E. coli no puede sobrevivir en envases de cartón corrugados
High temperatures applied during the manufacture of corrugated packaging mean that bacteria such as E.coli are unable to survive in the material, said a European trade body.
FEFCO (the European Federation of Corrugated Board Manufacturers) said it had highlighted the matter following the deadly outbreak of Enterohaemorrhagic Escherichia coli (EHEC) that originated in Germany.
This strain of E. coli belongs to the bacteria group called Enterobacteriaceae. The optimum environment for these bacteria is a temperature between 25 °C and 40 °C, combined with sufficient moisture. However, they are not able to survive temperatures above 70 °C, said FEFCO.
Corrugated board is manufactured by combining layers of paper uses heating elements with temperatures between 180 °C and 200 °C.
“The material itself reaches temperatures of at least 100 °C three times, once during the manufacture of the paper itself, and twice during the process of conversion to corrugated board”, said the body.
The industry group declared that contamination of one product with another was“impossible” because each package is used only once.
After use the packaging that is recycled back into paper during which the material is again heated to temperatures exceeding 100 °C.
“With temperatures far above levels than those at which EHEC bacteria can survive occurring three times during the manufacturing process, the corrugated board industry offers an efficient solution for a safe food logistics chain and can give reassurance that the current serious outbreak will not be spread by the use of corrugated packaging,” added FEFCO.
