||I'm in England. I work in an office where toasters are provided. The bread that the office supplies is Kingsmill (which I don't eat as it is not Pat Akum, but which is certified by the SKA as Pat Palter). There is of course a likely/strong possibility that individuals over time have brought in their own non-pat-palter bread and that has gone into the toasters. Am I able to toast my Pat Yisrael bread in the toaster? If so, what do I have to do to be able to use the toasters (practically speaking, bearing in mind this is a working office environment)?
