My brother brought home some soymilk from the dollar tree and when I was putting them away I noticed they were warm so I put them in the refrigerator on Thursday evening(the 21st) and still haven't opened them are they safe to drink since they are unopened.Also if it was a hot day and they were in the car before he drove them home are they still safe to drink can I get sick. The brand is Westsoy plain and it looks like this............... http://www.amazon.com/Westsoy-Plain-Organic-Soymilk-Drink/dp/B0079RJHOM
