Children are picking upwards to a greater extent than than an pedagogy inwards classrooms across New Zealand Horse dander traces flora inwards 60% of tested New Zealand classrooms

Children are picking upwards to a greater extent than than an pedagogy inwards classrooms across New Zealand, according to a study, alongside a gain of allergens from animals, including horses, beingness detected.

However, classroom cleaning protocols some the country, including daily vacuuming, convey led to much lower allergens levels than those typically flora inwards homes, the researchers reports.

Researchers collected flooring dust samples from 136 classrooms inwards 12 primary schools together with analysed them for allergens from cats, cockroaches, horses together with cows, dust mites together with peanuts.

A quarter of all classroom carpets had high plenty levels of truthful cat dander, produced inwards truthful cat saliva together with sebaceous glands, to potentially sweat respiratory symptoms inwards cat-sensitised children.

“These levels of truthful cat allergen are almost probable due to passive transfer from children’s clothing, every bit at that spot are to a greater extent than frequently than non no cats on schoolhouse premises,” said Otago University Associate Professor Rob Siebers, who was Pb writer inwards the study.

Of the 136 classrooms, 37 had detectable levels of moo-cow dander allergen, piece 82 (60%) had detectable levels of Equus caballus dander, albeit at rattling depression levels. Three of the classrooms had depression together with barely detectable levels of cockroach allergens.

Only 1 of the classrooms had measurable levels of peanut allergen, only these were too at such a depression marker every bit to travel barely detectable.

Siebers says this is probable a outcome of almost parents next schoolhouse guidelines on avoiding peanut products inwards children’s lunches.

“We believe adherence to this advice, addition frequent classroom vacuuming has resulted inwards the virtual absence of peanut allergen exposure inwards our study.”

Despite New Zealand having some of the highest levels of identify dust mite allergens inwards the world, the researchers, whose findings are reported inwards the New Zealand Medical Journal, flora levels to travel relatively depression inwards the classrooms.

“Although nosotros detected identify dust mite allergens inwards nearly all the classrooms studied, none of the levels were at a marker associated alongside respiratory symptoms,” Siebers says.

“We believe that the cleaning practices adopted past times the schools, mainly daily vacuum cleaning, were responsible for the much lower levels of allergens inwards the classrooms, compared to the domestic environment.”

Associate Professor Siebers says alongside the high prevalence of asthma together with allergy inwards New Zealand, schools should catch replacing carpets alongside smoothen flooring to trim back children’s exposure to truthful cat allergens.

The study was supported past times grants from the Health Research Council of New Zealand together with from the University of Otago.
