Which company recalled Rely tampons in 1980 after their use was linked to toxic shock syndrome?

Procter & Gamble recalled Rely tampons in 1980 after their use was linked to toxic shock syndrome.

Rely was a highly absorbent tampon marketed by Procter & Gamble in the United States. During the 1970s and early 1980s, epidemiological investigations connected tampon use—especially highly absorbent products—with toxic shock syndrome, a rare but potentially life-threatening illness caused by bacterial toxins.

The Rely product used a carboxymethyl cellulose material and compressed polyester foam. Its high absorbency allowed some users to wear it for extended periods, a practice that increased concern during the outbreak investigations. Procter & Gamble withdrew Rely from the market in 1980.

The recall helped lead to stronger tampon labeling and absorbency standards. Toxic shock syndrome was not a chemical contaminant added to the product; it was an illness associated with bacterial toxin production under particular conditions.
