The World Health Organization says there's not enough evidence to conclude that microplastics — which exist everywhere in the environment and show up in drinking water — pose any risk to human health, but it cautions that more research is needed to draw firm conclusions.

The Trump administration struck a tentative deal to lift tariffs on imported tomatoes from Mexico. But importers warn the agreement could still put protectionist roadblocks in the path of $2 billion worth of the produce.
