As every year, Cofepris carries out monitoring on beaches in Mexico prior to vacation periods, in such a way that in this cycle Guerrero left the list of beaches not suitable for vacations.
The label is attributed to beaches that have too much fecal matter, so three beaches with these characteristics were found, all of them are in Baja California, they are Playa Rosarito, Playas de Tijuana and Playas de Tijuana I.
The maximum limit of enterococci faecalis allowed is 200 particles per 100 milliliters of water. Enterococci faecalis are bacteria that are normally found in feces and are usually a sign of sewage discharges on beaches.
Cofepris assures that no beach in Guerrero has more than 200 enterococcus faecalis particles per 100 milliliters of water, but it does not give details of the levels in the three Baja California beaches that were found unsuitable for vacations, a fact that is usually available for open consultation when monitoring results are announced.

What are enterococci faecalis, the fecal bacteria found on beaches in Mexico, and how do they affect them?
Playa Rosarito II was classified as not suitable for vacations last December, when Cofepris monitored the beaches for the year-end vacation period. In the previous monitoring, the one corresponding to August, Hornos, Suave and Manzanillo in Acapulco did have records of more than 200 enterococci faecalis per 100 milliliters of water.
The effects of enterococci faecalis
Enterococci are common in the human microbiota without being a danger to the host. However, if they spread to another part of the body, they can cause urinary tract infections, peritonitis, meningitis, endocarditis and, consequently, some serious conditions such as sepsis.
The great risk with enterococci faecalis is the preliminary evidence that exists that some have obtained resistance to antibiotics, a product largely of the indiscriminate use of antibiotics. An analysis published by researchers in the Department of Molecular Microbiology at the University of Washington suggests that faecalis have developed resistance to erythromycin and quinuspristin, but not to penicillin.
An enterococcal infection is unlikely to be fatal. At the macro level, enterococcal infections are more dangerous due to the required use of antibiotics and their respective potential contribution to the generation of super resistance.
The bacteria that have evolved due to the excessive use of antibiotics are under constant investigation. At UNAM they estimate that antibiotic resistance has already produced 700,000 deaths in Mexico.
