SAO PAULO (Reuters) -Mexico eased a ban on chicken shipments from Brazil, setting the restriction now only to products coming from the Brazilian state of Rio Grande do Sul, instead of a previous countrywide ban, Brazil's Agriculture Ministry said on Tuesday.

On the other hand, the ministry said in a statement that Mauritania announced a countrywide ban on imports of Brazilian chicken, while Oman suspended chicken imports coming from Rio Grande do Sul state.

Brazil last month identified a case of bird flu on a commercial farm in Rio Grande do Sul, triggering trade restrictions from dozens of countries.
