s immune system can become compromised, leaving her at higher risk for contracting a foodborne illness(1). Read on to learn more about food safety during pregnancy.
What is Foodborne Illness?
Foodborne illness can be caused by eating food that has been contaminated by bacteria, viruses, or parasites, and is often referred to as food poisoning. The food can be contaminated at any time before eating or during handling (2). The main foodborne illness of concern during pregnancy is Listeria. Listeria is a bacterium that can cross the placenta and can cause issues for both mom and baby (2).
Symptoms of Foodborne Illness
There are many symptoms associated with foodborne illness. Some of the most common symptoms include (1,2):
- Stomach pain and cramps
- Fever and chills
Many of these symptoms are also associated with a normal pregnancy and the flu. This poses a greater risk for those who are pregnant, as the foodborne illness may not be identified (1). This is why food safety during pregnancy is so important – to avoid contracting a foodborne illness in the first place.
Risk of Foodborne Illness During Pregnancy
Foodborne illness poses a greater risk for those who are pregnant (2). If a mother contracts a foodborne illness within the first three months of pregnancy, this can result in a miscarriage. In later pregnancy, this can cause a baby to be born prematurely. In addition, foodborne illness could also result in a stillbirth or a baby that is born very sick (2). It is important to practice food safety during pregnancy to avoid encountering these issues.
Food Safety During Pregnancy
As mentioned, food safety during pregnancy is important to maintain the health of both mom and baby. Here are a few tips that can assist in promoting food safety (1,3):
- Clean: Prior to cooking or eating wash your hands for 20 seconds with soap and warm water, ensure you use clean utensils and cookware and wash all surfaces.
- Cook: Cook all foods to a safe internal temperature. For example, cook poultry, eggs, shellfish, and leftovers to a minimum of 74°C.
- Cross-contamination: Try to avoid cross-contamination of raw poultry, meat, fish or shellfish with cooked foods by using separate cutting boards, knives, and cooking utensils.
- Chill: Refrigerate leftovers within 2 hours of cooking, in a refrigerator that is 4°C or below. Cool hot food quickly in a shallow pan prior to covering and refrigerating.
- Defrost: Defrost frozen foods safely by placing in the refrigerator, in cold water, or in the microwave.
- Wash: Thoroughly wash fruits and vegetable with cold water, clean firm vegetables and fruit with a produce brush, and cut away any damaged or bruised areas.
