Bottle Shocked

Most of us do it; carry around a bottle of water to sip on during the day. Or keep one in our purse or bag to drink with that packet of Crystal Light or Gatorade. This mannerism is suited more for those on the go, athletes or even people who are traveling. But what happens when something we do that is so insignificant becomes a hazard?Unknown Object “The first danger that a lot of people think about when they mention plastic water bottles is BPA,” said Pattie Olusola, an MD at UT Health Science Center in Tyler. “BPA can leak into our food from plastic water bottles and cans. When this chemical is taken in, it can do harm to brain development and cause reproduction problems in adults.” BPA, or Bisphenol A, is a chemical used to make a certain kind of plastic that lines plastic water bottles. It is also used in other household items such as aluminum cans, toys, baby bottles and canned formula, juices or milk.

Throughout her research, Olusola said the earliest study on the dangers of BPA in plastic water bottles was in 2003, with another study in 2007. She said that small amounts of the bacteria caused by BPA may cause problems but it has never been fully validated and research is still ongoing. “I think they’ve always known, but now more studies are being conducted,” she said. “The EPA, (Environmental Protection Agency) looks into products containing BPA and monitors that. As far as bacteria is concerned, the FDA makes sure that water bottles and the water you buy from the city is safe through testing. Water from a public water supply or sealed water should be safe.”

And although there has been no cases of BPA illnesses or fatalities, Olusola said that companies are remaining cautious about the chemical and have taken necessary steps to prevent consumers from being negatively affected by bisphenol. “BPA levels are low,” she said. “Some companies make all plastic water bottles BPA free, including baby bottles.” Just some of the BPA-free products available on the market includes water bottles, camping equipment and toys . The bottles come in your choice of stainless steel or plastic, and there are a variety of colors to choose from. Probably the most important feature is that the bottles are dishwasher friendly. “Bacteria can grow from backwash and the constant use of our hands,” she said. “So wash thoroughly. There are some bottles of water labeled BPA Free and they have wider mouth openings so that they can be washed easier.”

Olusola also added that BPA-free water bottles are good for the environment and for everyday use. “BPA-free water bottles are less heavy, easier to carry and climate friendly,” she said. “I think another reason why people should not use plastic water bottles is because they are filling up land fills. As long as they are BPA-free then it comes down to a preference thing when choosing plastic or stainless steel. As far as safety goes either one is safer.”

But if you’re like a lot of people and can’t help but buy a 24 pack of bottled water from the grocery store because of convenience, Olusola gives tips on how to prevent the leakage of BPA into your beverage. “City water or store-bought plastic bottled water should be safe, but I tell people to be weary of freezing your water bottles or leaving them in hot temperatures,” she said. “Leaving plastic bottles in your car or refreezing them can weaken the plastic and more BPA may come out into the water. Also, warmer conditions make bacteria grow faster.” Olusola added that if you open a bottle of water and keep it in the refrigerator then your beverage should be good for a day or two. “Refrigeration slows down bacteria reproduction,” she said. “But I wouldn’t drink out of a bottled water after 24 hours if it's been in the car.”

Olusola also gives advice to patients who frequently travel. “Outside city water, like water from a well, needs to be filtered or tested for metals or chemicals,” she said. If a filter is not available Olusola advises to boil the water before it is used for drinking in order to eliminate the majority of bacteria. And no matter how strong of a bromance you and your buddies have, you should never share water bottles due to bacteria. Unless they’re dying of course. However, BPA should be taken seriously and not disregarded. It would not cause an immediate acute illness, but it could result in long term health issues.
