er a 60 °C laundering procedure; thus recommending a 60 °C laundering procedure for linen in healthcare facilities.

In the report by Smith and co-workers \[[@B16-ijerph-09-03330]\] it was found that soiled hospital terry towels initially contaminated with Gram-positive rods (predominantly *Klebsiella*, *Enterobacter* and *Serratia* spp.) and Gram-positive bacteria (predominantly *Staphylococci*) in the range between 10^7^ to 10^9^/100 cm^2^ were washed in different laundering procedures. It was found that the washing cycle with a temperature of 60 °C followed by the drying cycle at 93.3 °C was sufficient to maintain linen hygiene.

Christian and co-workers \[[@B17-ijerph-09-03330]\] also conducted experimental research on low temperature laundering of hospital textiles using economically reasonable chemicals and wash conditions. They examined the disinfection effect of laundering procedures against aerobic chemoorganotrophs, staphylococci and total coliforms. They found that low temperature washing procedures (47.8 °C) using increased concentrations of bleach eliminated all bacterial groups as effectively as the high temperature procedures (77 °C).

In the research by Blaser and co-workers \[[@B7-ijerph-09-03330]\] a comparison of laundering procedures at 71.1 °C and 22 °C was conducted. The argument of such low-temperature washing was the vast amount of energy used for laundering at 71.1 °C. The 22 °C laundering procedure included the use of low-temperature chemicals. The initial counts on the use soiled terry towels and sheet were between 10^6^ to 10^8^/100 cm^2^ with predominantly Gram-negative rods (especially *Enterobacteriaceae* and *Pseudomonadaceae*) and *Staphylococcus* species as the most common Gram-positive organisms. It was found that the bacterial counts from low-temperature and high-temperature washed fabrics were comparable. The authors therefore concluded that low-temperature washing for eliminating pathogenic bacteria from hospital laundry is as effective as high-temperature launderin
