The answer is yes.
The beef was tainted with the antibiotic chloramphenicol. This is why China rejected it back in March. Note that Argentina itself bans the use of chloramphenicol.
These are the side effects:
Serious and fatal blood dyscrasias (aplastic anemia, hypoplastic anemia, thrombocytopenia, and granulocytopenia) are known to occur after the administration of chloramphenicol.
There have been reports of aplastic anemia attributed to chloramphenicol which later terminated in leukemia.
Blood dyscrasias have occurred after both short-term and prolonged therapy with this drug.
