You have the habit of using a plastic bottle more than once? But know that it can contain more germs than the food bowl of a dog. According to a study commissioned by TreadmillReviews.net site after a week of use without being washed, a plastic bottle has, on average, 300,000 colonies of bacteria, of which over 60% are harmful to health - which favors from skin infections to sepsis.

To get an idea, this amount is much higher than that of bacteria found in a dog bowl (47,383 CFU / cm²), the kitchen sink (3,191 CFU / cm²) or cutting board (6.8 CFU / cm²) and very close to the amount found in a container used to store toothbrush in the bathroom (331,848 CFU / cm²).

As the water bottles are usually item inseparable from the people who run on treadmills, the TreadmillReviews.net site, specializing in fitness equipment ordered with EmLab P & K laboratory research to know how many and which germs were present in four types of bottle reusable water: slide-top (just slide opening to drink), squeeze, tarraxar cover and built-in straw.

For one week, 12 people have used any of the four types of bottle without washing them. The results of the laboratory tests showed that on average, these containers were 313,499 colony forming units (CFU) of bacteria per square centimeter.

Among the four types of bottles analyzed, which showed the highest amount of germs, with over 900,000 CFU / cm² was type "slide-top". This type also contained the highest percentage (17%) of bacteria from Gram-positive coccus type, which can cause skin infection, pneumonia and sepsis.

The type "squeeze" were second with 162,000 CFU / cm², while the tarraxar cap came next with 160,000 CFU / cm². Finally, with a surprisingly smaller than the remaining amount came those that have built-in straw, with only 25 CFU / cm². Even this type of container also showed the least amount of germs harmful to health: only 8% of bacteria found were Gram-positive cocci type.

According to the specialized site, a possible reason for the low concentration of bacteria in the wells with drinking straw is that the water droplets tend to be deposited in straw background instead of staying on the surface, which ends up being less attractive for lovers of moisture germs such as bacteria.

"Based on our results, we suggest that people opt for bottles that come with straw, both by the low prevalence of bacteria as the reduction in the amount of harmful germs," wrote the fitness site.

Other recommendations of the specialized site on race tracks is, if possible opt for stainless steel bottles instead of plastic because, besides being easier to clean, this is a naturally antibacterial material, and wash daily - with water and detergent or dishwasher - your bottle.

Although the reuse of PET bottles has not been analyzed, the results suggest that in this model there is also a high level of germs.

The amount of bacteria found in each type of reusable water bottle

1. reusable bottle with lid "slide top"

Reusable water bottles with the cover "slide" ( "slide top") were the most concentrated amount of bacteria over a week of use: 933 340 UFC / cm². The types of bacteria found in this type of container were 33% Gram-negative - extremely harmful to health. Can cause pneumonia and sepsis. 17% Gram-positive cocci - harmful to health. Infections streptococcus and staphylococcus, associated with pneumonia, skin infections and sepsis. Bacilli 17% - found in nature and are generally harmless to health 33% Gram-positive rods - generally harmless

2. Reusable Bottle Squeeze

Reusable water bottles like "squeeze" were second with 162,000 CFU / cm². The types of bacteria found in this type of container were 99% Gram-negative - extremely harmful to health. Can cause pneumonia and sepsis. Less than 1% Gram-positive cocci - harmful to health. Infections streptococcus and staphylococcus, associated with pneumonia, skin infections and sepsis. 1% Gram-positive rods - usually harmless 

3. reusable bottle with tarraxar cover

Reusable water bottles with tarraxar cap were in third place with 160,000 CFU / cm². The types of bacteria found in this type of container were 98% Gram-negative - extremely harmful to health. Can cause pneumonia and sepsis. Less than 1% Gram-positive cocci - harmful to health. Infections streptococcus and staphylococcus, associated with pneumonia, skin infections and sepsis. Bacilli 1% - found in nature and are generally harmless to health 1% Gram-positive rods - generally harmless

4. reusable bottle with built-in straw

Finally, with a surprisingly smaller amount than the other, they came to have built the straw, with only 25 CFU / cm². Even this type of container also showed the least amount of germs harmful to health: only 8% of bacteria found were Gram-positive cocci type. The types of bacteria found in this type of container were 8% Gram-positive cocci - harmful. Infections streptococcus and staphylococcus, associated with pneumonia, skin infections and sepsis. 92% Gram-positive rods -. According to the usually harmless site specializing in race tracks, TreadmillReviews.net, a possible reason for the low concentration of bacteria in containers with straw is that the water droplets tend to be deposited in the bottom of tube instead of staying on the surface, which ends up being less attractive for lovers germs from moisture, such as bacteria.
