SAO PAULO, May 20 (Reuters) - Hog farmers in Rio Grande

do Sul lost an estimated 12,600 animals after floods submerged

entire towns and destroyed critical infrastructure in Brazil's

southernmost state, hog farmers lobby ACSURS said on Monday

after compiling data for two weeks.

ACSURS' President Valdecir Folador said some 30 farms were

affected by the deadly flooding, including suppliers to BRF SA ( BRFS )

and JBS SA's Seara processed foods

division.

The companies did not have an immediate comment.
