Lateral flow tests have been rigorously tested and are safe to use on a regular basis. Any suggestion otherwise is inaccurate and harmful misinformation.
Ethylene oxide is only used in the sterilisation of swabs and it is one of the most commonly used sterilisation tools in the healthcare industry, principally applied by manufacturers to keep medical devices safe. Any traces of ethylene oxide remaining in the lateral flow device or packaging after sterilisation are below limits that would be considered hazardous for health and comply with international standards. The types of devices that are sterilized with ethylene oxide range from devices used in general health care practices (for example, wound dressings) to more specialized devices that are used inside the body. The manufacturers have confirmed that *1-2ug/g of ethylene oxide is used in the swabs, which is well within national/international safety standards.

*Wirral In It Together. OUR ANNOTATION. 1-2 µG/G is equivalent to 1-2 ppm or parts per million. However this assertion – like all the others peppering this email – has to be taken on trust because Mr Flanagan hasn’t backed himself up, opting instead to use several unevidenced assertions. Nowhere is there any evidence derived from the specific official standards applicable to these Lateral Flow Rapid Antigen testing swabs / testing kits. So we’re still in the dark on this. Our forthcoming response will seek further information in this area.

Subject: Cancer-causing ethylene oxide inside children’s Covid19 test kits
Dear Public Health England (North West),
Your name was helpfully passed to me on 23rd March by Weatherhead High Senior Deputy Headteacher Miss N Sullivan when I raised with her via email the above pressing issue as a concerned parent.
In order to hasten the process and to avoid repetition, please proceed to the following two web links in order to appraise yourself of the details under discussion here:
On the face of it, the threat to children appears to be very serious, but thus far has neither been acknowledged nor acted upon directly, nor given the level of importance it warrants.
I would be most grateful if you could contact me as soon as possible with your proposals,
