And from my understanding a lot of packaged food is intentionally irradiated after it has been sealed. Here&#x27;s an FDA article about the process:<p><a href="http:&#x2F;&#x2F;www.fda.gov&#x2F;Food&#x2F;ResourcesForYou&#x2F;Consumers&#x2F;ucm261680.htm" rel="nofollow">http:&#x2F;&#x2F;www.fda.gov&#x2F;Food&#x2F;ResourcesForYou&#x2F;Consumers&#x2F;ucm261680....</a><p>So aside from contamination, those sandwiches are likely slightly safer than from other places since the radiation in the area will help sanitise surfaces and foods.<p>My only concern would be if the water staff used to wash up was contaminated from the soil. But assuming the water is good the food is likely good too.
