Are guava producers regulated by the Mexican government?

The Mexican government requires all guava producers to adhere to:

• Approved seeds from a government-authorized distributor
• Obtain a Phytosanitary Certificate from the Ministry of Agriculture, which in fact is a Phytosanitary Certificate from SENASICA (National Service of Health, Safety, and Agrifood Quality)
• Certificate of Good Agricultural Practices (G.A.P.), and Food Safety Management (F.S.M.)
• Use of approved pesticides and disease control chemicals, as well as fertilizers. (There is no certificate for this; only proof of purchase is required)
• Product quality certificate during or before harvesting (a certificate of a laboratory analysis)
