How to know if plastic is microwave safe Is it safe to stand in front of a microwave List of BPA products to avoid while you’re pregnant

A new study found exposure of the placenta in a specific component of plastic containers may have an effect on fetal brain development. The study conducted by scientists at the University of Missouri says that direct transmission of bisphenol A (BPA) from a pregnant woman to her developing baby through the placenta could lead to negative effects on fetal brain development. 

Many common household objects contain BPA, including plastic water bottles and food containers. The act of microwaving food in polycarbonate plastic food containers can result in exposure to harmful chemicals.

According to Cheryl Rosenfeld, professor of biomedical sciences in the College of Veterinary Medicine through Science Daily,

“The placenta is only a temporary organ that aids in the exchange of nutrients and waste between mother and child during pregnancy, but how the placenta responds to toxicants like BPA during pregnancy can lead to long-term health consequences.”

Numerous research has looked at the potential health repercussions, which include neurobehavioural problems, diabetes, obesity, and a variety of reproductive abnormalities.

With this said, how do you know if your plastic containers are safe to microwave? And is it even safe for pregnant women to be near a microwave oven?

The easiest way to know if a plastic container is microwave-safe is to look for a symbol at the bottom of the container. A microwave that has some wavy lines on it means the container is microwave safe. 

Other products that are not safe to microwave Polyethylene terephthalate or APET(E)

APET(E) made products are not safe to use in the microwave. Deli containers, supermarket containers, water bottles, and most cold food and display packaging containers fall under this category. They are recyclable but are not suitable for reheating.

These containers are typically used for oven-ready products. It has been crystallized to endure significantly greater temperatures. 

Is it safe to microwave plastic?

The biggest danger with microwaving plastic is that it might allow additives to seep into your foods and beverages, some of which are toxic.

Bisphenol A (BPA) increases the flexibility and durability of plastic. These chemicals cause hormone disruption and have been related to obesity, diabetes, and reproductive harm.

According to Dr. Neelima Chu, board-certified endocrinologist and internal medicine doctor with Sharp Rees-Stealy in her interview with Sharp Health News, 

“It’s important to avoid substances that interfere with hormones. These substances can lead to infertility; thyroid disease; early puberty; leukemia; breast, uterine and prostate cancers; neurobehavioral issues; obesity; and metabolic dysfunction.” 

Moreover, a recent study showed that phthalates are responsible for nearly 100,000 premature deaths each year.

BPA is predominantly found in polycarbonate plastics. These have been used in food storage containers, and baby bottles. Moreover, it can seep into meals and beverages especially when they are microwaved.

The Food and Drug Administration has disallowed the use of BPA-based materials in the packaging of infant formula and baby bottles. Manufacturers have also started producing storage with BPA-free plastics like Polypropylene. 

Studies suggest that microwaved BPA plastics can release additional hormone-disrupting chemicals like phthalates or BPA substitutes like bisphenol S and F (BPS and BPF) into foods. 

Is it safe to stand in front of a microwave

In an article in Science Friday, Timothy Jorgensen, an associate professor of radiation medicine at Georgetown University said that microwave ovens are designed to keep radiation from entering the room. 

A protective mesh screen is installed against the glass. First, these openings let you see your food. Most importantly, it keeps the lengthy microwaves inside the oven. Do not press your nose against its door. It’s safer to stand on the opposite side of the kitchen. Here, your exposure is minimal to none.
