Children's packed lunches too warm to be safe: Study

NEW YORK: Tests of more than 700 preschoolers' packed lunches found that fewer than 2 percent of the meats, vegetables and dairy products were cool enough to be safe, according to a U.S. study.

One in six U.S. residents gets food poisoning every year,according to the U.S. Centers for Disease Control and Prevention (CDC), but it is unclear how many cases are caused by lukewarm sack lunches.

The study by Fawaz Almansour, a doctoral student at theUniversity of Texas in Austin, was the first to check how the food that children take to school is doing in terms of health about ninety minutes before they eat it. "It was a shock when we discovered that more than 90 percentof the perishable items in these packed lunches were kept at unsafe temperatures," Almansour said.

According to his study, published in Pediatrics, some 705 lunches packed by parents for children in full-time daycare centers were checked for the temperature of perishable food items and the number of ice packs included. The CDC says that perishable foods kept between 4 to 60 degrees Celsius (40 and 140 degrees Fahrenheit) for more thantwo hours are no longer safe to eat.

Some 39 percent of the lunches had no ice packs, while 45percent had at least one. Some 12 percent were kept in refrigerators. Still, 88.2 percent of lunches were at ambient temperatures. "Even with multiple ice packs, the majority of lunch items were at unsafe temperatures," Almansour and colleagues wrote.

Almansour said the study had been an "eye-opener". "It shows there is a problem," he added, recommending that lunches be packed with lots of ice packs and refrigerated once the children arrive at school.

Huh? The research looks genuine and is a good warning, but what kind of juvenile a solution is that? It is certainly very inconvenient to use 'ice packs' and get involved in all the complications of their storage, especially with younger commuters. Using more 'ice packs' is not practical, one bit.

Better solutions, as the comment above suggests, would include turning to lunches that do not require cooling/heating at all or broaching the old, Indian profession of 'dabbawaalas' to your area. :-)

Half the school children here take masala chips to school. What hazards that masala contains is anyone's guess.
