The therapeutic dose for iron deficiency anemia is 3–6 mg/kg/day. Toxic effects begin to occur at doses above 10–20 mg/kg of elemental iron. Ingestions of more than 50 mg/kg of elemental iron are associated with severe toxicity.

So, unless you're taking more than 10mg per kilogram of your bodyweight, then no.

Will you stop eating grains and vegetables because of this?
"Iron is an essential element for life on earth, participating in a plethora of cellular processes where one-electron transfer reactions are required. Its essentiality, coupled to its scarcity in aqueous oxidative environments, has compelled living organisms to develop mechanisms that ensure an adequate iron supply, at times with disregard to long-term deleterious effects derived from iron accumulation. However, iron is an intrinsic producer of reactive oxygen species, and increased levels of iron promote neurotoxicity because of hydroxyl radical formation, which results in glutathione consumption, protein aggregation, lipid peroxidation and nucleic acid modification." - http://www.ncbi.nlm.nih.gov/pubmed/22318507
Like most things that we put into our bodies, iron can be toxic. Too much can harm our health, but too little can also harm our health.
As long as you have a healthy diet and are not taking iron supplements I don't see the need to worry.
